I have some Geodataframe points they are positions of millions points in the world.
I need a “rastermap” on the world map. Another point is that as the number of points are huge, I don’t want to face crash in loading points. and I don’t want to lose the quality and want to update dynamically when zoom in.
I need a picture similar to this:
I am not so professional. I tried this code to rasterize the points implicitly:
but when I run. The output don’t show the map properly and shows this:
what would be your suggestion for me?
I’d need some more information, which coordinate system is your data in for example? I’d also recommend trying datashade=True instead of rasterize=True.
In fact I have a geopandas.GeoDataFrame that their geometry is points wit Longitude and latitude and their crs is:
points_gdf.crs = {‘init’ :‘epsg:4326’}
I tried to use
rasterize=True . the map is :
the problem is with colouring here. It is blue. how can I change the colours for that?
rasterizing makes it yellow-red. I prefer that.
the result for that is:
I know that the problem with rasterizing is that the black part is rendered and it makes a black layer in front of the map :
therefore I tried to make them transparent:
but the result shows only white raster on map:
Another problem is that if the number of positions are huge, when I want to use :
pn.serve(plan1)
I see an error " waiting for localhost"
that nothing show up.
