In addition to providing the key large scale datasets from Ordnance Survey GB and LPS (formerly Ordnance Survey) NI, we offer what we believe to be the broadest range of detailed suppliers for both aerial imagery and height data.
Imagery is available from the 1940s to present day at resolutions of up to 4cm.
Height (surface and terrain) data is available in grids of up to 25cm spacing and +/- 10cm accuracy. Such high detail datasets can result in significant file sizes which is where Global Mapper has proved to be an invaluable tool to many of our customers - even those with previous significant investment in 3D software tools.
Some of the most recent additions to the service include an online oblique imagery viewing and measuring tool for cities across Europe and also the provision of pre-built 3D city models.
