- Abstract: This datasets contain a statewide coverage of 500 foot contours derived from the 10 meter National Elevation Dataset's (NED) Digital Elevation Model (DEM).
The following data is available for download:
ELEVATION.Contours500Ft is a statewide dataset of contour lines at a 500 foot interval for cartography and approximate elevation identification. Elevation information is stored in the 500 Foot contour lines in an attribute
ELEV associated with each contour isoline.
The native spatial reference for this dataset is UTM Zone 12N, NAD83. There are no constraints or warranties with regard to the use of this dataset. Users are encouraged to attribute content to: State of Utah, SGID. This contour dataset was created by AGRC.
- This dataset has not been updated recently.
AGRC has 2 meter contours derived from 2 meter LiDAR collected in 2006 for Salt Lake County. No smoothing has been applied to the contour data but a
Smooth Line in ArcMap with a
50 meter Smoothing Tolerance cleans the data up nicely. Although the data is refered to as 2 meter, the contour intervals are .5 meter.
To download areas of the contours refer to this image map to help find your ares of interest. Or this shapefile index can be used to determine what files to download. These contour shapefiles cover 4,000x4,000 meter blocks. This data has a UTM NAD83 meters projection.
