Garmin IMGフォーマットについて
IMG is the format of the vector maps Garmin installs on its devices: eTrex, Oregon, GPSMAP, Edge bike computers, automotive Drive units. It is not a picture but a map with a road graph, so the device will plan a route on it, find an address and warn you about turns — with no internet.
The export is for when the stock map is not enough: in your region the manufacturer only provides rivers and highways, and you need hiking trails, recent development or a district that simply is not in the catalog. OpenStreetMap is updated by the community daily, and a map built from it is often more detailed than the factory one.
On export the selected layers are converted into OSM data and compiled by the mkgmap program — the standard Garmin map building tool the whole community uses. The output is a single gmapsupp.img file with routing, a search index and points of interest; labels are written in UTF-8.
If the server-side build is unavailable for some reason, the export will honestly report an error rather than hand you a file the device will not accept.

Garmin IMGのエクスポート方法
エクスポート後の開き方
- The device directly — connect the Garmin over USB and copy the file into the Garmin folder on the unit or on the microSD under the name gmapsupp.img; after a restart, enable the map in the map settings.
- GPSMapEdit — another way to view the .img on a computer: you see the layers, roads and points of interest before writing it to the device.
- QMapShack (free) — opens .img on a computer: a convenient way to check the contents before writing it to the device.
- Be careful with the file name — if the Garmin folder already contains a gmapsupp.img, it will be overwritten: rename the old one (for example to gmapsupp1.img — many models read several) or merge the maps.
