Hi
I currently use multimap for many of my locations for my databases, as it gives both grid references and Lat/Long's as well as most arial views.
The conversion from grid ref. to Lat/Long is fairly Accurate.
I have come across various internet mapping sites like :
Easymap, Getamap, Getmapping, Google Earth, Mapquest, Streetmap, Yahoo Maps.
Are there any others that you would recommend, that give either excellent ariel views, or grid references or Lat / Long's especially with high definition or large scale.
Regards
