## What is TerraFlow Mobile?

Capture underground utilities, poles, and surface assets at RTK-level accuracy. One tap. Every attribute. Done.

TerraFlow Mobile connects to any GNSS/RTK receiver you already own. No locked-in hardware. No adapters. No workarounds. Your equipment works.

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.

BUILT FOR THE FIELD
→ Works with any RTK/GNSS receiver (vendor-neutral)
→ Centimeter-level positioning when your gear supports it
→ Offline-capable for areas with no cell coverage
→ Field sketching directly on the map
→ Auto-syncs to Data Engine when you're back online

YOUR DATA GOES SOMEWHERE

TerraFlow Mobile connects directly to Data Engine, the back-office platform that processes, validates, and delivers your field data. What you collect in the morning is ready for QA by afternoon.

No emailing CSVs. No USB drives. No re-keying coordinates into a second system.

Used by locators, surveyors, and field crews across utilities and pipeline operators globally.

Supports utility locate sets from Radiodetection, Vivax - Metrotech and Rycom

Sketch Management tools within the supporting Data Engine environment can be leveraged to visualize captured information and draw in offset data, buildings, notes and other reference data.

Trimble, Eos, Bad Elf, Juniper and other receivers are supported through the location system.
