ArcGIS Server capability. Open standards underneath.
Built on open OGC standards from a PostGIS backbone. The built-in maps need no ArcGIS license to show live winter-operations status.
The mapping services part of this platform - dynamic vector tiles and OGC API Features - are also made available in ESRI formats (FeatureServer and StreamServer).
What SnowOps publishes - and the ESRI service it replaces
| SnowOps service | Open standard | ESRI equivalent | What it serves |
|---|---|---|---|
| PG_FeatureServ | OGC API Features | ArcGIS FeatureServer / MapServer | Queryable feature layers - zones, vehicle positions, public reports, status feed (GeoJSON). |
| PG_TileServ | OGC API Tiles / MVT | ArcGIS Vector Tile Server | Mapbox Vector Tiles on the fly from every PostGIS geometry table - road networks, districts, dense live positions. |
| Live vehicle stream | WebSocket / SignalR | ArcGIS StreamServer / GeoEvent | Sub-second vehicle-position push - no polling; 30-min history snapshot on connect. |
| AVL ingestion | OGC Moving Features | Proprietary AVL connectors | Inbound positions via MF-JSON + GTFS-Realtime VehiclePositions. |
| Sensor ingestion | OGC SensorThings | Proprietary SCADA / RWIS | Stationary IoT observations - pavement temp, friction, precipitation. |
Why this matters
Open standards mean you're never locked in. Any OGC-compliant client - QGIS, OpenLayers, a custom app - can read SnowOps data. And because SnowOps also publishes ESRI-equivalent REST endpoints, your existing ArcGIS tools can read it too, without an ArcGIS Server license of their own.
No ArcGIS license required
The built-in public and staff maps render live status from PostGIS - no ESRI licensing needed to view.
Standards-native
OGC API Features, OGC API Tiles, SensorThings, Moving Features - the same standards your GIS team already knows.
Two-way ArcGIS interop
Publish ESRI-equivalent endpoints and consume your private FeatureServer layers via the GeoLibre ArcGIS Bridge.
From the design docs
“The built-in maps … need no ArcGIS license to show live winter-operations status.”
“OSRM + Vroom - the open-source analog to ArcGIS Network Analyst, with no per-vehicle licensing.”
“Route-adherence … is the open-source analog of the coverage analysis that ESRI's Winter Weather Operations solution performs via Network Analyst + ArcGIS Velocity.”
Connect any client
Standards-based, license-free, interoperable
