MARS® Software

The Merrick Advanced Remote Sensing (MARS®) software suite is a comprehensive, production-grade, stand-alone Windows application designed to visualize, manage, process and analyze LiDAR point cloud data.

The MARS® software suite is designed for 64-bit Windows operating systems and provides powerful LiDAR filtering, editing, and data management functions.


QC Module
  • Now provides automated reporting for the USGS NGP Lidar Base Specification Version 1.2, including a very rigorous LAS 1.4 file checker which tests for compliance and file integrity, and provides robust reporting of LAS v1.4 attribute information
LAS version 1.4 handling
  • Improved support for LAS v1.4 data processing
  • Improved WKT CRS data handling for LAS v1.4
  • Improved support for LAS v1.4-bit flag processes and interdependencies
Control / Checkpoint reporting
  • A major overhaul of the control/checkpoint report GUI tool to be in line with ASPRS Positional Accuracy Standards for Digital Geospatial Data and the USGS NGP Lidar Base Specification Version 1.2
  • Robust handling and reporting of both control points and checkpoints with robust statistics for NVA and VVA type points
Application Improvements
  • Significant improvement in stability of on-the-fly TIN generation, refreshing, and display
  • New filter and tool to modify bit flag status for points in user-defined areas
  • Many bug fixes to improve performance and stability


  • MARS® FreeView
    Free viewing application supports basic LiDAR data navigation and 3D visualization – the perfect tool for casual users. No license required!
  • MARS® Explorer Evaluation
    Free 30-day trial version featuring data import/export capabilities and automated data production functions. LAS file size limitation of 300 MB.
