• 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)

"I am pleased to announce today that Kentucky will receive funding for Height Modernization in NOAA’s fiscal 05 budget."

and in FY06 too!

The goal of the Kentucky Height Modernization Programis 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.
