THE RIGHT CHOICE FOR TOPO ANALYSES

(Formerly Topo Analyst)

Is your LiDAR and elevation data accurate?

Verify accuracy and quality automatically with CompassTA.

CompassTA™ automatically tests and verifies the accuracy of elevation data products. CompassTA™ lets you test LiDAR point cloud data, DEM data products, and other raster elevation data. With CompassTA™, you can make sure you are creating, buying, or using elevation data that meet your specifications and mapping needs. Start with CompassTA™ and add the LiDAR Testing Extension to provide a complete solution for LiDAR elevation data verification and quality control.

BENEFITS:

  • Flexible Elevation Data Testing: Verify LiDAR point cloud data as well as raster DEMs and elevation data.
  • Differentiate Yourself from the Competition: Cost effectively verify that all elevation data meet specifications and produce the standardized reports to prove it.
  • Compliance: Load checkpoints with land cover type information to report accuracy per client requirements.
  • Automatic Results: Load reference X, Y, and Z data. Elevations from products are automatically extracted.
  • Standards-Based Reporting: Automatically document vegetated (VVA) and non vegetated (NVA) accuracies.
  • Scalable: Input tile layers and evaluate enormous LAS, DEM, Intensity, and Ortho data sets.
  • Extensible: Add the LiDAR Testing Extension to conduct exhaustive LiDAR testing and verification.
  • Adaptable: Use default settings for testing or adjust parameters based on project-specific requirements.

CompassTA™ enables elevation data producers, customers, and users to verify the accuracy and quality of the data by offering the following benefits:

Flexible Elevation Data Testing

Verify LiDAR point cloud data as well as raster DEMs and elevation data.

Differentiate Yourself from the Competition

Cost effectively verify that all elevation datum meet specs and produce the standardized reports to prove it.

Compliance

Load checkpoints with land cover type information to report accuracy per client requirements.

Automatic Results

Load reference X, Y, and Z data. Elevations from products are automatically extracted.

Standards-Based Reporting

Automatically document Fundamental Vertical Accuracy (FVA), SVAs, and CVA.

Fast Answers

Within minutes produce conclusive results. Do my products meet spec?

Scalable

Input tile layers then interact with and evaluate enormous LAS, DEM, Intensity, and Ortho data sets.

Extensible

Add the LiDAR Testing Extension to conduct exhaustive LiDAR testing and verification.

Adaptable

Use default settings for testing or adjust parameters based on project-specific requirements.

Shared Analytics

Accuracy and QC results are easily understood by producers, customers, and users.

Simple, fast, and complete workflow solution to verify the accuracy and quality of orthophotos.

CompassTA™ elevation accuracy software has received OCIO-ITS certification from the U.S. Department of Agriculture (USDA).

Certification allows 40,000 USDA users the opportunity to utilize CompassTA™ software for elevation accuracy verification of LiDAR point clouds, digital elevation models (DEM), and other raster data sets.
