3. Significant time savings in field surveying using GPS Accurate determination of floodplain boundaries Precise control for digital ortho imagery Accurate control for reliable Digital Elevation Models Improved elevation control for GIS base maps Subsidence monitoring in mining and karst regions Infrastructure monitoring (e.g. dam and floodwall) Falmouth, KY - 1997 The Cincinnati Enquirer National Height Modernization Program Facilitate mapping and planning for Floodplain management Homeland Defense Economic Development Height Modernization will provide accurate, reliable heights using GPS with traditional leveling.

4. National Height Modernization Program FY06 funding

5. 10,461 benchmarks remain in NGS database 20 % reported “not found” or in “poor condition” 23 % in last 25 years were reported as “good” Only 12 % reported as “good” in last 10 years NSRS benchmarks in Kentucky Kentucky Height Modernization Program

7. Congressman Hal Rogers October 25, 2004 "I am pleased to announce today that Kentucky will receive funding for Height Modernization in NOAA’s fiscal 05 budget." Kentucky Height Modernization Program and in FY06 too!

8. The goal of the Kentucky Height Modernization Program is to bring accurate and reliable heights to any location in the Commonwealth at any time. The realization of this goal has three Phases: 1. Establishment of geodetic control to improve the regional geoid model and provide a reference frame for surveying and remote sensing measurements. 2. Development of an accurate Digital Elevation Model (DEM) from data collected by Light Detection and Ranging (LIDAR) and calibrated to the geodetic control. 3. Creation of products which make the geodetic control and DEM accessible to a broad range of users, by packaging it with state- wide digital orthophotography. Kentucky Height Modernization Program
