SURFACE MAPPING
Surface mapping is the elevation capability in TerraFlow Mobile. Here the GPS receiver is the instrument. Nothing else to connect, because the thing measuring position is the thing taking the reading. How TerraFlow Mobile works
Cut and fill against design for landfills, stockpiles and surface work. Height, slope and volume measured as the work happens, with the accuracy of every measurement recorded beside it.
Cut and fill against design, live Compare the surface to your design in the field. The operator sees the difference where they're standing, not after the survey comes back.
Compliance measured, not claimed Height, slope and volume with the position accuracy recorded at capture. When a regulator asks what the surface looked like on a given date, the answer is a measurement with its conditions attached.
Day-to-day volumes on your own schedule Cut and fill volumes from the surface data you've already captured, at the accuracy your receiver delivered. Your certified surveys stay with your surveyor.
Every move of waste costs money.
On a landfill, every time waste gets moved it gets paid for twice. Getting it in the right place the first time depends on knowing where the surface is right now, not where it was at the last survey.
A backpack-mounted receiver and a tablet on the operator give you that every day, at whatever accuracy your receiver delivers. TerraFlow records that accuracy with every point, so it's always clear what a measurement can support.

"We needed a solution to fill the landfills accurately and efficiently. The more times we move waste within the landfill the higher the expenses." Colin Penniket, Project Manager, Secure Energy Services
Secure Energy Services case study
Landfill operators Airspace, daily and interim cover, capacity reporting and closure conformance, measured every day, between the periodic surveys.
Aggregate and stockpile operations Day-to-day volumes on your own schedule, between contracted surveys.
Remediation programs Surface verification on long programs where thousands of points pile up over years.
Works with the receiver you already own
TerraFlow supports the accuracy your receiver supports. It adds none of its own. Every point is recorded with the accuracy the receiver reported, so you can see what each measurement can support.

Specifications
Design surface: import the design surface that sets your target elevations and slopes. As you move across the site, on foot or mounted on equipment, TerraFlow Mobile shows how much fill the space can take, or how much needs to come out to stay on design.
Capture: point, line and polygon, with per-vertex detail. Text, dropdown and radio-button attributes. Photos. The user and a timestamp on every record.
Collection methods: a single point, timed points or lines that track the user or the machine, or points the user chooses one at a time.
Accuracy information per point: the GNSS metadata the receiver reports, including accuracy and satellites.
Hardware: the GNSS receivers on the supported instruments list.
In the field: map from the captured data, and navigate back to any point.
Devices: Android and iOS.
Workflows and setup: your asset types, attributes, dropdowns and conventions, configured by us and managed through the web admin. Unlimited attributes.
Offline: works with no connection. Syncs when one returns.
Export: CSV, KML, Shapefile, ArcGIS Online and Portal, and DXF configured to your block and line standards. Import: DXF, KML, ArcGIS Online and Portal.
Deployment: hosted in Microsoft Azure with a separate database per client, or on-premises as TerraFlow Enterprise.
