This January 2025 Trimble product bulletin explains how to enable a dust filter in Trimble MX60 mobile mapping systems using the TMI software. The filter prevents the system from capturing excessive dust in challenging environments like unpaved roads and mines. It works by defining a "filter box area" based on the system's height, ignoring data within that area. Accurate height measurement is crucial to avoid data loss. The bulletin provides instructions for enabling the filter, optimal settings for best results, and troubleshooting tips for visualizing data gaps. Contact information for technical support is also included.
