Updating CHCNAV map data helps keep your surveying projects, GIS layers, and field mapping information accurate. CHCNAV GNSS systems generally use LandStar surveying and mapping software for map visualization, project data, GIS files, and online basemaps rather than traditional road navigation maps. LandStar supports vector data, raster data, CAD files, and online map sources such as Google, Bing, WMS, and WFS layers.

This guide explains how to download and update CHCNAV map data step by step.
