NWCG Standards for Geospatial Operations, PMS 936

 

The NWCG Standards for Geospatial Operations (GeoOps), PMS 936, provides the basis for consistency in the delivery of wildfire incident GIS products and services. These standards must be adhered to for all work performed by incident Geographic Information System Specialist (GISS) to fulfill the GIS needs of the Planning Section of the Incident Management Team (IMT).

Other NWCG resources, such as job aids, checklists, and training courses, are available to develop the GISS position and to implement GeoOps. A key resource for a GISS is the NWCG GISS Workflow, PMS 936-1, a supplemental publication to GeoOps which provides the implementation instructions and documentation for the standards presented in GeoOps..

The NWCG Standards for Geospatial Operations (GeoOps), PMS 936, are developed and maintained by the NWCG Geospatial Subcommittee (GSC) under the direction of the NWCG Data Management Committee (DMC).
Prior to February 2020, these standards were known as GIS Standard Operating Procedures on Incidents (GSTOP). While previous versions may contain relevant or useful information, the GSTOP is obsolete. The user of this information is responsible for confirming that they have the most up-to-date version. NWCG is the sole source for the publication.

Comments, questions, and recommendations shall be submitted to the appropriate agency member assigned to the GSC. View the complete roster.
