Here’s basically what I would like to do

Outline a geographic area say a city for instance, and then persist this data
Take a set of geopoints (lat,long) and ‘query’ or search or calculate whatever and determine which location(s) the points are in.

Is this even possible and if yes how? Thanks alot for your contributions guys

p.s. I am working in c# so any code snippets or libraries along those lines will be appreciated

Since you need to persist then look at SQL. It has a spatial types and queries.

In .NET have this but it is 4.5 and new to me.

The terms to search on are spatial and geography
