OnStation vs. Field Maps
“Not everyone in the field has access to a GPS rover. With OnStation, you can verify your location with your phone.”
OnStation starts with the location, providing live station/offset and location-based documentation, ideal for field use. Field Maps is a GIS asset management tool that manages complex datasets but lacks specialized stationing functionality.
What’s the
main difference?
OnStation
LIVE STATION OFFSET IN THE FIELD
Real-time GPS Stationing: Instantly know your location on the jobsite in reference to station, mile marker, lat/long, LRS.
Document Field Data: Capture photos, notes, flags, and complete forms from the field with station/offset reference.
As-builts Verification: Mark work progress, completion, log test results, and flag issues with time, date, and station stamped location.
GIS Integration: Streamline the creation of as-built documents and export GeoJSON files for GIS systems.
Field Maps
GIS-Based Mapping & Data Collection
Map-Driven Navigation: Display GIS layers and maps with asset information (no station reference).
Data Collection & Editing: Add, edit, and update GIS features (points, lines, polygons).
Forms and Attributes: Collect detailed data through custom forms.
Advanced GIS Integration: Fully integrates with ArcGIS Pro, ArcGIS Online, and Enterprise.
If you need long-term GIS management or asset tracking, using both OnStation and Field Maps together can be beneficial.
