GIS20 GIS Coverages Defining Konza Elevations

Abstract:

These data depict the elevation features of Konza Prairie. Record type 1 is a 2 meter resolution digital elevation model (DEM) of Konza Prairie, generated from 2006 LiDAR DEM data collected to standard USGS specifications (GIS200). Record type 3 is a 2010 10 meter (1/3 arc second) resolution National Elevation Dataset (NED) DEM of Konza Prairie (GIS202). Record type 4 is a 10 meter resolution NED DEM of Konza Prairie with a modified 3 kilometer buffer (GIS203). Record type 5 is a USGS topographic map of Konza Prairie (GIS204).

These data are available to download as zipped shapefiles (.zip), compressed Google Earth KML layers (.kmz), and associated EML metadata (.xml).

Data set ID:

220

Short name:

GIS20

Methods:

First, a mosaic dataset of bare earth gridded files was created using files that are available for download under each county's name at (data.kansasgis.org/elevation5/lidar/lidar2010/counties/[county]/BareEarth). The Esri tools for creating and adding rasters to mosaic datasets were used along with calculating cell size and building boundaries and overviews. Default values were used for tools.

Information relevant to the GIS data encoding

This raster shows elevation by meter in 2 meter cells. The data used to generate this raster was originally from 2010 LiDAR DEM data collected to standard USGS specifications. The Kansas Data Access and Support Center (DASC) completed the DEM mosaic and interpolation into 2 meter cells.
