In addition to the wide variety of data available for download via the online catalog, DASC has built online services that can be used with web and desktop applications over the internet.

This functionality is particularly useful with aerial imagery and raster data. In terms of file size, imagery files are some of the largest entries in our catalog, yet they are some of the most popular. Using ESRI's ImageServer and ArcGIS Server software, you can now access state-wide aerial imagery for multiple years, as well as some high-resolution county imagery.

DASC also provices some vector data as map caches, both tiled and dynamic. All these services can be used with DASC's web mapping application or within ESRI's ArcMap application.

In ArcMap v9.3 and later, you can add our ImageServer services to your map like any layer.

To connect to DASC's ArcGIS ImageServer data, open ArcMap:

Click on the Add Data button, and set the Look in: menu option to GIS Servers:

Double-click on Add ArcGIS Server:

Select Use GIS Services and click Next:

Enter http://giselle.kgs.ku.edu/arcgis/services as the Server URL and click Finish:

This will create an ArcGIS Server connection called arcgis on giselle.kgs.ku.edu. Double-click on the connection name to connect to the server. Once connected, you will see a list of folders and map services available from the server:

Navigate into the ImageServer folder to see a list of the available image services. Double-click on any of the service names to add it to your ArcMap project:

The imagery will load as a layer within ArcMap:
