ImageAmerica 20001002 map ISGS GIS Database /imagetiles1ft This is an Arc/Info polygon data set showing the index to photographic tiles used to compile one-foot resolution ortho-rectified digital images of the Des Plaines watershed in southeastern Wisconsin and northeastern Illinois. Tile name and bounding coordinates are identified for each polygon. See *path_name_suppressed*/1ft_images.html for details about the images. Spatial index for associated photographs. 20000325 20000326 ground condition complete unknown -088.17 -087.75 42.75 41.80 none digital orthophoto ortho-imagery ortho image ortho-images TerraSource Terra Source digital image digital imagery digital photography digital photographs none Illinois (keyword) (repeat this line for each keyword) None None.
