the attached java classes together with the patch enables mkgmap to create contour lines directly from digital elevation model (DEM) data. This may be useful for those who don't want to ceate contour lines with other tools and store them in huge(!) files.
It introduces the following new options: --contours If set, create contours. --dem-type Valid values are CGIAR (CGIAR geotiff), ASTER (ASTER geotiff) or SRTM (.hgt files). Default is CGIAR. --dem-path Path to the DEM data files. The default is type-dependant. --dem-increment Verical distance between the contour lines (default is 10m).
Sounds interesting. Does it also distinguish minor and major elevation lines? What determines the area in which the contour lines are calculated? Is there a way to avoid an overload with contours e.g. when processing the whole of Germany inclduing very flat country as well as the the alps? bye Nop
