I get a periodic email from the NASA Earth Observatory (http://earthobservatory.nasa.gov) with links to interesting images of the Earth. The most recent included a nice image of Ireland’s topography, generated by the Shuttle Radar Topography Mission in 2000.
Fantastic!!! ‘’
I have been reading a lot of the history of “the isles” and these should help. The borders of kingdoms appear to be arbitrary lines until they are overlaid on a topo map.
Have you come across anything similar for the big island? There didn’t seem to be anything like it on the NASA site.
There’s another site (drawing a blank) with satellite images you can use to zoom in. I can find my house and lots of details. I’ll try to remember the name.
Those are great pictures.
Martin, US state lines are easy. For example, if you are in western Nebraska the landscape is kind of flat and scrubby. When you cross into Colorado the landscape is kind of flat and scrubby. See?
Some of it is just clouds, but there is a good bit of snow on the higher mountains. (I used to work in multispectral satellite image processing, writing algorithms for detecting clouds.)
