Contour lines were generated at 2 foot intervals by county using Kansas LiDAR Bare Earth DEMs collected from 2015 through 2018. The source LiDAR Bare Earth DEM tiles are 1 meter resolution USGS QL2 data. A contouring script developed by the Iowa Department of Natural Resources was adapted to create Kansas contours at every 2 feet, 10 feet at a time. Contour lines were then simplified using a 2 foot tolerance, and lines less than 100 feet were removed. There is a identifier in the attribute table for 10 foot contour lines. Generalization of the contours lines over water bodies and roads will have a triangular appearance due to their lack of elevation data.In steep terrain, it is possible that the individual contours lines may cross each other. Due to the processing steps of creating individual lines and then merging lines into a single file, overlaps may exist and have not been and will not be fixed.For more detailed information on the Kansas LiDAR project areas: LinkPresentation at the 2023 Kansas Association of Mappers conference: LinkThe full Kansas geospatial catalog is administered by the Kansas Data Access & Support Center (DASC) and can be found at the following URL: https://hub.kansasgis.org/
