Although both belong to the geospatial industry, GIS and surveying have different tendencies in the selection of equipment for point surveying work. GISers are more concerned about the compatibility with GIS software and the portability of equipment, while surveyors pay more attention to the accuracy and measurement-related performance.

The NTRIP protocol is no stranger to surveyors, which consists of NTRIP Client, NTRIP Caster and NTRIP Server. During our daily surveying tasks, what we used most frequently is NTRIP Client (rover) and NTRIP Server (base). Today let’s talk about NTRIP Caster.

Nowadays, more and more farmers or surveyors want to set up a continuous operation base station for their rovers working in a specific area, such as auto-steering systems in a farm field or GNSS receivers in a construction site.

The total station integrates the functions of angle measurement, distance measurement and height difference measurement, and has three modes of angle measurement, distance measurement and coordinate measurement. It is one of the most practical and functional measuring instruments.

With the development of the surveying industry, the mainstream surveying instruments on the market mainly include two types, one is the representative of traditional optical surveying - total station, and the other is the representative of emerging satellite-based surveying - GNSS RTK receiver.

Engineering surveying technology refers to the general term of various surveying theories, methods and technologies used in the survey and design, construction and management stages of engineering construction. The service fields of traditional engineering survey technology include construction, water conservancy, transportation, mining and other departments, and its basic contents include mapping and lofting two parts.
