MrSid compression 20:1 of mosaic of Landsat Thematic Mapper 7 multispectral satellite image path 69 row 18 (August 9, 2000) for Kenai Fjords National Park.
This Kenai Fjords image was created by the National Park Service Alaska Landcover Mapping Program. A satellite image from the August 9, 2000 TM7 overpass for path/row 69/18 was used to create the image. Coverage for the Park area is incomplete. The point of Cape Aialik was beyond the image coverage as were some of the offshore islands of the Maritime Refuge.
The mosaic was created using the 30m visible bands (3,2,1) merged with the 15m panchromatic band. The resulting image has a 15m pixel size. The panchromatic band contains some infrared information that “enhances” the true color image.
The mosaic is useful down to approximately 1:40,000. The source imagery was generated by the USGS MRLC program and was delivered in Alaska Albers-WSG84 projection. The final image was reprojected to NAD 27 using the ERDAS IMAGINE rigorous transformation.
