I wish to dynamically generate a Google Maps overlay, that will consist of a single transparent GIF/PNG image with multiple dots on various locations.
There will be a large quantity of dots and if I use normal markers, the performance will be unacceptable.
I came across the SharpMap library and it looks like an excellent, comprehensive library for dealing with maps.
Problem is, it's also very big and I'm not sure where to begin.
For starters I don't think I need to use the whole framework, and I may not even need to instantiate a 'Map' object.
All I need to do is convert a collection of latitude/longitude co-ordinates into a collection of pixel co-ordinates, given the current zoom level and the size of the viewport (which is fixed).
Can anyone who's had experience with SharpMap point me in the direction of what classes/namespaces I could/should be using to get this done?
Found an article somewhat related to this, but applied to Google Earth rather than the Maps API.
Trying to get the sample working.
