[mkgmap-dev] DEM: performance with bicubic interpolation

Wed Jan 24 13:57:57 GMT 2018

Hi Gerd,

maybe someone will add more input to this discussion, but for me now 
following solution make sens: provide option dem-interplation with 3 values:
- bilinear - fast interpolation for all layers,
- bicubic - precise interpolation for all layers,
- auto - default settings - automatically switching between bilinear and 
bicubic, depending on DEM and HGT resolution.
