Hi Mike, - I also wondered if mkgmap should produce more DEM levels when --dem-dists is missing, the problem is that I was unsure about the values to use. - I like your suggested option names but I'd prefer not to change the options this late to avoid confusion. - There is only one overview-dem-dist because MapSource and Basecamp don't need more and the overview map is not used on the GPS. - Can you explain what effect you expect when you use --dem-poly with the areas.poly from splitter? My understanding is that this should not change the map, at least not visibly, as the areas.poly simply describes the outline of the rectangular tiles. On the other hand it makes sense to use the poly file that was used as input for splitter.

The explanation says "mkgmap tries to determine a reasonable value based on the resolution found in the *.hgt files", but it also says "for gps devices you need one for each resolution given with the --levels option". It seems to me the default behaviour should be to produce a map suitable for GPS devices, and hence it should determine a set of values. I suggest renaming this option --dem-distances as its meaning is clearer. Also I suggest capitalising GPS. I suggest renaming --overview-dem-dist to --dem-overview-distance so that all the DEM options begin with --dem. I also suggest moving the explanation to immediately after --dem-dists. As --overview-levels allows multiple values, does the DEM overview level also allow multiple levels (in which case the name needs to be --dem-overview-distances)? If not, we need a mention why only a single value is needed. For the --dem-poly option, I suggest adding a mention that the areas.poly file produced by splitter can be used.
