While I find SD to be an incredibly powerful tool both for planning and in flight, I do really miss contour lines. While the various maps and terrain colouring currently available can give you a general idea of what the terrain is like, nothing beats contour lines when at a glance trying to identify terrain on the map by looking out the window.
This is particularly true, I find, for areas with a lot of high terrain such as Scotland, Snowdonia, and even the Peaks (though I wouldn't call the peaks "high"). Ridges, peaks and cols, and other easily identifiable features usually are also quite easy to distinguish on a map with contour lines. Even a fairly small hill in a flat area is quite easy to identify out the window and on a map with contour lines, but much harder (I find) in the current available chart types in SD, unless you happen to accidentally have the high terrain colouring set to the height where it will become identifiable (or fly at that height when in the air and the feature is on).
Any chance something like a 100ft, 200ft, or 250ft increment contour line could be implemented?
Thanks
