ImageMap USA™ is a versatile and cost effective satellite imagery product that delivers seamless coverage of the United States at 15-meter resolution. Created from over 450 virtually cloud-free Landsat 7 scenes from 1999 to the present, ImageMap USA™
has your area covered!
The mosaic was produced using strict photogrammetric procedures. Ground control was collected from 1:24,000 topo maps and the eDEM™ product was used for terrain correction. All of the individual scenes were orthorectified after the AT adjustments. The 30m natural color bands were then fused with the15m B&W band. Finally, the individual scenes were color balanced to create the finished mosaic. In sharp contrast to some seemingly similar products on the market, ImageMap USA™ is being continuously updated, particularly in urban areas, to keep the data as current as possible.
What makes this product even more unique is that it is offered in a hill-shaded version, adding a fantastic new perspective to Landsat imagery. The hill-shaded version was created by merging the ImageMap USA™ data with a shaded relief DEM. This process accentuates subtle terrain features and highlights drainage patterns and elevation trends not visible in a two-dimensional image. Hill-shaded products are most useful in applications that involve interpretation of complex topography, but can provide stunning enhancement to any application.
