Garmin GPI (Points of Interest)
Price before paymentGarmin GPIは、Garmin製GPS機器向けのPOIデータベースフォーマットです。.gpiコンテナは仕様が非公開で、事実上の正準実装はリバースエンジニアリングされたgpsbabelのライターですが、これはワーカーイメージに同梱されていません。そのため現状では正しい.gpiを生成できず、APIは破損したファイルを返す代わりに/api/renderでHTTP 501を返します。当面はGPXをご利用ください（Garmin BaseCamp / POI Loaderで開けます）。

Garmin GPIフォーマットについて
GPI is the container for custom points of interest on Garmin devices. Lists of cafes, fuel stations, parking or service objects are packed into it, and the navigator shows them on top of the stock map. The format is proprietary and has never been publicly documented.
That closedness is what decides how the file is built. There is only one practical benchmark of correctness — the writer from GPSBabel, recovered by reverse engineering; home-made byte writing diverges from it in the header, the nested records and the terminators, and devices reject such files. So we do not write the container ourselves: the points of your area go out as GPX, and that reference tool turns them into the .gpi.
The file carries the point features of the chosen area with their OpenStreetMap name and category: cafes, shops, pharmacies, fuel, parking, attractions. Lines and outlines are not stored — .gpi is a points format, not a map.
Names survive the trip. There is no Unicode inside a .gpi: strings are written in a single-byte code page, and a hard-coded choice would silently turn "Аптека" or "Café" into question marks. We pick the code page that fits the content of your area, and fall back to UTF-8 when one page is not enough. And there will be no empty file: if the area holds no points we say so plainly instead of handing you a technically valid .gpi that shows up as an empty list on the device.

Garmin GPIのエクスポート方法
エクスポート後の開き方
- Garmin device — put the .gpi into the Garmin/POI folder on the unit or the memory card; after a restart the points show up in the custom POI section.
- Garmin BaseCamp — opens the .gpi directly: the points are visible on the map, and from there you can send them to a connected device.
- Garmin POI Loader (free, Windows and macOS) — if you want to move the points onto the device together with your own icons and proximity alerts.
- The easiest way to inspect the contents on a computer is to convert it back: gpsbabel -i garmin_gpi -f poi.gpi -o gpx -F poi.gpx gives you the list of points with their names.
- If you need a map with roads and routing rather than a list of points, that is the neighbouring format — Garmin IMG.
