This site provides free access to Iowa geographic map data, including aerial photography, orthophotos, elevation maps, and historical maps. The data is available through an on-line map viewer and through Web Map Service (WMS) connections for GIS. The site was developed by the Iowa State University Geographic Information Systems Support and Research Facility in cooperation with the Iowa Department of Natural Resources, the USDA Natural Resources Conservation Service, and the Massachusetts Institute of Technology. This site was first launched in March 1999.

In this research, the best management practices include vegetative/structural conservation practices (SCP) across crop fields, such as grassed waterways and terraces. This reference dataset includes 500,000 pair patches (false-color image (B1: NIR, B2: Red, B3: Green) and binary label (SCP: yes[1] or no[0]). These training samples were randomly extracted from Iowa BMP project (https://www.gis.iastate.edu/gisf/projects/conservation-practices) and present 90% of patches with SCP areas and 10% of patches non-SCP area. The patch dimension is 256 x 256 pixels at 2-m resolution. Due to the file size, the images were upload in different *.rar files (imagem_0_200k.rar, imagem_200_400k.rar, imagem_400_500k.rar), and the user should download all and merge them in the same folder. The corresponding labels are all in "class_bin.rar" file.

Application: These pair images are useful for conservation practitioners interested in the classification of vegetative/structural SCPs using deep-learning semantic segmentation methods.

Further information will be available in future.

National Weather Service Local Storm Reports from the last 24 hours are downloaded every 30 minutes from the Iowa Mesonet GIS Page and added to ArcGIS Online using the Python API. The source of the csv comes from https://mesonet.agron.iastate.edu/data/gis/shape/4326/us/lsr_24hour.csv.. LSRs can also be downloaded for a weather forecasting office of interest at https://mesonet.agron.iastate.edu/lsr/ .

dems: LiDAR DTM data partitioned into training, testing, and validation datasets based on HUC8 watershed boundaries. Original DTM data were provided by the Iowa BMP mapping project: https://www.gis.iastate.edu/BMPs. extents: extents of the training, testing, and validation areas as defined by HUC 8 watershed boundaries. vectors: vector features representing agricultural terraces and partitioned into separate training, testing, and validation datasets. Original digitized features were provided by the Iowa BMP Mapping Project: https://www.gis.iastate.edu/BMPs.

The Natural Resources Geographic Information System (NRGIS) Library is a Geographic Information System (GIS) repository developed and maintained by the GIS Section of the Iowa Department of Natural Resources (DNR). It is a collection of more than 20,000 geographically referenced databases. The purpose of the NRGIS Library is to improve the availability, integration, and analysis of natural resource information and improve decisions to carry out agency responsibilities related to the management, protection and development of Iowa's natural resources. The NRGIS Library is seen as a one-stop repository for all of Iowa's natural resource, geographic information.

This coverage contains points that represent populated places, ie. cities, towns, villages or any other named place where people live. The coverage was developed from the USGS Geographic Names Information System (GNIS) database for Iowa. There were many errors in the original GNIS data, including missing points or mislocated points. The GNIS points were compared to two reference sources: USGS 100k scale county maps and Iowa DOT county highway maps. Mislocated and missing point were fixed and each town was designated as having been verified from one or the other reference sources or both. Some GNIS points were not verified from either source and are so designated (use these with caution).

This dataset is a collection of fishing, boating, and paddling (Canoe & Kayak) access points of waters in the State of Iowa.

This imagery is provided through a project funded by the Iowa DNR in cooperation with the ISU GIS Facility. The source aerial photos for this map service were acquired by the National High Altitude Program (NHAP) from May 1981 to August 1986.

A landscape is a collection of land shapes or land forms. Landform regions are a grouping of individual landscape features that have a common geomophology. In Iowa, these regions are composed of earth materials derived from glacial, wind, river, and marine environments of the geologic past. This is a new representation of the landform regions of Iowa, at a scale of 1:24,000, and derived from a variety of sources including soils, slope maps, topographic maps

This map contains the high impact events that have occurred in northern Arizona. Descriptions of events and location information were gathered through from storm data and local storm reports from the Storm Prediction Center. Pictures were gathered from National Weather Service Flagstaff event files.Local Storm Report Data: https://mesonet.agron.iastate.edu/request/gis/lsrs.phtmlAll descriptions of events and photos property of NWS Flagstaff.

This imagery is provided through a project funded by the Iowa DNR in cooperation with the ISU GIS Facility, and USDA Natural Resources Conservation Service. These aerial photos were acquired by the US Department of Agriculture from 1936-1941.

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 coverage contains points that represent the locations of known sinkholes either from soil surveys or DNR staff field investigations

This is a coverage of the Des Moines Lobe Glacial Advances. It is mapped to a scale of 1:250,000.

The Public Land Survey System (PLSS) is a way of subdividing and describing land in the United States. This dataset contains the Townships, Ranges, and Sections of the Public Land Survey System (PLSS) in Iowa. Coordinates were digitized from U. S. Geological Survey 7.5' topographic maps (paper copies) using a digitizing program developed in-house by the Geological Survey Bureau, Iowa DNR. The digitizing tablet accuracy was 1/50 inch. Section lines from individual quads were combined and edited. Further subdivisions into Quarter sections (up to 3) were done with an ArcView Script on regular-shaped sections.
