The Education Facility point feature class represents public and private primary, secondary, and post-secondary school facilities in the Des Moines, Iowa metropolitan area. This dataset was created for a FEMA grant project (2008 Legislative Pre-Disaster Mitigation Grant Program, LPDM-2008-IA-77-002) to develop data and a methodology for performing GIS-based Disaster Mitigation Act of 2000 (DMA2000) Multi Hazard Mitigation Plan Risk Assessments. The data were developed from local, state, and national sources and prepared by the University of Northern Iowa GeoInformatics Training, Research, Education and Extension Center (GeoTree ) between May 2010 and April 2011. The data were accepted and are maintained by the City of Des Moines and Des Moines Area Regional GIS partners. This dataset was developed for use in the Des Moines Area Regional GIS, which supports public safety response and emergency management in the Des Moines metropolitan area and surrounding counties. The Des Moines Area Regional GIS is a shared data repository hosted by the City of Des Moines. The Regional GIS partnership includes City of Des Moines, Polk County, and several cities within Polk County. Each partner is responsible for maintaining data for their respective jurisdiction.

Geospatial data about Des Moines County, Iowa Subdivisions. Export to CAD, GIS, PDF, CSV and access via API.

This digital, geographically referenced data set was developed to identify the county boundaries of the Des Moines 9 County Regional GIS community.This feature class is one many feature classes developed for and maintained by the Des Moines Area Regional GIS for the purpose of performing internal and external functions of the local government it covers.

Planimetric Building Footprint features. In 2006, the Des Moines Regional GIS group contracted with Sanborn to digitize the planimetric features utilizing 3D stereo digitizing methods and GIS processing required under the RFP. The Program Management task included coordination and oversight of the NewCom Technology tasks; incorporating the imagery and photogrammetric data from the spring of 2006 flight, stereo digitizing the planimetric features and GIS processing of the impervious surface features to ensure clean topological data structure for subsequent area / polygon calculations. Maintenance of the data includes heads-up digitizing using the orthophoto images.

Sanitary Sewer Structures was created from the importing of the City of Des Moines Engineering departments MGE sewer database into a geodatabase. Design of the geodatabase was made to accommodate Public Works GBAMS asset software. Domain values for the geodatabase was made by interpolation and discussion between Public Works, Engineering, and GIS.

This collection-level metadata provides a general description of historic Iowa coal mine maps scanned and stored as color (24-bit) TIFF images. The maps were usually prepared by a mining engineer and show the details of the mine workings, updated every second year. Most are blue print copies, but a few original linen maps are included in the collection. The maps are currently housed at the Iowa Geological and Water Survey. Each mapped mine site is represented by one to thirty-one maps. Multiple maps are typically sequential with updates being added biennially through the operating life of the mine. In this case, the most recent map was selected for georeferencing unless the map was unusable for any reason. Maps from Des Moines and the surrounding area were georeferenced with world files for a project supported by the Office of Surface Mining Reclamation and Enforcement in 2011-2012.

The "Map Image Layer - Watershed Boundaries" is the Map Image Layer of Watershed Boundaries. It has been designed specifically for use in ArcGIS Online (and will not directly work in ArcMap or ArcPro). This data has been modified from the original source data to serve a specific business purpose. This data is for cartographic purposes only.The Watershed Boundaries Data Group contains the following layers: DNR Catchments (MnDNR)HUC 12 Boundaries (USGS)HUC 12 IWM Group Boundaries (MPCA)HUC 10 Boundaries (USGS)HUC 8 Boundaries (USGS): HUC 8s represent part or all of a surface drainage basin, a combination of drainage basins, or a distinct hydrologic feature. There are 80 HUC 2s in Minnesota. (i.e. Zumbro (07040004))HUC 6 Boundaries (USGS): HUC 6s are areas which divide the subregions into more than 350 hydrologic accounting units. Minnesota has 17 of the nations hydrologic accounting units: Northwestern Lake Superior (040101), St. Louis (040102), Southwestern Lake Superior (040103), Mississippi Headwaters (070101), Upper Mississippi-Crow-Rum (070102), Minnesota (070200), St. Croix (070300), Upper Mississippi-Black-Root (070400), Upper Mississippi-Maquoketa-Plum (070600), Upper Mississippi-Skunk-Wapsipinicon (070801), Iowa (070802), Des Moines (071000), Upper Red (090201), Lower Red (090203), Rainy (090300), Big Sioux (101702), Missouri-Little Sioux (102300).HUC 4 Boundaries (USGS): HUC 4s are geographic subregions which are drained by a river system, a reach of river and its tributaries in that reach, a closed basin, or a group of streams forming a coastal drainage areas. Minnesota has 12 of the nations 222 subregions: Western Lake Superior (0401), Mississippi Headwaters (0701), Minnesota (0702), St. Croix (0703), Upper Mississippi-Black-Root (0704), Upper Mississippi-Maquoketa-Plum (0706), Upper Mississippi-Iowa-Skunk-Wapsipinicon (0708), Des Moines (0710), Red (0902), Rainy (0903), Missouri-Big Sioux (1017), Missouri-Little Sioux (1023).HUC 2 Boundaries (USGS): HUC 2s are geographic regions which contain the drainage of a major river or a series of rivers. Minnesota has 4 of the nations 21 regions: Great Lakes (R04), Upper Mississippi (R07), Souris-Red-Rainy (R09), and Missouri (R10).These datasets have not been optimized for fast display (but rather they maintain their original shape/precision), therefore it is recommend that filtering is used to show only the features of interest.

The Location Facility feature class is one of 20 essential (critical) facility feature classes developed for and maintained by the Des Moines Area Regional GIS for the purpose of performing hazard risk assessments and loss estimation using GIS. The data is also appropriately used in preparing hazard mitigation plans, emergency response plans, and general maps. The data is not compatible for direct use in HAZUS-MH (www.fema.gov/hazus) but may be extracted and converted for use in HAZUS-MH using the Comprehensive Data Management System (CDMS) tools. Used in HAZUS-MH, the data provides a basis for estimating the damage to and resulting loss of functionality of essential facilities in a given flood, hurricane, and/or earthquake scenario. Thereby, the HAZUS-MH user can model the economic and physical impacts of a flood, hurricane, and/or earthquake scenario.

This is a polygon feature data layer of United States National Grid (100m x 100m polygons ) constructed by the Center for Interdisciplinary Geospatial Information Technologies at Delta State University with support from the US Geological Survey under the Cooperative Agreement 07ERAG0083. For correct display, please set the base coordinate system and projection such that it matches the UTM zone for which these data were constructed using the NAD 83 datum. Further information about the US National Grid is available from https://www.fgdc.gov/usng and a viewing of these layers as applied to local geography may be seen at the National Map, https://www.nationalmap.gov.

This data set is a complete digital hydrologic unit boundary layer to the Subwatershed (12-digit) 6th level for the State of Iowa. This data set consists of geo-referenced digital data and associated attributes created in accordance with the "FGDC Proposal, Version 1.0 - Federal Standards For Delineation of Hydrologic Unit Boundaries 3/01/02"(http://www.ftw.nrcs.usda.gov/huc_data.html). Polygons are attributed with hydrologic unit codes for 4th level sub-basins, 5th level watersheds, 6th level subwatersheds, name, size, downstream hydrologic unit, type of watershed, non-contributing areas and flow modification. Arcs are attributed with the highest hydrologic unit code for each watershed, linesource and a metadata reference file.
