Directory Structure and File Naming

GeoOps Incident Directory Structure

At the heart of all GISS work is the NWCG Standards for Geospatial Operations (GeoOps), PMS 936, Incident Directory Structure.

The Current Incident Directory Structure download contains all the essential folders, templates, and tools. It should be the default starting point for every incident.

The incident folder should be placed at or as close to the drive root as possible. This reduces clicks necessary to access items within, as well as keeps the file path as short as possible.

Eg C:\2020_Incidents\2020_ExampleFire\

Current Incident Directory Structure (zip file)

Implementing the Incident Directory Structure can be as simple as extracting and saving the YYYY_[template] folder to your computer and rename it for the incident. A GISS can extract and begin populating the directory structure even prior to arriving at the incident. The current Event GDB and Layer files are already present in the template file structure under \tools.>

Configure the Pro Project Template

There are some additional steps required to prepare the Pro Project Template to work within the structure.

Complexes

When assigned to a Complex, only a single Incident Directory Structure should be used, not separate structures for each fire.

This is the name you would use for the IncidentName attribute.

The complex name and ID should be used in all file names.

Eg. 20180805_1430_Mendocino_Cpx_CAMEU_008674_gps_ranch_flin_llw84.shp sit_river_archE_port_20180819_2130_Mendocino_Cpx_CAMEU_008674_0820day.pdf Is this right?

File Naming

The GeoOps file naming and directory structure are designed to serve as metadata. The file and folder names include incident-specific identification information which facilitates archival and use by the hosting agency, GACCs, etc.

File names must be complete and stand on their own outside of the file structure. File names must be concise, use clear text, and avoid ambiguous terms.

The general format for file naming is: {date and time}_{incident information}_{other information}; however, this will vary depending on the file in question. It is strongly recommended that all GISS use the GeoOps File Namer for consistency and accuracy on all file names.
