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.

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.

Existing ROW layer was created by contacting county assessor's offices and based off of parcel data received from them. Each county has different levels of accuracy. If a county did not have a GIS parcel dataset, ERMS was utilized. strip maps were pulled from ERMS, georectified, and traced over to created the boundary. This dataset is not complete.

The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation.Census Blocks are statistical areas bounded on all sides by visible features, such as streets, roads, streams, and railroad tracks, and/or by nonvisible boundaries such as city, town, township, and county limits, and short line-of-sight extensions of streets and roads. Census blocks are relatively small in area; for example, a block in a city bounded by streets. However, census blocks in remote areas are often large and irregular and may even be many square miles in area. A common misunderstanding is that data users think census blocks are used geographically to build all other census geographic areas, rather all other census geographic areas are updated and then used as the primary constraints, along with roads and water features, to delineate the tabulation blocks. As a result, all 2020 Census blocks nest within every other 2020 Census geographic area, so that Census Bureau statistical data can be tabulated at the block level and aggregated up to the appropriate geographic areas. Census blocks cover all territory in the United States, Puerto Rico, and the Island Areas (American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the U.S. Virgin Islands). Blocks are the smallest geographic areas for which the Census Bureau publishes data from the decennial census. A block may consist of one or more faces.The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB).

This includes all primary, secondary, local neighborhood, and rural roads, city streets, vehicular trails (4wd), ramps, service drives, alleys, parking lot roads, private roads for service vehicles (logging, oil fields, ranches, etc.), bike paths or trails, bridle/horse paths, walkways/pedestrian trails, and stairways.

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.

This data set represents generalized bare earth 2 foot elevation contours of Pottawattamie County, Iowa, in the UTM projection, Zone 15, NAD83 Datum. The contours were developed using elevation data from the state of Iowa's LiDAR program. The original 1 meter lidar grids were generalized to 3 meter resolution, and the contouring program applied with a 2 foot interval processed 10 feet at a time, so the program would have enough memory to complete. Contour lines were simplified using a 2 foot tolerance, and lines less than 100 ft in length were discarded. Ten foot index contours are identified in the attribute table. Contours crossing water features sometimes have a triangular appearance due to lack of lidar returns over water and should be ignored.
