crossing line problem with geojson while using Equidistant Cylindrical (eqc) projection #182

Open hunter3789 opened 2 years ago

hunter3789 commented 2 years ago

I am having a problem with drawing geojson while using Equidistant Cylindrical (eqc) projection. "+proj=eqc +lat_0=0 +lat_ts=0 +lon_0=126 +x_0=0 +y_0=0 +ellps=WGS84 +units=m +no_defs"

When I draw world maps, there are unexpected lines acrossing left and right side of map.

This is the example of eqc projection case and source code. example https://github.com/hunter3789/geojson/blob/main/leaflet_imgoverlay_world.html

Is there any ideas to deal with it? Thank you.

hunter3789 commented 2 years ago

I split the polygons into 2 pieces, which make the acrossing lines. I don't know this is the proper way to deal with, but it looks not bad.

those are the result and source code. example2 https://github.com/hunter3789/geojson/blob/main/leaflet_imgoverlay_world_modified.html

If there is better way, please share me. Thank you.
