Edits and Feedback
To submit a comment/edit to the National Boundary layers, please complete this feedback form.
While the DMP edits the data, the data stewards initiating and approving the changes include:
- 1-2 representatives from each Geographic Area Coordination Center (GACC).
- The National Wildfire Coordinating Group’s (NWCG) Geospatial Subcommittee (GSC) includes at least 2 representatives, including the past and present editors of the focus GIS data layers.
- Telecommunications is represented by at least 2 persons, including the Communications Duty Officer (CDO).
- Applications invited included IRWIN (Integrated Reporting of Wildland Fire Information), InFORM (Interagency Fire Occurrence Reporting Modules), WFDSS (Wildland Fire Decision Support System), EGP (Enterprise Geospatial Portal), and CFETS (Communication Frequencies & Equipment Tracking System).
The data stewards above comprise the National Boundary Working Group. While the National Boundary Working Group does not have a regular meeting cadence, the group will meet as required based on business needs.
