Incident Command AssistantFit the incident
Search and rescue, public safety incidents, and planned events use overlapping command principles but different field details. Organizations can shape views and task flows around the work they actually perform.
See Operations →Built to be adapted
An incident platform should fit the organization using it.
ArcHorizon is planned for open-source release. Access to the code gives agencies and volunteers a path to tailor workflows, inspect how information moves, and build integrations for their own operations.
Adaptability
Keep the common picture. Change the parts that are local.
The incident record connects people, tasks, geography, and reports. An open-source foundation makes it possible to adapt the surrounding workflows without giving up that shared structure.
Use the right documents
Form profiles and field mappings can reflect the documents an agency uses, including different ICS profiles and local reporting needs.
See Documentation →Bring local data
Reference layers, public GIS services, and GeoJSON exchange let local geography and operational datasets contribute to the map.
See Mapping →Connect existing systems
Open implementation details make it easier to build import, export, and service connections around existing agency tools.
See architecture →Technical foundation
Understand the pieces before changing them.
The Windows-first desktop application uses Python and PySide6 Qt Widgets. It keeps local incident data available and can connect through a LAN server or cloud path. The companion app gives field personnel a focused view of the same work.
Geographic features can move between systems as GeoJSON. Form mappings and incident records provide other points where local needs can be expressed without rebuilding every screen.

Practical flexibility
Adapt a form or map layer without losing the incident thread.
A local form can draw on the same subject, team, task, and activity records used elsewhere. A local map layer can sit alongside assignments and hazards. The value is in preserving the relationships while changing the pieces that vary by place or agency.

Open-source release
Code access supports scrutiny and contributions.
Organizations can inspect how records connect, propose changes, and share improvements. The source repository and license will be linked here when the open-source release is published.
