ETRS89, WGS84 compatibility in Bing Map RRS feed

  • Question

  • Hi All,

    Are ETRS89 and WGS84 compatible in Bing Map.

    I have to convert coordinates in EPSG27700 format to ETRS89 format (via OSTN02) , and use the resulting data in ETRS89 to plot onto Bing Map. What accuracy can I get? Is there a better way? Any links or information?

    difference between WGS84 and ETRS89

  • The answer is the same as to your last question: http://social.msdn.microsoft.com/Forums/en-US/vemapcontroldev/thread/e2f9b32c-3042-4258-9069-8b6d7c2320b7

    Namely, the Bing Maps API expects all latitude/longitude coordinates to be defined using WGS84. Web mapping providers such as Bing Maps are not designed for high-accuracy geodesy and surveying applications, and if the difference between ETRS89 and WGS84 really matters to you, then Bing Maps is probably not the right tool for you to plot that data :) If you're happy with accuracy +/- approx one metre, then it's probably safe for you to treat ETRS89 and WGS84 as being equal.
