Computed overpass times for NC Landsat dataset
LANDSAT TM5 and 7 scenes, reduced to standard book region:
landsat5_1987_nc_spm_wake.tar.gz 1.6M
landsat7_2000_nc_spm_wake.tar.gz 1.9M
landsat7_2002_nc_spm_wake.tar.gz 2.6M (Ortho-rectified)
r.history (needed for next import scripts, store in path and make executable)
glcf_landsat5_for_NC_SPM_WAKE_import.sh (convenient import script for 1987)
glcf_landsat7_2000_for_NC_SPM_WAKE_import.sh (convenient import script for 2000)
glcf_landsat7_2002_for_NC_SPM_WAKE_import.sh (convenient import script for 2002)
After import:
i.landsat.rgb b=lsat5_1987.10 g=lsat5_1987.20 r=lsat5_1987.30 i.landsat.rgb b=lsat7_2000.10 g=lsat7_2000.20 r=lsat7_2000.30 i.landsat.rgb b=lsat7_2002.10 g=lsat7_2002.20 r=lsat7_2002.30 d.rgb b=lsat5_1987.10 g=lsat5_1987.20 r=lsat5_1987.30 d.rgb b=lsat7_2000.10 g=lsat7_2000.20 r=lsat7_2000.30 d.rgb b=lsat7_2002.10 g=lsat7_2002.20 r=lsat7_2002.30NOTE: 1987 and 2002 are ortho-rectified, 2000 is not. So only 1987 and 2002 are directly comparable.
