GMapTool: The Complete Beginner’s Guide to Mapping with Ease

GMapTool is a Windows utility for working with Garmin-format maps (IMG/TYP/UNL). Key points:

• Purpose: split, merge and analyze Garmin map files, create mapsets, extract subfiles, repair or remove unlock codes, and preview maps.
• Formats: primarily Garmin IMG, TYP and UNL; can handle directories of maps and produce compatible mapsets for Garmin devices.
• Main features: batch processing, map splitting/merging, map metadata display, map analyzer/logs, preview compilation, and simple map conversion/management.
• Typical users: Garmin device owners, GPS hobbyists, cartography enthusiasts who compile custom Garmin maps (often from OpenStreetMap data).
• Availability: freeware (Windows), small/lightweight GUI; latest stable builds widely distributed (site: gmaptool.eu) and listed on download sites (Softpedia, LO4D).
• Notes: actively used in the OSM→Garmin map community for building region or country map compilations; always download from the official site to avoid altered builds.
