Hi all, sorry, seems I forget what I already found before: there is probably no way to avoid interpolation, so I think it is better to remove the option from splitter again.

Hi all, with current code in mkgmap this option is of no use, as mkgmap rounds the dem-dist values (down) to multiples of 16. (9942 -> 9936 , 3314 ->3312) This means that points are always interpolated, no matter where the tile boundaries are. So, I see two possibilites: 1) remove the option from splitter (it is not yet documented anyway) 2) change the code in mkgmap to allow using the exact dem-dist values without rounding I think this works fine with MapSource and Basecamp, but maybe some devices will not be able to handle that, as Garmin maps always use the rounded values. A possible benefit of the exact values is that we may be able to avoid interpolation, at least in some areas of the world. What do you think?
