Title: Impervious Land Cover of Wyandotte County, KS
Geospatial_Data_Presentation_Form: vector digital data
Description:
Abstract:
Dataset depicts hardscape polygon features (man-made surfaces that are impermeable to water) within Wyandotte Co., KS. Provided in Esri vector shapefile format in Kansas North State Plane coordinates.Such impermeable features would include all man-made hard surfaces such as structures, roads, parking lots, sidewalks, driveways, pools, and patios. All areas not coded impervious are by default pervious areas and are coded as such.Features were classified into 3 basic classes: buildings; roads; & other impervious surfaces (e.g. sidewalks, driveways, etc.) Remaining areas were classed as 'pervious', e.g. grass, forest, natural water surfaces such as lakes.Source data was aerial imagery with a 1’ spatial resolution and associated LIDAR data, supported by planimetric vector data provided by GSS to vendor.
Purpose:
Dataset depicts man-made impervious surface (a hard area that prevents water from percolating or seeping into the earth) cover for general planning and display uses. It is not to be used for high-accuracy engineering or for tax assessment purposes.
Impervious cover can be used to study potential precipitation runoff in a given watershed. Increased runoff intensifies water drainage and other water flow into water channels and water bodies, and can have negative impacts on the environment, especially flooding impacts.

Source_Contribution:
LiDAR data was used to confirm and digitize impermeable areas to supplement aerial orthophotography.
The LiDAR data was previously collected under Contract number 00036574 with Kansas Department of Administration. The original data was in UTM zone 14N and was converted to Kansas State Plane North 1501 for this use. The data set includes the area of Wyandotte County, Kansas. The origination of the LiDAR data was in compliance with specifications, recommendations, and guidelines of the National Digital Elevation Program (NDEP) and the American Society for Photogrammetry and Remote Sensing (ASPRS) and Other High Quality Digital Topography.
Process_Step:
Process_Description:
Semi-automated feature extraction was performed using the color imagery and LIDAR provided and then modified through photo interpretation and heads up digitizing of the aerial imagery. The entire image was panned at a scale of about 1:1,000 and heads up digitized into an ArcGIS 10 geodatabase. The data set topology was validated to ensure there were no overlapping polygons. The data was put through an internal and external QC procedure.
