Until someone generates and hosts the all the U.S. tiles for SeeYou

online, make your own:

 

I. Get sat photos from https://zulu.ssc.nasa.gov/mrsid/mrsid.pl

 

II. setfw.bat gdalinfo.exe gdalwarp.exe from OpenEV_FW_162.zip:

Re-project and crop. GeoTiff file input / various output formats. No

MrSid input (So get MrSid Viewer from www.lizardtech.com and export

geotifs). Nasty DOS interface. Source and binaries available online

(14.4 MB zip for dos package with the works)

 

http://www.remotesensing.org/gdal/index.html (see downloads and major

doc entry points)

http://www.remotesensing.org/gdal/gdal_utilities.html

 

To make it work in win98 I:

1) Edited SetFW.bat per instructions

2) Increased environment space in DOS window from "Auto" to 1024

(overkill?)

3) Reloaded missing imagehlp.dll from win98 CD

 

OR ELSE, NOT RECOMMENDED

 

III. Leica ERDAS ViewFinder 2.1

View, Re-project and output in GeoTiF format. View of MrSid did not

seem to capture projection info, preventing re-projection. GeoTIF to

GeoTiF reprojection and Output to file worked, but I haven't figured

out how / whether it will crop for tile making.

 

Windows interface, slow. No cropping - no good in my book!
