Precision Surveying.
Delivered On Time.
Southline Surveying & Mapping delivers boundary, ALTA/NSPS, construction, pipeline and topographic surveys plus UAV and LiDAR mapping, with a Professional Land Surveyor on every project from first contact to final seal.
A Licensed Surveyor You Can Actually Reach
Southline is a professional land surveying and mapping firm serving the great state of Texas and its surrounding states. Every project is run by a Professional Land Surveyor who reviews the records, oversees the fieldwork and signs the plat.
We serve homeowners who need a lot survey before a fence goes up, builders who need corners set this week, title companies and lenders who need a clean ALTA, and energy and infrastructure clients who need thousands of acres mapped to a defensible standard. Different scales, same standard of care.
