GIS Web Service Changes
Upcoming Changes to Montana State Library GIS Web Services - Immediate Attention is Required
The Montana State Library will retire its Esri Cloud Managed Services (EMCS) environment on July 31, 2026. A new cloud‑hosted environment, supported by ROK Technologies, is now available.
These changes will affect GIS applications, workflows, and map products, including ArcGIS Online items, ArcGIS Pro/Desktop projects, and web applications. Users are encouraged to review their systems and make updates as soon as possible.
All service users are strongly urged to review the linked documentation in full. It contains critical information regarding service availability, layer reference updates, schema modifications, migration requirements, and other essential changes.
After July 31, 2026 deprecated MSDI & other GIS Web Services hosted in the ESRI Cloud Managed Services (EMCS) environment will be officially retired and no longer accessible.
