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/
The 30-m USGS National Elevation Dataset grids stored on DASC for W, WC, EC, and E regions of Kansas were downloaded and mosaicked. Using ArcGIS Pro (v2.9), vertical units were converted from meters to feet, and then these new data were converted to 5-ft contours. All polyline features less than 0.001667 degrees in length (approximately 180 meters, or six 30-m pixel lengths) were then deleted to eliminate very small features. According to DASC metadata, the component raster grids were published in 1999, indicating that the entire dataset pre-dates any inclusion of LiDAR.
This digital dataset release of the La Junta, Colorado and Kansas quadrangle is composed of previously published elevation contours, structure contours on the limits of the Morrison, Dakota, and Purgatorie Formations, and geologic formational data. The digitizing of this map is to provide a more accessible dataset to be available for public usage. The original dataset was part of an eight-part series of maps in Colorado and Kansas, this map modified in part by reconnaissance by G.R. Scott in 1968. The entirety of this dataset includes both spatial and non-spatial data held in a singular, GeMS compliant geodatabase. This geodatabase includes a geologic map, geologic map feature class holding contact and fault lines, iso value lines, structure contours and other geologic lines, geologic map units, and well data; nonspatial data recorded in standalone tables such as a description of map units, glossary, data source reference, geomaterials dictionary, and their entities and attributes. Data source references include web links to published standards, data dictionaries, and any other referenced data within the published map.

The Kansas Tagged Vector Contour (TVC) dataset consists of digitized contours from the 7.5 minute topographic quadrangle maps. Coverage for the state is incomplete. Contour interval varies. The Kansas TVC dataset was developed to facilitate the production of the Kansas 5 and 10 foot DEM dataset. The original TVC dataset was provided by the U.S. Geological Survey and processed by the Data Access and Support Center (DASC).The 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/
The minimum depth-to-flood (DTF) map for eastern Kansas shows the approximate flood depth needed to inundate a location on the floodplain relative to nearby channel bottom elevation values. Channel bottom elevation values are obtained from pixels comprising the synthetic stream network, which is defined using the traditional hydrologic assessment procedure:1) Prepare the bare-earth digital terrain model (DTM) raster dataset for analysis2) Fill all of the depressions up to their spillover point (creating FIL = filled DTM)3) Compute the D8 flow direction map (FDR) using FIL4) Compute the flow accumulation map (FAC) using FDR5) Apply a threshold to FAC. Values exceeding the threshold for the synthetic stream network (STR)Then apply these additional steps to compute DTF values:6) Break STR into segments and record their connectivity7) Process each segment using the FLDPLN ("Floodplain") model to create a flood library for the segment. FLDPLN simulates continuous flooding from 0 up to some maximum depth, with floodwaters originating from nearby STR pixels so that depths are relative to FIL channel bottom elevation values.
This dataset is the result of measurements of groundwater levels in the Equus Beds aquifer near Wichita, Kansas, in January 2016. Potentiometric surfaces are interpolated for the shallow and deep parts of the aquifer, and rasters of the potentiometric surfaces are included in this data release. Wells were classified as being screened in the shallow or deep parts of the aquifer based on station name (some wells have a layer identifier in the station name) or, if no indication of aquifer layer was given in the station name, based on the depth of the well; wells with depths less than 80 feet below land surface were classified as shallow and wells with depths of 80 feet or deeper were classified as deep. Contours with a 5 foot interval were produced from the rasters and used to map the water levels in the aquifer. The water level measurements can be used to estimate storage-volume change in the study area between predevelopment (circa 1940) and January 2016 the historic low in 1993 and January 2016Íž and January 2015 and January 2016.

This geodatabase includes spatial datasets that represent the High Plains aquifer in the States of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. Included are: (1) polygon extents; datasets that represent the aquifer system extent, (2) raster datasets for the altitude of the top and bottom surfaces of the High Plains aquifer, (3) altitude contours of the top surface and of the bottom surface used to generate the surface rasters. The altitude contours are supplied for reference. The extent of the High Plains aquifer is from the digital dataset U.S. Geological Survey Data Series 543 (USGS DS 543), and as a references, the digital version of the aquifer extent presented in the Groundwater Atlas of the United States (the U.S. Geological Survey Hydrologic Atlas 730-D, -E, and -C, (USGS HA 730-D, -E, -C). The altitude contours for the top surface of the High Plains aquifer are from digital datasets of U.S. Geological Survey Open-File Report 99-263 (USGS OFR 99-263), using the 1980 water-level data. The altitude contours for the bottom surface of the High Plains aquifer are from the U.S. Geological Survey Open-File Report 98-393 (USGS OFR 98-393). The altitude of the bottom surface, or base, was originally from the High Plains Regional Aquifer-System Analysis study. The resultant top and bottom altitude values were interpolated into surface rasters within a GIS using tools that create hydrologically correct surfaces from contour data, derive the altitude from the thickness (depth from the land surface), and merge the subareas into a single surface. The primary tool was an enhanced version of "Topo to Raster" used in ArcGIS, ArcMap, Esri 2014. The raster surfaces were corrected for the areas where the altitude of an underlying layer of the aquifer exceeded the altitude of an overlying layer.

This data set consists of digital base of aquifer elevation contours for the High Plains aquifer in the central United States. The High Plains aquifer extends from south of 32 degrees to almost 44 degrees north latitude and from 96 degrees 30 minutes to almost 104 degrees west longitude. The outcrop area covers 174,000 square miles and is present in Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. This digital data set was created by digitizing the base of aquifer elevation contours from a 1:1,000,000 base map created by the U.S. Geological Survey High Plains RASA project (Gutentag, E.D., Heimes, F.J., Krothe, N.C., Luckey, R.R., and Weeks, J.B., 1984, Geohydrology of the High Plains aquifer in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming: U.S. Geological Survey Professional Paper 1400-B, 63 p.) The data should not be used at scales larger than 1:1,000,000.

This digital spatial data set consists of the aquifer base elevation contours (50-foot contour interval) for part of the High Plains aquifer in the central United States. This subset of the High Plains aquifer covers the Republican River Basin in Nebraska, Kansas, and Colorado upstream from the streamflow station on the Republican River near Hardy, Nebraska, near the Kansas/Nebraska border. In Nebraska, the digitized contours extend to the South Platte, Platte, and Little Blue Rivers. In Colorado and Kansas, the digital contours extend to the edge of the High Plains aquifer. These boundaries were chosen to simplify boundary conditions for a computer simulation model being used for a hydrologic study of the Republican River Basin.
