google maps api 3 - .NET Geolocation Library -


i have set of few hundred uk locations specified post code. need find within n miles of given uk location. have google maps api can translate postcodes long/lat coords. know database platforms have various geospatial capabilities (mssqlspatial, postgis etc) avoid platform specific app db agnostic (thanks fluentnhibernate).

is there open source library enable me query dataset spatially in memory? dataset small , locations in uk perhaps use northings , eastings?

for small datasets, not concerned query performance , spatial indexing (i.e. full table scans ok), use haversine formula calculate distances between location , postal codes.
