Published to allow joining of spreadsheet data to county geometry in ESRI Maps for Office or Map Analysis Tools, contains Iowa DOM County Code (1-99) as a small integer, Census County FIPS as a both an string and integer. This data was originally created by the Iowa DNR and digitized from USGS 7.5' topographic maps.Click on the data tab above to see an example of expected data. OCIO has a tutorial on how to join your spreadsheet to this Feature layer to create a new feature layer with your county based information. Please contact patrick.wilke-brown@iowa.gov.

This dataset contains commonly used codes for counties and polygons representing boundaries for counties of the State of Iowa. Boundaries were developed from a set of 99 individual coverages of the Public Land Survey System (PLSS) for each county in the state. The PLSS coverages were digitized from paper copies of 7.5' topographic quadrangle maps. River boundaries were also digitized from 7.5' maps.

This coverage contains polygons representing the county boundaries of the state of Iowa. COUNTY was developed from a set of 99 individual coverages of the Public Land Survey System (PLSS) for each county in the state. The PLSS coverages were digitized from paper copies of 7.5' topographic quadrangle maps. River boundaries were also digitized from 7.5' maps. This version also encompass' the Iowa-Nebraska Compact of 1943.

This coverage contains polygons representing the Iowa Boundary, it was derived from a coverage of county boundaries, called COUNTIES, of the state of Iowa. COUNTIES was developed from a set of 99 individual coverages of the Public Land Survey System (PLSS) for each county in the state. The PLSS coverages were digitized from paper copies of 7.5' topographic quadrangle maps. River boundaries were also digitized from 7.5' maps.

Vector polygon map data of property parcels from Polk County, Iowa containing 175,356 features.

Property parcel GIS map data consists of detailed information about individual land parcels, including their boundaries, ownership details, and geographic coordinates.

Property parcel data can be used to analyze and visualize land-related information for purposes such as real estate assessment, urban planning, or environmental management.

Available for viewing and sharing as a map in a Koordinates map viewer. This data is also available for export to DWG for CAD, PDF, KML, CSV, and GIS data formats, including Shapefile, MapInfo, and Geodatabase.

This GIS coverage represents an approximation of the public drainage district boundaries in Iowa. It also represents the infrastructure of the drainage districts, which includes tiles, and ditches. This information was digitized mainly from maps provided by county governments, usually the drainage clerk in that county. The accuracy of this coverage varies widely and should be used mainly as a guide, not exact ground conditions or locations.

The bedrock geologic map portrays the current interpretation of the distribution of various bedrock stratigraphic units present at the bedrock surface. The bedrock surface is buried by unconsolidated surficial sediments (mostly Quaternary) over most of its extent, but this surface coincides with the modern land surface in areas of bedrock exposure. The map is consistent with all available data including drill records and well samples, as well as surface bedrock exposures (both natural and man-made) and shallow-to-bedrock soils units (NRCS county soils maps). Mapped stratigraphic intervals are portrayed primarily at the group level (i.e., a grouping of bedrock formations), each characterized by distinctive lithologies (rock types) summarized in the map key and associated metadata. The distribution of bedrock units was mapped to conform to the current map of bedrock topography (elevation of the bedrock surface). The structural configurations of relevant stratigraphic datums were intercepted with the bedrock topographic surface to produce the map contacts. The line style shown on the bedrock geologic map qualitatively reflects both data density and degree of certainty of individual stratigraphic contacts. Detailed line work is possible in areas of modern bedrock exposure, but more generalized line work (smooth and more sweeping forms) is portrayed in areas of sparser data control. The new bedrock map is, in part, a revised and updated compilation of seven multi-county bedrock maps prepared between 1998 and 2004 as part of Iowa's STATEMAP program (funded through U.S. Geological Survey). These maps were further supplemented with other STATEMAP bedrock compilations for portions of northeast and eastern Iowa, although much of the bedrock geology shown for northeast Iowa represents new and previously unpublished information. Bedrock faults are displayed in the map as sharp linear features offsetting mapped stratigraphic units.

This coverage represents the current state boundary of Iowa. It was developed by digitizing, from 7.5' USGS Topgraphic maps, the sections of each county on a digitizing table, and thereafter dissolving them into county boundaries. Dissolving the counties into one state boundary was done, and later work added corrections from the Missouri River 1943 Compact Line..

This vector tile basemap was created for use by the Iowa DOT with layers maintained by the Cartography team within Systems Planning. This basemap is a general reference set of data that includes information about transportation features (roads, railroads, airports and structures), as well as boundary information (state, county, and municipal boundaries), and surface water features (stream and lake information). The transportation features represent both the primary system as well as the local systems and rail features. The boundaries represent political jurisdictions as well as selected public interest lands. Surface waters include stream and lake locations. Given the nature of the basemap, the sources for this data are derived from many different sources, mainly from authoritative sources from within the Department of Transportation but also from authoritative sources from without. The basemap is scheduled to be updated on a quarterly cycle and the older versions will be archived.
