"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!
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.
