What is the Indiana Spatial Data Service?
The Indiana Spatial Data Service (ISDS) is an enterprise geographic information system (GIS) designed to provide online access to aerial photos, topographic maps, and historic imagery of Indiana. The system uses an Oracle database and server-based GIS software (ArcSDE and ArcGIS Server) to output maps and data to a variety of GIS software and web browsing clients. The ISDS is hosted by UITS at Indiana University and is an application component of the Research Database Complex (RDC).
Data access methods
You can view maps and aerial photos from the ISDS in the following ways:

IU's RDC undergoes scheduled maintenance on the first Tuesday of each
month. Plan for the system to be down during business hours on this
day. The system may be sporadically unavailable at other times due to
unforeseen circumstances or software upgrades. In such instances, UITS
will try to restore service in a timely manner. If an outage occurs
over a weekend or holiday, service may not be restored until the
following business day. To receive news about ISDS, including
temporary outages and new datasets, subscribe to the ISDS news list on IU
