TopoMatters | Aerial LiDAR and Data for Surveyors

TopoPro® LiDAR Processing

Post processing that's purpose-built for US land surveyors.

7 Parameter Helmert Transformation for Drone Mapping

Start with localized and classified point cloud tiles

TopoPro imports point cloud tiles in ground-scaled project coordinates, preserving and respecting existing ground classifications for precise and seamless integration.

Scalable tile processing

Point clouds can be unwieldy due to their size. TopoPro efficiently processes LAS tiles one at a time while indexing adjacent tile data to ensure seamless conformity across boundaries.

Smart thinning

Streamline your point cloud with TopoPro’s advanced smart thinning algorithm that selectively cuts redundant points from the dataset.  The best ground points are preserved to achieve the target point cloud density.

Vertical bias adjustment

Aerial LiDAR scans often exhibit systematic vertical bias. TopoPro identifies and adjusts the Z-bias using project control, ensuring both ground and off-ground points align perfectly with the survey’s vertical control.

Clip to survey limits

Presentation matters. TopoPro clips the processed point cloud to your survey limits (plus a buffer), ensuring polished and professional results—all in your project’s coordinate system.

Point cloud quality reporting

Using ASPRS-based methodologies, TopoPro validates data conformance against check shots. Detailed reports include vertical RMSE, deltaZ for individual shots, and alerts to quickly flag outliers for review.

Grade break computing

Identifying grade breaks across a large survey area can be challenging. TopoPro simplifies this by using advanced algorithms to extract grade breaks from the point cloud with direct integration into surface models.

3D breakline enforcement

Client-provided LandXML breaklines are enforced in TIN surfaces, preserving sharp edges and the integrity of ground features. Don’t have breaklines? TopoMatters can extract breaklines directly from the post-processed LAS.

Topo/TIN and terrain fit reporting

Enjoy high-quality surface derivatives, including contour (.DXF) and TIN (LandXML & .DXF) surfaces. Terrain models are tested against 1,000 random LAS points, measuring the number within a defined conformance tolerance.

Processing Transparency with Interactive Quality Report

Say goodbye to black-box processing. TopoPro’s interactive HTML report provides a step-by-step breakdown of LAS treatments and derivative extractions, complete with applied parameters, QC and 3D visualizations.

Working with unscaled or unclassified data?

Have an LAS file in state plane coordinates? TopoPro can ground-scale your data with confidence. Need ground classification? TopoPro does that too.
