    Proximity Search

    We need to display Map of locations within a give area. We do not want to upload the data but rather do a search on the local data by longitude/latitude

    I checked the following microsoft article for that

    Implementing a Proximity Search with SQL Server 2000

    The third paramter to the stored procedure dbo.sp_FindNearby is SearchDistance but what should be the value of the last parameter @EarthRadius to call this stored procedure.

    Re: Proximity Search

    Hi,

    The average radius of earth is 6366 km (just measured it hihi). If your geoUnits are in miles you have to give it in miles I suppose.
