Which Survey Method Fits Your Project?

Choosing the wrong survey method for a site is a common and expensive mistake. RTK GPS struggles under dense tree cover. Total Station is precise but slow across large open areas. Drone LiDAR is fast over large areas but overkill for a small plot boundary. This tool walks through the three variables that matter most and gives an instant recommendation based on how survey teams actually decide in the field.

Why These Three Factors Decide the Method

Area size determines whether the time saved by aerial methods justifies mobilization cost. Sky obstruction determines whether GNSS signal quality will hold up, since LiDAR and Total Station don't depend on satellite visibility the way DGPS RTK does. Point density determines whether you need a handful of accurate coordinates or a dense surface model of every contour and edge.

Method	Best Area Size	Sky Requirement	Point Density
DGPS RTK	Small to Medium	Open sky needed	Sparse, targeted points
Total Station	Small	Works anywhere, line of sight	Sparse to moderate
Drone LiDAR	Medium to Large	Works under canopy	Ultra-dense
Drone Photogrammetry	Medium to Large	Needs visible ground	Dense, visible surfaces only

When the Answer Is "More Than One Method"

Many real projects use a blend: DGPS RTK for control points, Total Station for dense urban stakeout, and drone LiDAR for the overall corridor. A transmission line survey through forest is a textbook case, LiDAR for the forest section, RTK for open ground, and ground control points tying everything to one coordinate system.
