In the ever-evolving world of surveying and geospatial data collection, technology continues to push the boundaries of what is possible. Two technologies that have made significant advancements in recent years are drones and Real-Time Kinematic Global Navigation Satellite Systems (RTK GNSS). These technologies have revolutionized the field of surveying, but a pressing question remains: can drones replace the role of RTK GNSS in surveying? Real-Time…

OTIC Surveys was well represented and had a successful exhibition.
GNSS OR TOTAL STATION FOR A TOPOGRAPHIC SURVEY A topographic survey is considered the first step in any construction or developmental project. It is very crucial for planning, design, and construction as it forms the basis of the architect’s design and enables them to accurately design their projects to be tailored down to their client’s specifications or needs and the unique features of the land.…
