Complete Topographic Package

Everything you need for site analysis and design

Bare Earth (DTM)

Advanced algorithms filter out vegetation and structures to reveal the true ground surface. Essential for accurate elevation modeling.

Precise Contours

Generate contour lines at any interval (1ft, 2ft, etc.) for clear visualization of elevation and slope across your site.

3D Breaklines

Meticulously drafted along critical features like ridges, valleys, and edges to ensure hydrologically correct surface models.

Enhancement Options

There are additional add-ons available when ordering ROCK Surveyor. You can order Breaklines over selected areas of the dataset for enhanced accuracy over sharply changing terrain.

Breaklines Add-on

Enhanced contour accuracy with professionally drafted breaklines. Order breaklines over selected areas of your dataset to improve precision in sharply changing terrain (e.g., edges, ridges, drainage).

Strip Alignment

Precision alignment of multiple flight strips for increased overall point cloud accuracy

Sample Accuracy Report

This report compares your ground control points (GCPs) and checkpoints to the surface model generated from the ground‑classified points (DTM). While many tools only compare control to the raw LiDAR points, ROCK goes a step further by validating against the generated surface itself — the deliverable that ultimately matters for design.

You’ll see per‑point residuals, overall statistics, and clear pass/fail indicators so you can quickly gauge if the deliverable meets your accuracy requirements.

Data Quality Assessment

Detailed assessment of dataset quality including trajectory statistics, control checks, reprojection settings, orthomosaic and more. This report gives you confidence that your data collection and your deliverables meet survey-grade standards.

Think of it as having your own expert analyze every step of your collection: flight planning, LiDAR boresight, acquisition settings, flight height and speed, LiDAR colorization, point density under vegetation, trajectory processing statistics, orthomosaic quality, projection/CRS information, and more. It’s the most cost‑effective way to build confidence in your acquisition before moving to design.
