- DNR Data Deli: Allows users to download selected geospatial data files, with accompanying documentation. The Data Deli, from the Minnesota Department of Natural Resources, is an internet-based spatial data acquisition site that allows users to download raw computer-readable data for use in their Geographic Information System (GIS), image processing system, or traditional database environment. The site includes links to extensive and summary level data descriptions (metadata) to support our users. (Remote application)
- IFSAR: IFSAR technology maps large areas more quickly and more efficiently than any other technology in the world. A fixed-wing aircraft, equipped with IFSAR, can operate day or night, in clear or cloudy conditions— virtually anywhere, anytime.
IFSAR is advanced, flexible, and capable of handling a high volume of data. This means it is less expensive than competing technologies, while still providing you with highly-accurate (+\- 1 Meter) digital elevation products that can enable a wide range of innovative applications.
Intermap’s IFSAR systems use two antennas separated by an interferometric baseline to image the earth’s surface by transmitting radar pulses toward the terrain. The reflected energy, represented by the lines from the two antennas to the terrain below,is recorded by both antennas, simultaneously providing the system with two SAR images containing amplitude and phase of the same point on the ground, separated only by the phase difference created by the space between the two antennas. In addition, as the aircraft passes over the terrain, global positioning system (GPS)
data from both aircraft- and ground-based GPS devices and navigation data from an Inertial Measurement Unit (IMU) onboard the aircraft are collected.
The phase difference between the antennas for each image point — along with range, baseline, GPS, and navigation data — is used to infer the precise topographic height of the terrain being imaged. This enables us to create an interferogram (depicting the phase difference) from which we derive our DSMs and ORIs. Through additional processing, we generate our DTM and CORI products.

- MetroGIS DataFinder WMS: DataFinder offers 18 WMS containing over 150 datasets total. The layers in the WMS are organized into the same categories as the DataFinder Catalog. While OGC Capabilities files are available for WMS and WFS, these contain only basic information. To understand which layers are in each map service and relate the dataset name to its metadata record, please use the DataFinder Catalog together with the WMS webpage. (Service)
- Minnesota Geology: This is a map service containing GIS layers that fall in the category of Geologic features. Currently this consists of geological features. The link below will return the GetCapabilities document which has the information necessary to use this service.
- What's In My Neighborhood? - Agricultural Interactive Mapping: This interactive mapping application allows you to view known and potential sources of agricultural chemical soil and ground water contamination. The inventory includes properties that have already been investigated and cleaned up, as well as those currently enrolled in MDA cleanup programs. Users can search for specific site locations, conduct searches by options such as city, county or zip code, and print maps of site locations. (Remote application)
