Hello,
I’ve been experimenting with your USA maps in Oruxmaps; very nice, thank you! Is there a way to display contour-line labels in feet rather than meters? Better yet, have contour interval in round number feet, say 50feet?Thanks!

I’m aware that in USA,GB,aso the units are imperial rather than metric.
Unfortunately contourlines in feet are not possible.
1.) The tool for producing the contour lines works in [meter] only.
2.) There is no real “elevation” data in Vectormaps, the contourlines have to be preprocessed as “ways” like highways/paths and these ways are displayed.So there is no way to display “flexible” elevation lines [imperial/metric]
Sorry

June 26, 2017 at 10:40 #18171mbe57ModeratorChristian picks the SRTM data from different sources and generates those contour lines by a script and adds those “ways” to the map.
