GPS Services

GPS Surveying ServicesSempco Surveying, Inc. employs the latest GPS technology, possessing multiple licenses for operation upon the Western Data Systems VRS network. Our GPS equipment is also capable of operating outside the VRS network, utilizing R8 rover units and 5800 & 5700 base units. GPS enables us to easily work within the Texas State Plane Coordinate System, collecting real-time coordinate data in the NAD 27, or NAD 83, or any datum required.


Topographic Surveying

A topographic survey may be defined as one that determines ground relief and location of natural and man-made features thereon. Performing a topographic survey requires taking shots of the natural terrain at:

• grade breaks
• along channels
• along corners and alignments of fixed works
• at brush boundaries
• other details of the natural terrain
• other man made objects

The location of trees might also involve shots at the drip line and measurements at the top of the crown.

Measurements for utility structures (poles or towers) might also involve shots at various points on the wire.

Construction As-Built's

A construction survey may be defined as one that locates points prior to, during, or after construction of a fixed work on a site. That fixed work may be a road, structure, or may involve excavation or fill of materials. Also called stake-out.

Often, a survey to check the final position of a structure is called an “as-built” survey.
