Mapbox GL JS 的授權改變,以及 MapLibre GL 的誕生

看到「MapLibre GL is a free and open-source fork of mapbox-gl-JS (github.com/maplibre)」這篇,翻了一下資料發現年初時 Mapbox GL JS 的軟體授權從 v2.0.0 開始變成不是 open source license (本來是 BSD license),而社群也馬上 fork 最後一個 open source 版本並且投入開發,變成 MapLibre GL

MapTiler 在年初的時候有提到這件事情:「MapLibre: Mapbox GL open-source fork」。

The community reacted swiftly: forks of the latest open-source version were made almost immediately by multiple parties. In another positive development, the community came together the next day and agreed to make this a joint effort, rather than splitting energies. A video call was organized and the MapLibre coalition was formed. It includes people working for MapTiler, Elastic, StadiaMaps, Microsoft, Ceres Imaging, WhereGroup, Jawg, Stamen Design, etc.

MapLibre GL 目前與本來 v1.13.0 相容,可以直接抽換過去 (後來在二月的時候有出一個 v1.13.1,不過那是在 v2.0.0 改 license 之後的事情了):

  "dependencies": {
-    "mapbox-gl": "^1.13.0"
+    "maplibre-gl": ">=1.14.0"
  }

記錄一下,以後要在網站上用的話,得注意到 Mapbox GL JS 在沒有註冊的情況下不能使用,而且 SDK 會強制蒐集資料:

Mapbox gl-js version 2.0 or higher (“Mapbox Web SDK”) must be used according to the Mapbox Terms of Service. This license allows developers with a current active Mapbox account to use and modify the Mapbox Web SDK. Developers may modify the Mapbox Web SDK code so long as the modifications do not change or interfere with marked portions of the code related to billing, accounting, and anonymized data collection. The Mapbox Web SDK only sends anonymized usage data, which Mapbox uses for fixing bugs and errors, accounting, and generating aggregated anonymized statistics. This license terminates automatically if a user no longer has an active Mapbox account.

不過如果是抓 OpenStreetMap 資料的話,Leaflet 應該還是目前的首選...
