Event Layer Files

For a refresher on layer files, please see the GIS Concepts Review document.

The Event Layer Files can be found in the \tools folder in the GeoOps Incident Directory Structure.

Nearly every map is going to start with the Event Group All Layers 2021.lyrx file, the primary two types being the Edit Project and Incident Maps. The key difference between these two is the database to which the layer file path is repaired.

It is very important to keep these two separate because incident maps should never be created using the Offline Copy and data edits should never be made outside of the Edit Project.

Keeping the Edit Project separate from Incident Maps is a crucial component of the GISS Workflow and proper layer file management is essential to this.

A layer file stores symbology, labeling, and Feature Templates and can be used to quickly create projects. Layer files also store files paths and can easily add the wrong data to a project resulting in inaccurate products or wasted time editing the wrong database.

Following best practices will avoid any mishaps, but it is always important to be aware of what data you are working with and how all your databases, maps, projects, local copies, and layer files all fit together.

The Event Layer Files

  • Accountable Property 2021.lyrx – Symbology for the Accountable Property feature class.
  • Event Group All Layers 2021.lyrx – Point, Line and Polygon layer with point labels set up in Label Classes that can be easily converted to annotation.
  • Event Group BAM Large Symbols 2021.lyrx – Point and Line symbols sized appropriately for a BAM. Increase or decrease the size as necessary.
  • Event Group IR 2021.lyrx – Symbology for the IR feature classes.
  • Event Group Repair Status 2021.lyrx – Group layer with EventPoint and EventLine symbolized based on the RepairStatus field. This layer file should be used in conjunction with the Event Group All 2021 layer file to provide a Repair Status “halo” for features.
  • Event Line Collector Display 2021.lyrx – Simplified line symbology for use in Collector.
  • Label Points 2021.lyrx – New feature class to store labeling information.
  • Structure Triage 2021.lyrx –Structure Triage symbology based on the guidelines in the Incident Response Pocket Guide page 14+15. Alternate Triage categories for California’s FIRESCOPE are included in the data but not provided as a layer file.

Edit Project

It is recommended to use the standard Event symbology instead of the simplified symbols of the service for editing.

To do so, repair the path of the Event Group - All Layers 2021 to point to the Offline Copy (Mobile Geodatabase) (must be done layer by layer the first time in the Edit Project).

Remove the GISS Edit Service (National Incident Feature Service 2021) group to avoid confusion.

Incident Maps

Starting from the Pro Project Template.

  1. Use Save As to save the template as a new project in the projects folder, naming it per GeoOps {mapType}_{year}_{incidentName}_{localIncidentID}.aprx.
  2. Open the existing map view {MapType}_2021_{IncidentName} and rename it with the map type and the incident name.
  3. Repair the data source for the existing layers (or add the Template lyrx file and repair) to the Master Incident GDB.
  4. Open or create a Layout in the appropriate size and customize it to the product type.
