Good spatial control is absolutely critical. I have decades of experience with total station and GPS surveying, and can ensure that your projects have the highest accuracy possible so that your results are well-supported and your reports are unassailable.
Whether planning trenches in GIS or physically joining you in the field, I can help you place your trenches with the greatest ease and accuracy.
From point proveniencing artifacts or documenting historic structures, I can do total station mapping with the ShootPoints software I developed (or train your team to do so themselves), to quickly and accurately generate maps of your work.
