Question about the boston-seaport map #907

Closed sutong-st closed 1 year ago

sutong-st commented 1 year ago

Hi, I want to align the openstreepmap to nuscenes map,so i convert the osm data from WGS84 coordinate system to epsg:3857. The origins are given by the map api. From the vis results, all of the singapore maps are matched while the boston-seaport are failed. I noticed that it seems like the map seems to be scaling (not sure). I use the same pyproj function to convert all maps, am i missing something? Here is my function: Transformer.from_crs("epsg:4326", "epsg:3857", always_xy=True) the osm vis boston-seaport_crossing_ SD_MAP_3

the nuscnes vis drivable_area_MAP_1 It seems like the right part are matching worsely.
