Zoomable maps (512x512px)

I created these maps of Cornwall using a sliding scale of transparent to green to show elevation, and a sliding scale of transparent to red to show slope. This version of the scale overlays the green in on a white base, from 0-250m elevation above sea level, with an additional light yellow overlaid from 100-350m. The red ramps in from 0-15 degrees (33%) slope.
