The Global Positioning System changed the world of land surveying in many ways, most of them good. There are, however, some downsides to this type of equipment. Here is a quick summary of the pros and cons for GPS land surveying:
- It offers a higher level of accuracy than conventional surveying methods
- Calculations are made very quickly and with a high degree of accuracy
- GPS technology is not bound by constraints such as visibility between stations
- Land surveyors can carry GPS components easily for fast, accurate data collection
- Some GPS systems can communicate wireless for real-time data delivery
- GPS land surveying equipment requires a clear view of the sky to receive satellite signal
- Interference from dense foliage and other structures can limit function and communication
- All GPS survey equipment is subject to failure from dead batteries and system malfunction
- Special equipment may be required and can be costly
The world of land surveying is constantly changing as new technology replaces old. Commercial survey equipment has made leaps and bounds over the past few decades and, with the help of GPS technology, will only become faster and more accurate over time.
Used properly, GPS for land surveying offers the highest level of accuracy and is much faster than conventional surveying techniques
