pulkovo / stereo 80 to mercator conversion

Hey everyone I wanted to overlay layer of vector tiles build in Stereo 80 (Pulkovo) over the arcgis map

Because i cannot do it on the fly i was trying to convert it using a few cli tools ... my code looks as follows

```

ogr2ogr -f GeoJSON -s_srs EPSG:3844 -t_srs EPSG:4326 reprojected.geojson geojson_tiles/*.geojson

tippecanoe -o ancpi_webmercator.mbtiles -Z10 -z16 reprojected.geojson --force

mb-util --scheme=xyz --image_format=pbf ancpi_webmercator.mbtiles tiles_webmercator/

```

the tiles get generated but they are a bit shifted

arcgis is trying to load a certain set of tiles and i have a different ones generated

for ex .... i have this => tiles/12/2264/1530.pbf

the map is looking for => tiles/12/2325/1471.pbf

do u have any idea what i am doing wrong in the conversion process?

thanks,

Rares
