Connecting to IGS Map Services using
Desktop GIS Software

---

Desktop GIS software users may access IGS Web map services (WMS) online without downloading GIS data sets to their local systems. This is particularly useful for viewing large aerial photo data sets that may be hundreds of gigabytes in size. Follow the instructions below to load map services directly as data layers into ESRI ArcMap or other WMS-compatible GIS software applications.

Instructions for connecting to ArcIMS services from ArcMap

1. Open ArcMap, and click Add Data.


2. In the Add Data dialog box, from the "Look In" drop-down menu, choose GIS Servers.


3. Double-click Add ArcIMS Server.


4. Enter the URL for the server (http://igsmap1.indiana.edu)


5. Choose the All Services option, and then click OK to create a new connection to the IGS server.


6. In the Add Data dialog box, double-click the new server connection to view available map services.


7. Select one or more map services, and then click Add to load the map services into ArcMap.

Instructions for connecting to Web Map Services
from WMS-compatible clients

From a WMS-compatible client, establish a connection to the map service of interest using this URL format:
[Server]/wmsconnector/com.esri.wms.Esrimap?ServiceName=[Map Service]

Replace [Server] and [Map Service] with information from the table below. For example, to connect to the Geodetic Control Framework service, use:
http://igsmap1.indiana.edu/wmsconnector/com.esri.wms.Esrimap?ServiceName=fw_geodetic_control

Note: Several of our map services include a main map service and also an index map service, which is used by our Web viewer applications. The index map services should be disregarded when viewing these services using desktop GIS software.

Additional information about IGS map services is available from the Interactive Maps page.
