    Convert MapPoint Lat/Long to Local City X/Y

    Hi, All.
    I need to generate a set of X/Y coordinates for a city size area. I have figured out how to generate Lat/Longs using MapPoint 2010 desktop and load these values into a SQL 2005 table. However, the great circle sql code I have found (so far) to compute distances between my lat/longs seems to be prohibitively slow. My old cartesian product code would take about fifteen minutes to refresh my database after I load new addresses. the great circle function is taking over ten hours.
    Is there a way to get MapPoint to give me a set of X/Y coordinates, so that I can use my old cartesian production functions to compute the distances I need?

    Thanks in Advance,

    John

    You can translate to UTM.. there should be some well-known code or library to convert lat/lon to UTM.

    Also, have you considered SQL Server Spatial? I think it is in version 2008+?

    Re: Convert MapPoint Lat/Long to Local City X/Y

    What you need exactly ?
    Is it the lat lon of an address or lat lon of the round of the city ?
    How did you get the adresse from a windows form, website or other ?
    In wich langage do you want to develop ?
