One more question for you.
I know that the background maps like openstreetmaps/bing/google are typically in spherical mercator. The problem I’m currently running into is that I’m trying to plot a whole bunch of data as points on the map, and all our data is in WGS84.
I know I can reproject the data points so they match the background layer projection, but that’s taking a significant amount of time.
As an example, we are at times having to plot upwards of 20,000 data points. As you can imagine, converting all this data to a different projection takes quite a while.
is there a way to reproject the background layers to WGS84 (4326), so that we can quickly plot our data?
As an added note for this application I believe I’ll be using bing maps for the background.
Thanks for any help.
