What I am finding is every map except Google Maps shows the GPS captured co-ordinates out by up to 50 metres.
I need the Satellite view, not streets.
Google Maps is spot on (taking into account the 1-2 metre accuracy of the GPS unit I am using) except that Google Maps might display once out of 1000 times I use it (cant seem to get cache to work, different story). The fixes to allow the use of Google
Maps in these discussions (rather than getting the tile error) do NOT work.
Anyway, Bing Satellite Maps is the closest to Goole Maps as some areas I use the tracks on, are remote and not covered by Yahoo Maps. ArcGis do, but the zoom level is not sufficient. But, using Bing compared to Google, the GPS points are about 20 metres
right to what they show under Google Maps.
Is this a failure of GMap, or is it more the Map provider.
What would be perfect is to be able to use Google Satellite Maps all the time (anymore ideas on this).
Is there anyway of tell GMap to compensate? I could change the GPS lat/long, but as they are coming from the GPS device, then I know they are the correct coordinates.
PS Here is an example. -34.262713, 150.942521 is a point on a dirt road, in the middle of an intersection (Under Google). However, it is 10 metres right (under Bing). I need the accuracy of Google though.
