Tags: Land Surveying, NGS Accuracy Standards Geodetic control surveys are usually performed to establish a basic control network (framework) from which supplemental surveying and mapping work are performed. The required accuracy for a control survey depends primarily on its purpose. Factors that affect accuracy are type and condition of equipment used, field procedures adopted, and…
The Wisconsin Height Modernization Program (HMP) is designed to improve the density of geodetic control stations listed in the National Spatial Reference System (NSRS) with accurate orthometric heights (elevations). The Wisconsin Dept. of Transportation (WisDOT), in cooperation with the National Geodetic Survey (NGS), initiated a program in 1998 to improve the height data throughout the State.
The National Geodetic Survey has announce that the final “Report from the 2015 Geospatial Summit on Improving the National Spatial Reference System” is now available.
