Hi, if there’s a image over map, we need to draw coastline to make it easier to read.
I have tried this:
import geoviews as gv
import geoviews.feature as gf
gv.tile_sources.OSM() * gf.coastline.opts(projection=ccrs.GOOGLE_MERCATOR)
The result is wrong although the coastline has been reprojected.
What if you just do
import geoviews as gv
import cartopy.crs as ccrs
gv.extension("bokeh")
gv.Points(([-88], [40])).opts(projection=ccrs.GOOGLE_MERCATOR, global_extent=True) * gv.feature.coastline() * gv.tile_sources.OSM()
Another way:
import xarray as xr
import hvplot.xarray
ds = xr.tutorial.open_dataset("air_temperature")
ds.hvplot("lon", "lat", coastline=True, projection="GOOGLE_MERCATOR")
Ha, interesting. Projected points * coastline * tile works. Don’t know the logic behind it, hah. Anyway, thanks for the solution.
I think this works too if you zoom out / set .opts(global_extent=True)
