The primary role of this NASA RESAC is to facilitate the integration of remote sensing data products within the natural resource management and policy arena. The distribution of data to companies and agencies of the Upper Great Lakes region is a fundamental element of that role. By leveraging the Internet-based browsing, analysis, and distribution technologies developed through the NASA ESIP at Michigan State University, this RESAC is providing low-cost access to Landsat satellite imagery for this region and beyond.

Use this site to select and order CD-ROM Landsat ETM+, TM, and MSS scenes of the Upper Great Lakes region online for $25.00/scene (TM/MSS) and ETM+ for $50/scene. This site limits access to the UGL region and does not provide searching options, but is fast, supports on-line full-resolution browsing and is compatible with Windows, UNIX, and Macintosh.

A new prototype version of a full-featured spatial database and on-line GIS for selecting, viewing, and ordering CD-ROM Landsat MSS, TM, and ETM+ scenes on-line for $25/$50 (as above). This site provides access to all the imagery in the archive, supports on-line full-resolution browsing of the imagery. Main features include data richness indicators and selectors (right click on a footprint) and real-time search engine functions that can filter for cloud cover, region, country, city, month, and year. Click on the image above to enter the archive directly.

[Note: Use with caution. There are many known bugs with this prototype version that are being worked on.... additionally, the TCS is not fully compatible with the Macintosh platform and has some graphical distortion problems when viewed on UNIX browsers.]

Developed as part of the Tropical Rain Forest Information Center (TRFIC), the archive covers most tropical biomes globally as well at the United States. The TRFIC Core System (TCS) uses ESRI's Spatial Database Engine (SDE) to connect an Oracle database with the imagery's spatial attributes. The database includes over 5,000 scenes, 2,000 covering the United States. The web application interface uses ESRI's Internet Map Server v.3 (ArcIMS 3), C++, and Java. Extensive on-line help is available. See page 18 of ESRI's Winter 1999/2000 ArcNews for more information. To connect to the TRFIC home page, follow this link:

The Imagery Cooperative Exchange (ICE)

To encourage the exchange of public domain satellite imagery, TRFIC (the NASA ESIP at MSU) and the Upper Great Lakes RESAC have established an Imagery Cooperative Exchange. The TRFIC/RESAC Imagery Archive is now accepting donations of Landsat 7 ETM+ imagery in exchange for a credit towards MSS, TM, and ETM+ images from the Archive.

Here's how it works: a single Level 1G ETM+ scene costs about $615 (including shipping and handling) from the EROS Data Center. However, once purchased, the scene is free of restrictions and can be redistributed unconditionally. TM and MSS scenes in the TRFIC Imagery Archive cost only $25 and ETM+ scene cost only $50.

Since all of the images in the TRFIC Imagery Archive are unrestricted (for example, the TM scenes from Landsat 5 were acquired through a government data-buy), TRFIC is offering an equal-value imagery exchange. When an ETM+ scene is received in the required format (see below), the donor is given a credit for scenes from the archive, free of charge. For every scene placed into the archive, we will credit your account one additional Landsat scene from anywhere in our archive. You may redeem your credited scene(s) at any time. Also, every time another user orders the scene you archived, you will be given a partial credited for that scene; every four orders of your scene by others earn you an additional scene from the collection. In addition to enhancing community access to data, the Coop helps lower your data costs.

Mission Planning: for research and education, it is helpful to know when Landsat 7 has passed over and will in the future pass-over a particular location in the Upper Great Lakes. The MSU RESAC group has developed a Landsat 7 revisit lookup table can help users identify the revisit dates for Landsat 7. The table covers the Upper Great Lakes region (paths 19 - 30) from July 1999 to January 2002. And wherever possible, the listed date of acquisition links to a GOES weather satellite image for that day and time. The GOES images can be used to assess general cloud cover on a particular date. Links to new GOES images are added regularly. A new Access7 tool called "StripBuilder" lets users view a mosaic of four thumbnail Landsat 7 scenes for the Upper Great Lakes or anywhere in the world. To launch "StripBuilder" enter the Access7 planning tool by selecting a path/row on the Access7 map and then click on a scene date to build the strip for that day.

Data Richness Info: The NASA ESIP at MSU purchases Landsat 7 imagery for the Upper Great Lakes region from the EROS Data Center (EDC) of the USGS. A search conducted on March 12, 2000 shows full coverage of the Upper Great Lakes in the EDC archive. This information can be useful as preliminary information for users wishing to purchase imagery from EDC.

Try our ArcIMS interface for access to aerial photographs from the MDNR. http://foliage.geo.msu.edu/mdnr/viewer.htm

Since the late 1930s, state and federal government agencies have conducted periodic and systematic aerial photography surveys of the State of Michigan. The Center for Remote Sensing and Geographical Information Sciences at Michigan State University maintains an archive of aerial photography collected for Michigan. Available imagery is listed in the Imagery Archive web site. Internet ordering or delivery of this material is not available.

A county index of available photography from the Center for Remote Sensing Imagery Archive can be found at:

http://www.crs.msu.edu/archive/countyindex.htm

The Basic Science and Remote Sensing Initiative (BSRSI), a research program in the Department of Geography at MSU, is developing Internet delivery technologies for remote sensing imagery and geographical data/information. Test drive the Full-resolution imagery browser with two Aerial photograph examples at:

http://tropic.geo.msu.edu/sid4aps/

These examples show how a 24 Megabyte image can be decompressed on the fly using MrSID and a series of Perl scripts through CGI.
