A technical note for those who are interested in vector tile creation from PostgreSQL/PostGIS database using nodejs and tippecanoe. This is complicated, but we can flexibly create vector tile with our method. Just an example. #UNOpenGIS #UNVT #vectortile

ズームレベル15までの画像タイル（png）だと、Sentinel-2の1シーン（約100km四方）が約700MB。mbutilでmbtilesにしてもサイズがほとんど変わらなかったのですが、PMTilesでどうなるか私も将来試したいです。（このツイートを見たので、Sentinelのタイル化メモを作成）

I learn #NASADEM has less void areas compared with SRTM. It is based on SRTM, and uses #ASTER GDEM, ALOS #AW3D30 DEM and etc. for void filling. It's a really good source of RGB elevation tile! #LPDAAC #UNOpenGIS #UNVectorTileToolkit #MapLibre #DEM #FOSS4G
