New elevation data available via NC OneMap
11/19/2013 9:31 AM
Elevation data is now available on NC OneMap. The new data are derived from LIDAR collected by the NC Floodplain Mapping Program and processed by the NC DOT-GIS Unit. The resolution (cell size) of the Digital Elevation Model (DEM) is 20 feet. Using the DEM, we have been able to create several new data sets that may be used in a variety of applications. Samples of some the new data sets are shown below.
Elevation data such as this can be applied to a variety of uses ranging from engineering to recreational. Watershed analysis, stream delineation, line-of-sight analysis, and cut and fill operations are a few examples of professional applications while elevation contours can be used to design a new hiking trail. These data are available as web services in ArcGIS REST, WMS, and WCS formats. The contours are also available for download from the NC OneMap GeoSpatial Portal. You may also visit our web services page to get more information.
As with all data sets available from NC OneMap, these data are available for use without restriction. So, please give the new elevation data sets a try in the Data Explorer or download them and try them out on your desktop. As always, we welcome and appreciate your feedback.
