With the retirement of the GeoMAC website for data hosting and public data distribution in 2019, another method of delivering incident geospatial information to the public was needed. The decision was made to use existing capabilities of ESRI's ArcGIS Online platform to meet that need. The National Interagency Fire Center (NIFC) “Open Data” site is a feature of ArcGIS Online, which creates a publicly accessible, searchable website. Open Data sites make authoritative data easy to find and access in multiple commonly used formats. Making perimeters that have been approved for sharing with the public accessible through the NIFC Open Data site has a number of key benefits:
- Users can access the data in their preferred format - shapefile, geodatabase, spreadsheet, or several flavors of web service.
- Perimeter data can be shared from the same site as other wildland fire reference data, including dispatch boundaries, Geographic Area boundaries, and predictive service areas.
- Open Data sites are cloud-hosted and scale to the load put on them, depending on traffic, reducing the cost and management workload of providing public-facing data.
The NIFC Open Data site URL is http://data-nifc.opendata.arcgis.com/ and requires no login or password.
The following data sets are publicly available through the NIFC Open Data Site. Details can be found in the description of each service on the site.
