Where can I find more information on how to get the LSIS into an ArcIMS project?
You may add the LSIS as an internet map service. Internet map services stream live data to the ArcIMS project. Use http:/www.geocommunicator.gov as the server name, and BLM_LSIS as the service name. Through the Add Data dialog window in ArcIMS, choose Add Internet Server. From the Add Internet Server dialog window, type in the URL of server: http://www.geocommunicator.gov and choose BLM_LSIS from the list of services.
