Current and potential Landsat 7 data users - -----Original Message----- From: Paul A.

Dear Colleagues, The USGS/EROS Data Center has prepared a draft "Landsat 7 Data Policy" which will govern Landsat 7 products and services they provide to land satellite remote sensing data users (attached WordPerfect 6 document). I am sending this email is to bring a serious deficiency in this policy to the attention of the user community. The highest level Landsat Data Product EROS plans to distribute is level 1G, a "system" corrected image. The spatial accuracy of this 1G product is +/- 5-25 pixels (+/- 150-750 Meters). EROS has the systems in place to produce "precision" and "terrain" corrected images (levels 1P and 1T) which have a spatial accuracy of up to � pixel (+/- 15M). It takes an additional 6 minutes of processing time to complete this level of geometric correction. Due to pressure from the remote sensing "value added" industry, EROS has decided NOT to offer this product to their customers. Users desiring accurately georeferenced Landsat 7 data will need to do this work themselves, or contract with a "value added" provider. This policy runs contrary to the USGS/NASA intent to make Landsat 7 data more affordable and usable, and will significantly discourage use of this valuable national asset. It will add complexity, cost and delays to users already challenged to apply this data to real word problems. If you feel that the EROS Data Center should provide usable data to their customers, rather than attempting to artificially create a market for the "value added" industry at the expense of those customers, please email your concerns to the Director of the US Geological Survey, Dr. Charles Groat, at [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> with a cc to me at [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> Also, please forward this message to others who share this concern. Thank you for your attention and support, Paul A. Tessar GIS Coordinator Boulder County, Colorado P.S.
