For a refresher on how to use the streaming web services on the GIS Hub, which allows you to use data without downloading it, please visit http://www.nd.gov/gis/mapsdata/web/. In the section titled, "ArcMap - ArcIMS Web Services" you will find information how you can stream both image data such as aerial photography and vector data such as roads. In the sections referring to "OGC Web Map Services (WMS)" you will find information on how you can use a web service with both ESRI and non-ESRI software.
