Transition from ArcIMS to ArcGIS Server - IMPORTANT

Since about 2002 the North Dakota GIS Hub has had web services based on ArcIMS. The transition to production web services based on ArcGIS Server began in early 2010 and will be dramatic during 2011. If you have been or a user of ArcIMS web services it is important that you continue to read this section.

How do you know if you are a user of ArcIMS web services?

  1. Open up your ArcMap MXD files and view the source on the layer(s).
  2. If any of your ArcGIS Desktop data connections show the Internet Server to be http://web.apps.state.nd.us and/or a Feature Service beginning with “fea_”, “ras_”, or “ndwms_” then you are a user of ArcIMS web services.
  3. Note that there are a number of other ArcIMS-based web services that are generally reserved for applications but these do not begin with one of the three prefixes.

Why is this transition being made?

  1. Version 10 of the ArcGIS server products was the last release of ArcIMS
  2. We can continue to use ArcIMS but some of its functionality will be removed by Esri to allow it to co-exist with ArcGIS Server
  3. The ArcIMS-based web services are no longer maintained, e.g., new data is not added

What is the estimated time table of this transition?

  1. A distinction has been made between web services used for applications and standalone web services. Standalone web services include those with names beginning with “fea_”, “ras_”, or “ndwms_”
  2. Web services used for applications will be shut down as those applications are updated; no exact time frame has been set though by early 2012 most if not all should be gone.
  3. Web services with names beginning with “fea_”, “ras_”, or “ndwms_” will be shut down shortly after March 15, 2011.

How can I make the transition easier?

  1. Modify your project files to use the new services prior to the shutdown date to make the conversion easier and to give yourself time to become more comfortable with the new services
  2. Become familiar with navigating the REST interface and finding and using the services
  3. Review the table below to help match the new services with the old ones
New Service Name(s) Old Service Name(s) Comment
All_*(WMS) NDWMS_GeneralInfo NDWMS_GeneralInfo is used for WMS; the data in this service is replaced by multiple services which begin with “All_” and having WMS capabilities
All_*(WMS) NDWMS_aerialimages NDWMS_aerialimages is used for WMS; the data in this service is replaced by multiple services which begin with “All_” and having WMS capabilities
Features/* (WFS) and All_* (Esri) Beginning with “fea_” The “fea_” services stream vector data. Use either the “All_” services which are already symbolized or use the WFS capabilities of the services within the Features folder if you wish to symbolize the data.
All_* (WCS, WMS, Esri) Beginning with “ras_” The “ras_” services stream raster data. Use either the “All_” services in Esri format or use the WMS/WCS capabilities of the “All_” services. WMS for ArcGIS Desktop is probably not all that useful.

Can you show me some examples of converting from the old WMS to the new WMS?

  1. The conversion will include the use of new URLs, examples shown in the table below
  2. The conversion will dictate the need to use different layer IDs which are obtained from the capabilities file
  3. There are two old WMS services that need to be converted:
Old Service Name: NDWMS_GeneralInfo
Old Capabilities: http://web.apps.state.nd.us/wmsconnector/com.esri.wms.Esrimap/NDWMS_GeneralInfo?request=getcapabilities&service=WMS&version=1.3.0
New Service Name: There are now multiple WMS services instead of just one service. For example, in the old service you would find “Bedrock Geology”. The new service NDGISHUB_WMS_All_Geology contains “Bedrock Geology”.

As another example, to use county boundaries, you would use the new service NDGISHUB_WMS_All_GovtBoundaries which contains “Counties”.

To find important information regarding the new WMS services please visit this page
New Capabilities: There are now multiple WMS services instead of just one service for a specific data type so therefore there will be multiple capabilities files.

For a list of capabilities you can visit this Hub Data Portal page

Old Service Name: NDWMS_aerialimages
Old Capabilities: http://web.apps.state.nd.us/wmsconnector/com.esri.wms.Esrimap/NDWMS_aerialimages?request=getcapabilities&service=WMS&version=1.3.0
New Service Name: NDGISHUB_WMS_All_Imagery
