Quality Control (QC) Module

Merrick has updated the MARS® Quality Control (QC) Module to verify compliance of lidar data deliverables to the Lidar Base Specification (Version 1.2) from the U.S. Geological Survey (USGS).

The QC Module is included in the MARS® Explorer QC and MARS® Production license levels. The QC Module supports Merrick's internal data production workflow requirements, as well as our client's QC needs during data acceptance. The output product of the automated QC analysis includes summary and detailed QC reports that our clients can use to efficiently identify and mitigate data quality issues.
