Landsat Data to be Available at No Charge

In April, the USGS released a technical announcement, outlining the plan for the release of no-charge Landsat data. Over the next 9 months, they will be opening up the Landsat archive for no-charge ordering. Please see the announcement below for details, and feel free to contact any of the Landsat staff for more information.

Imagery for Everyone…
Timeline Set to Release Entire USGS Landsat Archive at No Charge

RESTON, VA – The USGS Landsat archive is an unequaled 35-year record of the Earth’s surface that is valuable for a broad range of uses, ranging from climate change science to forest management to emergency response, plus countless other user applications. Under a transition toward a National Land Imaging Program sponsored by the Secretary of the Interior, the USGS is pursuing an aggressive schedule to provide users with electronic access to any Landsat scene held in the USGS-managed national archive of global scenes dating back to Landsat 1, launched in 1972. By February 2009, any archive scene selected by a user – with no restriction on cloud cover – will be processed automatically to a standard product recipe, using such parameters as the Universe Transverse Mercator projection, and staged for electronic retrieval. In addition, newly acquired scenes meeting a cloud cover threshold of 20% or below will be processed to the standard recipe and placed on line for at least six months, after which they will remain available for selection from the archive.

Newly acquired, minimally cloudy Landsat 7 Enhanced Thematic Mapper Plus (ETM+) data covering North America and Africa are already being distributed by the USGS over the Internet at no charge, with expansion to full global coverage of incoming Landsat 7 data to be completed by July 2008 (see timeline below). The full archive of historical Landsat 7 ETM+ data acquired by the USGS since launch in 1999 will become available for selection and downloading by the end of September 2008. At that time, all Landsat 7 data purchasing options from the USGS, wherein users pay for on-demand processing to various parameters will be discontinued.

By the end of December of 2008, both incoming Landsat 5 Thematic Mapper (TM) data and all Landsat 5 TM data acquired by the USGS since launch (1984) will become available, with all Landsat 4 TM (1982-1985) and Landsat 1-5 Multi-Spectral Scanner (MSS) (1972-1994) data becoming available by the end of January 2009. All Landsat data purchasing options from the USGS will be discontinued by February 2009, once the entire Landsat archive can be accessed at no charge.

Landsat scenes can be previewed and downloaded using the USGS Global Visualization Viewer at http://glovis.usgs.gov [under “Select Collection” choose Landsat archive: L7 SLC-off (2003-present)]. Scenes can also be selected using the USGS Earth Explorer tool at http://earthexplorer.usgs.gov [under “Select Your Dataset” choose Landsat Archive: L7 SLC-off (2003-present)]. For further information on Landsat satellites and products, see http://landsat.usgs.gov
~End of official message~

Just as an FYI - to clarify some points in the announcement. This plan will only allow 1 recipe of data to be produced. L7 data will not have any gap correction applied. The 20% or less cloud cover images will be processed automatically, the higher cloud cover scenes will be processed as ordered with no plans for prioritization of orders.

This is obviously good news, but there are some serious concerns that have been raised about limiting the types of processing available. I have cut and pasted the most recent information we have, courtesy Larry Biehl at Purdue.

In summary based on the emails below and phone calls:

- There will be only one recipe (Pixel Size 15m/30m/60m Media Type CD/DVD/Download Output Format GeoTIFF Map Projection UTM only Orientation NUP Resampling Method CC).

- When sets of data become free, one will NOT be able to order other "recipes" for those sets of data.

- Lower level Landsat products will not be available at this time.

I am sure that I do not understand the pressures being applied that resulted in this "solution". If one needs to remap these Landsat scenes to another projection for whatever reason one will have to do what one is not supposed to do .... resample already resampled scenes ... which builds spatial errors on spatial errors. Also there will be no choice for digital analysis but to base them on data which have been spatially averaged. (James Lacasse commented that they did discuss this issue with other scientists ... half said it was no problem, half said it was a problem.)

As the messages from Rachel Headley and James Lacasse below request ... please pass along concerns that any have.

Thanks for your questions, and your list of comments. Let me see if I can address some of your concerns (and theirs) in some sort of succinct manner.

1. Standard recipe only? True. This will occur as the archive is opened for free. So, for instance, on 30 September when a user can order any L7 scene for free, it will have to be the standard product. Paying for a different recipe will no longer be an option. The same will be true for L5 TM in December, and for L1-5 MSS in January.

2. A lower-level product availalbe? Not at this time. Randy Wynn is partially correct - there is a Level 0 product planned for LDCM, but there has been no direction from HQ on the Landsat 1-7 lower level products. L0Rp products are not simply files to handle, so even if they were made available, we would expect low levels of orders.

3. I did ensure that both LDCM and USGS HQ was made aware of Jim G.'s comments - I actually forwarded his email to both groups for consideration.

4. CC vs. NN. LDCM will not be able to produce NN products, so in order to be consistent across the Landsat 1-7 archive, all Standard Products will be processed with CC.

I think that covers the outstanding questions in the email traffic, although these are bound to raise more. Please continue to pass along any questions or concerns.

The following are copies of some email traffic passing around AmericaView and Purdue concerning the one recipe only:

Anyone else see a problem with this scheme? Free Landsat data is nice but the problem we have is that there is only one product "recipe". One can't get the unprocessed level 1 ...

...... Additional comments from emails included here.

As promised, here are details on the Landsat Standard L1T products recently announced by the USGS.

Standard Terrain Correction (Level 1T) (SLC-off only) The Level 1T (L1T) data product provides systematic radiometric and geometric accuracy by incorporating ground control points, while also employing a Digital Elevation Model (DEM) for topographic accuracy. Geodetic accuracy of the product depends on the accuracy of the ground control points and the resolution of the DEM used. The Standard L1T product is a processed dataset that will be available for download from USGS EROS. This dataset will include ETM+ SLC-off scenes that are over North America, have a quality score of 9, and have 10 percent or less cloud cover for data acquired prior to October 1, 2007 and 20 percent or less cloud cover for data acquired after October 1, 2007. The scenes will be processed based on the following parameters:

For reference you may find this information on the web at: http://edc.usgs.gov/products/satellite/landsat7.html. As I read through this I see that the text needs to be updated from future to present tense and to reflect the gradual expansion of both geographic coverage and instrument.

You noted in our conversation that there is a lot of e-mail traffic in your community regarding the future non-availability of other than standard recipe products.

We appreciate it if you will forward any feedback you have or receive regarding the release of these products, positive and negative, to Dr. Rachel Headley, who is included on the e-mail list. If you have additional questions please don't hesitate to call.

GIS Lessons Library

I thought the first of the following 4 new lessons on the ArcLessons library at ESRI, on: http://www.esri.com/arclesons might be particularly of interest to you all if you are using elevation data.
Joseph Kerski

1) DEM: Downloading and Analyzing
http://gis.esri.com/industries/education/arclessons/search_results.cfm?id=367
This 20-page step-by-step lesson walks a user through downloading a Digital Elevation Model from the USGS seamless data server, formatting it, projecting it, and using it within a 2-D ArcMap session and a 3-D session using 3-D Analyst. In addition, National Land Cover Data (NLCD), Digital Orthophotoquads (DOQ), and Digital Raster Graphic (DRG) data are also downloaded and used. Derivative products are created from the data, including contour lines, slope, aspect, hillshade, and TIN. Software: ArcGIS 9.2 with Spatial Analyst and 3D Analyst. Author: Joseph Kerski, ESRI.

2) Analyzing Historic and Current Population in Utah
http://gis.esri.com/industries/education/arclessons/search_results.cfm?id=370
In this Geographic Information Systems (GIS)-based lesson, students have the opportunity to investigate the spatial and temporal patterns of population change over the past 100 years in Utah, consider the reasons for those changes, investigate detailed demographic characteristics at the county and city level, and use GIS to decide where to locate their new home in Utah. My favorite part of the lesson is the graphs comparing decade-by-decade population change, coupled with the maps. One could take these procedures and guiding questions and apply them to any state, or to country-level analysis. Software: ArcGIS 9.2. Author: Joseph Kerski, ESRI.

3) Japanese American Internment
http://gis.esri.com/industries/education/arclessons/search_results.cfm?id=366
Japanese Americans living in the "military zone" along the Pacific coast of the United States, were sent to internment centers throughout the western part of the country following the bombing of Pearl Harbor and the start of war in the Pacific in 1941. Internment followed on over a half century of discriminatory immigration and land ownership laws against Asians in general and Japanese immigrants specifically. It represents the degree to which racial and cultural intolerance can be carried when mixed with the fear and hysteria of war. And it was not formally recognized in the national conscience with an apology and reparations until nearly a half century after the war's conclusion. The history of the event represented in the documents included in the Japanese American Internment site is at once a story of immigration, significant constitutional issues, racial discrimination, and the lengthy amalgamation of cultures.
The GIS activities included here are part of this larger collection of internment materials. In addition to the GIS activities the unit also includes more traditional primary and secondary resources including: letters, court records, government documents, newspaper articles & editorials, propaganda posters, political cartoons, art work, and photographs. The entire unit can be accessed on the web at: http://www.intimeandplace.org/Japanese_Internment/
Sample lesson materials are included, but teachers are encouraged to adapt the resources in the collection to best meet theirs and their students’ needs. Software: MyWorld. Author: Rick Thomas, In Time and Place.

4) Yosemite: First Visits, Lasting Impressions
http://gis.esri.com/industries/education/arclessons/search_results.cfm?id=369
Parks for the preservation of landscape, wildlife, and history are found around the world today in places as different as Costa Rica, New Zealand, and Kenya. They owe their existence in large part to the example created by the United States beginning with Yosemite in 1864. Yosemite is special in several important ways. Geologically, the park is a series of glacially carved, white granite canyons, many over a thousand feet deep. The most spectacular of these is Yosemite Valley itself. Archeologically, humans have populated Yosemite on and off going back almost to the end of the last ice age over 10,000 years ago. Villages of Miwok and Paiute natives existed in Yosemite until shortly after first contact with European settlers in the 1850's. Their legends provide an important and interesting perspective on many of the park's most spectacular features. And, historically, Yosemite has provided an important laboratory for the evolution of the national park idea. Writers like John Muir and Frederick Law Olmstead, artists like Albert Bierstadt, Thomas Hill, and Chris Jorgenson, and photographers like Carlton Watkins helped acquaint potential visitors and legislators with Yosemite's wonders in the late 1800s. Early Yosemite business people like Thomas Hutchings and David and Jeannie Curry helped shape how Yosemite was made accessible to visitors. And far sighted national leaders like Teddy Roosevelt brought a broad vision of preserving special pieces of the American environment.
Materials for download here include the GIS based activity that is part of a larger collection of Yosemite teaching resources found at: http://www.intimeandplace.org/Yosemite/
The complete collection also includes written, photo, and static map items and related activities. The goal of the unit is for students to gain an understanding of the early history of the "national park" idea by examining the emergence of Yosemite as a park. The GIS activities allow a geographic exploration of the park by inviting students to travel the trails of Yosemite with early explorers, visitors, and the U.S. Calvary.
Sample lesson materials are included here, but teachers are encouraged to adapt the resources in the collection to best meet theirs and their students’ needs. Software: MyWorld. Author: Rick Thomas, In Time and Place.

As always, we invite you to contribute to the ArcLessons library!

Urban and Environmental Modelers Datakit Available

Looking for GIS data for the U.S.?
It is with great pleasure that we announce the release of the Berkeley/Penn Urban and Environmental Modeler’s Datakit. This new website (www.dcrp.ced.berkeley.edu/research/footprint) contains more than 150 downloadable ArcMap-ready shapefiles and raster datasets for the 48 contiguous United States. The data is free to all users and includes:

• 1990 and 2000 census blocks, tracts, places, counties and MSAs from the Census;
• 1990 and 2000 net population and housing densities by census block and tract;
• Data for 20+ attribute fields for 1990 and 2000 census tracts;
• Job center locations and employment estimates for 1994 and 2003 based on County Business Patterns zipcode data;
• The nation’s highway and rail infrastructure from the US DOT’s Bureau of Transportation Statistics;
• Detailed landcover data for 1992 and 2001 from the US Geological Survey (USGS);
• Federal lands by ownership type from the USGS;
• Major rivers, streams, and waterbodies from the USGS;
• Elevation and slope from the National Elevation Database (NED);
• Riverine, palustrine, and lacaustrine wetlands from the National Wetland Inventory;
• FEMA Q3 floodzone data;
• …and much more

All shapefile and raster layers are projected to a common projection (Lambert’s Conformal Conic, North American Datum 1983); and all raster layers utilize a common 500-meter grid cell size making overlays, Boolean algebra, and spatial analysis a snap.

Each shapefile and raster dataset is located in its own directory, which is then zipped to reduce space. Zipped datasets vary in size from 500 Kb to over 50Mb. Before downloading, users can preview each dataset in a .pdf map, or review the data specifications in an .html metadata file.

The data were produced at the Institute of Urban and Regional Development (IURD) at the University of California, Berkeley; and the Penn Institute of Urban Research (Penn IUR) at the University of Pennsylvania, in cooperation with Penn's Cartographic Modeling Lab (CML). This work is funded by the National Science Foundation under its Human and Social

Dynamics Program. Project working papers and links to other projects and datasets will be forthcoming.

The data is free, and we invite all interested urban and environmental planners, analysts, modelers and enthusiasts to use it with attribution. To our knowledge, this is the first time spatially comprehensive and comparable urban and environmental GIS data is available on a single site. It is our hope that the availability of this and similar data will further narrow traditional disciplinary gaps between urban and environmental planning researchers/practitioners.

Users who uncover problems (Yes, we know "Modeler" is mis-spelled on the title banner) or might wish to add their own national data to the website should e-mail John Landis at jlan@design.upenn.edu. Feel free to forward this announcement to other potential users.

Geodesy and Revised Geoidal Height: How High is Mount Everest Exactly?

"Measuring our planet's peaks using a standardised reference will help us better understand the Earth. GOCE will result in an improved accuracy of the geoid and will facilitate the establishment of a unified global height system so that heights of the highest mountains in the world can be directly compared", said Bente Lilja Bye, Research Director from the Norwegian Mapping and Cadastre Authority. "Another benefit will be an improvement in our capabilities to predict the behaviour of the Earth, and hence provide information needed to help mitigate disasters and economically damaging events."

by Staff Writers
Paris (European Space Agency) Aug 02, 2007
How high is Mount Everest exactly? Recent surveys have come up with heights that differ by more than five metres. An expedition called the Geodetic Journey is making its way through China and Tibet to highlight the importance of geodesy and how an accurate model of the geoid from ESA's GOCE mission will lead to a unified system for measuring heights. Geodesy is concerned with measuring and mapping the shape of the Earth's surface, to the benefit of all branches of Earth sciences and has many practical applications. Although surveying techniques go back thousands of years, it traditionally involves taking very precise three-dimensional positioning of points. It is the means by which the surface of the Earth is mapped and is also essential in the field of engineering and construction.
Accurate surveying relies on knowledge of the Earth's gravity field, which defines the horizontal. However, as a result of a number of factors, such as the fact that mountains and ocean trenches make the surface of the planet uneven and materials within the Earth's interior are not uniformly distributed, the force of gravity actually varies slightly from place to place on the surface of the Earth. Due for launch in early 2008, ESA's gravity mission GOCE (Gravity field and steady-state Ocean Circulation Explorer) will provide an extremely accurate and unique picture of the Earth's gravity field and geoid. The geoid - which is defined by the Earth's gravity field - is a surface of equal gravitational potential and serves as a reference point from which to map all topographical features on the planet. GOCE will provide a model of the geoid with unprecedented accuracy and will not only be of importance in the field of geodesy, but will also lead to new insights into ocean circulation, climate change, sea-level rise, earthquakes and volcanism. Starting in Beijing, and travelling through central China to Lhasa then on to the Tibetan Plateau and ending in Shanghai, the Geodetic Journey, which is supported by ESA, will document methods of ancient surveying through to modern Earth observation. The team, made up of experts from the Norwegian Mapping and Cadastre Authority and the Chinese State Bureau of Surveying and Mapping, will promote science and technology focusing on past and present achievements within surveying and mapping, geodesy and applications to climate-change research, geo-hazards and the water cycle. Over the last 10 years an improved knowledge of the geoid has revolutionised height determination on land by GPS satellites. However, there remain discrepancies - as in the example of Mount Everest where the official height in 1999 was stated as 8850 m, but the Chinese official survey in 2005 stated it as being 8844.43 m.
Although this discrepancy may not seem huge when referring to the highest point on Earth, a global unified height system would iron out the main errors so that mountain ranges on one continent could be accurately measured against those on the other side of the world. Given the harsh and remote environments of many of the Earth's large mountain ranges such as the Himalayas or the Andes, an accurate map of the gravity field acquired from space will contribute significantly to geodesy and surveying. "Measuring our planet's peaks using a standardised reference will help us better understand the Earth. GOCE will result in an improved accuracy of the geoid and will facilitate the establishment of a unified global height system so that heights of the highest mountains in the world can be directly compared", said Bente Lilja Bye, Research Director from the Norwegian Mapping and Cadastre Authority. "Another benefit will be an improvement in our capabilities to predict the behaviour of the Earth, and hence provide information needed to help mitigate disasters and economically damaging events."

Martin Waldseemüller's 1507 map
compiled by Nora Parker, Senior Managing Editor, Directions Magazine

"The historic map was in the news this week because German Chancellor Angela Merkel officially transferred the map to the Library of Congress in a ceremony that took place on Monday, April 30. The map is important for many reasons, not the least of which is that it is the first known map to depict a separate Western hemisphere, and to identify 'America.' The Library of Congress published an article about the map and its acquisition that is good background reading. (The map has actually been housed at the Library of Congress since 2001, and the purchase - from Prince Johannes Waldburg-Wolfegg for $10 million - was completed in 2003.)"

Nikolas Schiller's Aerial Imagery Art
compiled by Nora Parker, Senior Managing Editor, Directions Magazine

"Nikolas Schiller contacted me about an in-depth article that appeared about him and his work in the Washington Post last month. Schiller's art/cartography is difficult to describe - it's one of those "you have to look at it to get the idea" kinds of things. A few words that come to mind: hypnotic, rebellious, weird, surreal, beautiful. Below is a quilt pattern generated using an image of the University of California at Los Angeles (UCLA). As a quilter, this one appealed to me, but it's only one example of the art he's cranking out at a rate of at least one map every other day at The Daily Render."

LANDSAT Data Continuity Mission

"For more than 30 years, Landsat satellites have collected data of the Earth...
The Landsat Data Continuity Mission (LDCM) is the future of Landsat satellites. It will continue to obtain valuable data and imagery to be used in agriculture, education, business, science, and government.

The Landsat Program provides repetitive acquisition of high resolution multispectral data of the Earth's surface on a global basis. The data from the Landsat spacecraft constitute the longest record of the Earth's continental surfaces as seen from space. It is a record unmatched in quality, detail, coverage, and value."
(introduction from the website)

NASA Goddard has established a website for the LDCM Mission, located at: http://ldcm.gsfc.nasa.gov
Located there are a number of materials providing status of the planning for the LDCM. While there is not a lot of detailed schedule information present, there is an RFI posted for the Mission Operations Element, as well as documents relating to the spacecraft.

How to solve problems downloading data from the USGS seamless data server

Have you ever received a data extract error message when you are downloading elevation, land cover, digital raster graphics, or other data from the USGS seamless data server (http://seamless.usgs.gov)? There is a wealth of data on the site, and I receive questions every so often from folks who are frustrated when they get so close to downloading but the last step doesn’t work. Read on.

First, make sure your popup blockers are off, because the seamless server uses popup windows. Or, do the following: Most software will allow you to hold the Ctrl key while selecting your area to disable the pop up blocker for that instance.

Second, the extract error you are receiving may be due to a conflict with Internet Explorer and Windows XP service pack 2.
Add the extract site as a trusted site, as follows:

1) In Internet Explorer, go to Tools---> Internet Options ---> Security Tab
2) Click on Trusted Sites (third icon in the window)
3) Then click the SITES button. A new window should appear where you can add a website.
4) At the bottom of the page, Uncheck the box beside --Require server ....
5) In the first box type in http://extract.cr.usgs.gov
6) Click Add --- The website should appear in the second box labeled Websites

Also, if you are using Windows XP service pack 2, click on the custom level button just above the OK button on the security tab. Scroll down to the downloads section and make sure all three options are enabled.

GPS to GIS Resources

The NPS Intermountain Region developed a GPS to GIS web site a few years ago that is quite informative on this topic.
You can view it at http://www.nps.gov/gis/gps/gps4gis/
Theresa Ely, National Park Service

~~~~~~~~~~~~~~~~~~~~~

You might receive some questions in your work concerning the bringing in your GPS points into your GIS or mapping software. Whether you use a full GIS package for this or with "mapping software", the plethora of tools available these days to do this in 2D and 3D modes is truly amazing. These include OziExplorer, National Geographic Topo!, ArcGIS, ArcExplorer, MapTech Terrain Navigator, DeLorme TopoQuads and TopoUSA, EasyGPS, USA PhotoMaps, TopoFusion, and more. Some are free; and some you pay for, but the cost may be worth it. Some are even web based these days - for example, see www.gpsvisualizer.com where you can map your GPS coordinates on a web-based map!

I recently borrowed and read the book "GPS Mapping: Make Your Own Maps."
This very helpful book enabled me sort out in my mind the advantages and limitations of many of these tools.

GIS Training and Reference Sheets for ArcGIS 9

Three common questions many new (or even long time) GIS users often have are:

- How can I take a map image (scanned or from the web or elsewhere) that is not geo-referenced and make it line up correctly with other maps in my GIS?
- I have GIS layer that I need to make changes to on the map. How do I do this?
- I want create my own layer of features by drawing them into the map. How does this work?

If you are interested in quick guides that will get you up and running on these tasks for ArcGIS 9, access them at www.gistrainingsource.com/resources.html
