ground condition
Two foot contours were generated according to FEMA specifications using Terra Scan and Terra Modeler software packages from Terra Solid. The contours were cut into 5000 x 5000 square foot tiles and spot elevations were added. The contours were generated from LiDAR data previously delivered under Aero-Metric project number 1040317. The contours and spot elevations were delivered in Arc GIS 9.1 personal geodatabases. Contours are referenced to the Illinois State Plane Coordinate System, east zone, (U.S Survey feet) and places on the NAD 83/97 (horizontal) and NAVD 88 (vertical) datums.
