Earth's Largest Land Surveyor Community
I would like to start that discussion about the Open Source software RTK-LIB that allows anyone to post-process GNSS observations (RINEX) for free and also to perform RTK (RTCM).It seems UAV…Read more →
Joel van Cranenbroeck has not received any Boosts yet
Most of the GNSS Network RTK projects have been developed by the economical justification that an active geodetic network would reduce the cost of maintaining a traditional geodetic network where the maintenance of the benchmarks and the control survey were a significant part of the ownerís budget.…Read more →
When I started my career, I have been attracted by one (of many) question : how accurate is the surface/volume calculations knowing the uncertainties of the points that define these geometrical figures. I really wanted to know in term of standard deviation what would be the "end results".
The solution was to propagate the variances (standard deviation squared) into the functional model (the…Read more →
Good news for all of you who are using a GNSS RTK without the fancy tilt meter and IMU onboard !
You can turn your today GNSS receiver to do the "free bubble style" by mixing up 2 technologies that popped up last year.
The first one is about software receiver as we learnt we can feed the digital signal…Read more →
One of the typical survey method for determining station's points and survey details has been the traverse method. There have been considerable discussions on the way to "adjust" angles and distances and lot of rules of thumb while rigorous Least Squares Adjustment softwares are available anywhere.
I would say "too much" talks and controversial exchanges for a method that is simply not appropriated anymore considering modern instruments. Long traverses (geodetic) have been…Read more →
