Will there be an impact of photogrammetry on terrestrial surveying?
A There have been several advances in the techniques and equipment used for photogrammetric surveying in the last two decades. The advent of high quality digital cameras and incorporation of GPS receivers on aircraft are just two. One thing that has traditionally been the domain of the terrestrial surveyor has been the coordination of discrete points used to rectify aerial photography and satellite imagery. This coordination aspect is likely to continue for some time yet, however low cost GPS based products such as our Sokkia Stratus product are proven to be ideal for this function. The attraction in the marketplace has been the affordability, ease of operation and quick turnaround time. The quality of data available from remotely sensed sources had advanced at such a rate that, yes, there is likely to be a significant impact on certain aspects of a terrestrial surveyor’s business. However, both systems will continue to compliment each other in some areas. Q. Will Sokkia products expan
