GPS technology is the wave of the future in land surveying.
The field of surveying is continuously changing. Technological advances make this profession a moving target. But you can stay on top of your game with PDH online courses.
One of the most groundbreaking developments in recent years has been GPS technology. Using GPS equipment for land surveying makes the job infinitely easier and faster. One reason is that it is no longer necessary to set up survey stations within sight of each other. As long as a station can receive signals from four satellites, its location can be pinpointed without the need to measure distance between stations.
According to GPS.gov, GPS technology was originally developed for the military, but one of its first civilian uses was for land surveying. They note that today, the technology is also used to map waterways by pairing it with sonar equipment.
GPS Has Certain Limitations
As magical as GPS technology sometimes seems to be, however, it has its limits. And for this reason, land surveyors still frequently need to fall back on their trusty, time-tested tools.
For example, objects such as trees, tall buildings, and land formations can get in the way of GPS signals. In these instances, land surveyors must use their theodolites, electronic distance meters or total stations, although sometimes in conjunction with the GPS.
GPS equipment is also costly. This makes its use less common than it would be if it were cheaper, and thus, fewer surveyors have the chance to work with this equipment.
When a land surveying company considers the cost of investing in GPS equipment, they must factor in the cost of training staff in how to use it, plus the time it takes for everyone to become proficient.

Learning GPS technology is essential for land surveyors.
