Good survey techs are hard to find.
Consider TopoMatters Your Workforce Multiplier!
Shatter the traditional tradeoffs between quality, speed, and cost through replicable UAS-based LiDAR service and photogrammetry workflows.
You establish control and check points, we’ll plan and fly the mission, process the collected data, perform quality assurance against known check shots, and work with you to hand off post-processing deliverables that fit into your workflow.
Precision Data Collection - Photogrammetry and LiDAR Service
Using industrial UAS equipment with RTK and PPK corrections, our photogrammetry and LiDAR service captures data with centimeter-level precision. This can lead to remarkable outcomes when it comes to processing the survey.
In project locations where RTK is available, data is collected in the NAD83 (2011) realization. Alternatively, data is post processed with PPK and transformed to this adjustment, with final deliverables projected to State Plane, UTM or a local coordinate reference system.
5 Return LiDAR = 5 Chances to Reflect Bare Earth
Whether collecting data amongst ponderosa pines, aspen groves or a sea of sage, 5 return LiDAR is a valuable technology that can enhance the quality and utility the LiDAR data. By recording multiple returns from a single laser pulse, 5 return LiDAR can provide more information, accuracy, and versatility for various applications and analyses.

Seven Parameter Localization
Many projects require data in projected in your local coordinate system. In this case, ground control point coordinate pairs are applied to transform the point cloud to the project’s local coordinate system prior to further processing. Typically we’ll expect five pairs of coordinates in State Plane plus your local coordinate system to apply the transformation.
Bring your own ground shots
Good drone data will always be complemented by at least some ground work by the Professional Land Surveyor, including control, check shots, areas that can’t be seen from the air and of course property boundaries, monuments and utilities.
