GIS and assets.

Asset types

• Outfalls.
• BMPs (best management practices), including structural BMPs.
• Sites (parcels, facilities, properties).
• Drainage structures.
• IDDE incidents (illicit discharge cases).
• Sample locations.

Interactive basemap

The workspace map ships with street, topographic, and satellite basemap options. An inspector panel shows parcel info and related records. On-map filters narrow features by status (for example, overdue inspections, open IDDE cases, BMPs missing recent inspections) so the daily queue can be worked from the map view.

Import and export

Spatial layers can be imported as GeoJSON or shapefile. CSV with lat/lon works for point assets. Records export as CSV, JSON, and GeoJSON on every tier. WGS84 is the standard coordinate system; original GIS file uploads are preserved separately from the optimized display layer.

ArcGIS and QGIS coexistence

NPDESTracker is designed to coexist with ArcGIS Online, ArcGIS Enterprise, and QGIS. We do not claim to replace your enterprise GIS and we do not claim a partnership with Esri. The export formats and WGS84 standard are chosen so layers can move between NPDESTracker and your existing GIS without translation drama.

Browser GPS on inspection creation

When the inspector creates an inspection in the field, the browser can capture the device's current location and attach it to the inspection record. The inspector confirms the location before saving. Location attribution lives on the inspection record itself, not as a separate tracker.
