System.Data.Spatial DbGeography.Distance units?
Several articles seem to agree on meters being used in 4326 as the unit of distance. WGS 84 is done in meters as well, which is probably why this uses meters. http://blogs.msdn.com/b/adonet/archive/2011/06/30/walkthrough-spatial-june-ctp.aspx http://www.jasonfollas.com/blog/archive/2011/07/20/entity-framework-spatial-first-look.aspx http://blog.simplecode.eu/post/DistancesWithDbGeographyAndDbGeometry
Real time GPS Tracker on JUST HTML / JS and Google Maps to be run on a handphone? Is it possible?

Most browsers in the latest smartphones have implemented the W3C Geolocation API: The Geolocation API defines a high-level interface to location information associated only with the device hosting the implementation, such as latitude and longitude. The API itself is agnostic of the underlying location information sources. Common sources of location information … Read more

I’m not sure if it deals with the fact that the lat/long GPS system is not an x/y coordinate plane. … Read more
