Welcome to the Indiana Spatial Data Portal (ISDP)

The Indiana Spatial Data Portal (ISDP) provides access to Indiana geospatial data. Most datasets are available to the public for download and have no use restrictions. Indiana University’s (IU) high performance networks and computing infrastructure support the ISDP which archives and provides web access to imagery provided by data partners within and outside IU. To learn more about discovering, downloading and viewing data from the ISDP, please visit the 'About' page.

Available statewide datasets include aerial photos, topographic maps, LiDAR and elevation data, and Sanborn historic maps. In addition, the ISDP hosts several local datasets for Allen, Bartholomew, Boone, Dearborn, Gibson, Hamilton, Hancock, Hendricks, Johnson, Marion, Monroe, Morgan, Posey, Shelby and Wayne Counties.

This web site connects to Indiana University's Scholarly Data Archive (SDA) which provides long-term, disaster-tolerant data archival and distribution capabilities to hundreds of terabytes of IU data. The SDA archives data on tapes. When downloading files, you will receive an email when your download is available. Please be aware that there will be a delay between requesting the download and receiving the email that, depending on the size of the file, could range from a few minutes to several hours. During this time a robotic system is locating and mounting a tape and transferring your file from tape to spinning disk.
