Earth's Largest Land Surveyor Community
One of my clients asked me to make a detailed survey in the area shown in the attached picture. They want to understand how the elevation varies at the site, in order to make a precise calculation of the excavation volumes needed for some environmental remediation activities.
Apart from LIDAR, which I am considering but that I would like to avoid, can some of you give me any suggestions on how to make a traditional survey under quite a thick tree canopy? Each time I have tried making GPS surveys under the trees, I always got poor results and carrying out a decent survey was nearly impossible.
Many thanks in advance,

You can do a total station survey. And be sure to set up many control points with GPS static any where possible on the open ground so that you have lots of place from where you can survey. And if there are no small bushes in between the trees it should be a piece of cake.
I'll send you a sample work
