Just installed the contour lines plugin, and downloaded some elevation data. Looks great!

However, the contour lines always seem to be metric; is there a way to switch to imperial units (i.e. feet)?

The contour line are always mertric, as are the OpenStreetMap-sourced maps.

Thanks for confirming! I opened two issue for this, 3348 and 3349.

Since OpenStreetMap does not have contour data, contour lines are generated off of other datasets. Often they are based on the US SRTM Digital Elevation Model (DEM) datasets but there are others datasets available that might have better coverage in some areas, etc. It is up to the person/project creating the contour lines from whatever DEM data they decide to use. Contours can be generated in any measurement system desired, but since many/most of these projects are based in metric countries, the contours are usually metric.

In the case of OsmAnd, where are the contours generated? Does OsmAnd
downloads DEM data, or contour vector data?
