UAV, LiDAR & GIS Mapping
High resolution aerial mapping and terrain intelligence tied to survey grade control. Faster data on large sites, without giving up the accountability of a licensed surveyor.
Survey Accuracy at Aerial Speed
Southline integrates UAV photogrammetry, LiDAR and GIS into the same workflow as our boundary and topographic surveys. Ground control and checkpoints are set by our crews, flights are planned to the accuracy your design requires, and every deliverable is reviewed by a Professional Land Surveyor.
The result is data your engineers can design on, your construction team can build from, and your lender or landowner can trust.
Geospatial Services
UAV Aerial Mapping
Drone based photogrammetry for rapid, high resolution mapping of large or hard to reach sites.
- Orthomosaic imagery and site basemaps
- Photogrammetric surfaces and contours
- Construction progress and stockpile documentation
- Solar, wind and pipeline site mapping
- FAA Part 107 compliant operations
LiDAR & 3D Terrain Modeling
High density point clouds and terrain models for sites where vegetation, scale or accuracy rule out photogrammetry alone.
- Digital terrain and surface models (DTM / DSM)
- Classified point clouds and bare earth surfaces
- Contours, cross sections and profiles
- Cut/fill and earthwork volumetrics
- Accuracy reporting to ASPRS standards
High Resolution Corridor Mapping
Purpose built mapping for pipelines, transmission lines, roadways and other linear infrastructure.

How a Geospatial Project Runs
Define Accuracy
We confirm the accuracy class, coordinate system and deliverable formats your design team needs before anything is flown.
Set Control
Ground control and independent checkpoints are set with survey grade GNSS and tied to published control.
Acquire & Process
Flights are planned for the site, then imagery or LiDAR is processed, classified and checked against the control.
Deliver & Certify
Surfaces, orthos, point clouds and GIS files are delivered with an accuracy report and reviewed by the surveyor of record.
