The portion of this repository has undergone a significant refactor in the v3.0 release to better support long‑term maintainability and multiple NENA NG9-1-1 GIS Data Model versions. What began as a single, monolithic structure has been reorganized into a clearer, modular layout that separates core schema definitions from vendor‑specific tooling and prebuilt deliverables.
To make the project easier to navigate and to streamline future updates, the repository is now organized into the following directories:
- prebuilt_templates – Ready‑to‑use File Geodatabase (FGDB) and GeoPackage (GPKG) templates generated from the NENA schema, organized by version subfolders.
- schema – The canonical, versioned logical schema definitions that drive all template generation, organized by version subfolders.
- vendor_arcgispro – ArcGIS Pro–specific example code.
- vendor_qgis – Placeholder for future QGIS‑specific example code.
This structure provides a clean foundation for contributors, tool developers, and public safety GIS practitioners who need a consistent, version‑aware implementation of the NENA NG9‑1‑1 GIS Data Model.
- prebuilt_templates - The prebuilt_templates folder contains the NENA NG9-1-1 GIS Data Model pre-built templates in sub-folders by version.
- schema - The schema folder contains the NENA NG9-1-1 GIS Data Model schemas in sub-folders by version.
- vendor_arcgispro - Folder containing example template-generation code for Esri's ArcGIS Pro.
- vendor_qgis - This folder currently serves as a placeholder for future QGIS template‑generation code.
- README.md - This document.
