WHAT YOU CAN MAP → Underground utilities (gas, electric, telecom, water, sewer) → Poles and overhead infrastructure → Surface features and markers → Sensor and inspection data Each collection type has its own workflow built for how the job actually runs in the field. You're not fighting the app to match your process. HOW IT WORKS Tap your locate point. TerraFlow captures coordinates, depth, signal strength, and utility attributes in one shot. Add a field sketch on top of the map. Move to the next flag. Every record ties back to the ticket or work order it belongs to. Nothing gets lost between the field and the office.
