Hello,
I am trying to make vector tile base on Mapbox pbf standard.
First, convert data from EPSG4326 to EPSG3857 and export as .json.
Second, use mapbox/tippecanoe to generate vector tile in pbf format
Third, use mapbox/pbf, @mapbox/vector-tile and zlib, and use toGeoJSON
Finally, I got the following results
and in the coordinates:
[ -48.427734375, 74.74118495548183 ]
[ -48.7353515625, 74.78737860165961 ]
[ -48.6474609375, 74.74118495548183 ]
[ -48.4716796875, 74.71803680830911 ]
[ -48.427734375, 74.74118495548183 ]
this coordinate is very strange, the origin data is in EPSG4326 and I convert the data in EPSG3857,
but the above data is obviously not EPSG4326 or EPSG3857.

Does anyone know why this is? Thanks in advance
