OSMから建物データをエクスポートして、Maplibreで3次元表示

https://k96mz.github.io/20240419building3D/VTbuilding2explodeio.html

詰まった点

  • OSMから普通にエクスポートすると、「other_tags」という属性の中にネストされる形で「height」属性が存在。そのため、QGISの「Explode HStore Field」というツールを使用して、「other_tags」属性の中にある「height」属性を展開。
  • shp→GeoJSONに変換後、そのままベクトルタイルにするとうまく高さが表示されない。geojson.io（https://geojson.io）のサイトに一度インポートして、そのままエクスポートとすると形式が整う？のか、ベクトルタイル変換後にうまく高さが表示される。

@smellman が作っている OSMFJ PMTiles をビューアで見るなら https://protomaps.github.io/PMTiles/?url=https%3A%2F%2Ftile.openstreetmap.jp%2Fstatic%2Fplanet.pmtiles#map=16.23/36.441858/139.814481/149/56 で大丈夫で、show attributes を enable してから見ていただけるとわかるように、render_height が良い感じです。

サイトを紹介いただきありがとうございます。render_heightに建物の高さ情報が入っているのですね。
