I know of Google Maps, Streetmaps and a few others, but there never seems to be the facility to input an OS grid Reference and then view the area in anything other than an actual standard map display. I want to do aerial recces of sites without buying and flying my own light aircraft or helicopter and the only way I've found to do it is to put the GR into one of the sites that uses them (Streetmap, Get A Map, etc) and then cross referencing them with one of the Google Earth type systems! Time consuming and slightly annoying!
Anyone know of a good site that will allow me to input OS GR (and not Lat/Long!) and be able to get a satellite image of the position?
