10This driver writes .map files to be used with WAsP. The only allowed
11geometries are linestrings.

23---------------------
24
25-  WASP_FIELDS : a comma separated list of fields. For elevation, the
26   name of the height field. For roughness, the name of the left and
27   right roughness fields resp.
28-  WASP_MERGE : this may be set to "NO". Used only when generating
29   roughness from polygons. All polygon boundaries will be output
30   (including those with the same left and right roughness). This is
31   useful (along with option -skipfailures) for debugging incorrect
32   input geometries.
33-  WASP_GEOM_FIELD : in case input has several geometry columns and the
34   first one (default) is not the right one.
35-  WASP_TOLERANCE : specify a tolerance for line simplification of
36   output (calls geos).
37-  WASP_ADJ_TOLER : points that are less than tolerance apart from
38   previous point on x and on y are omitted.
39-  WASP_POINT_TO_CIRCLE_RADIUS : lines that became points due to
40   simplification are replaces by 8 point circles (octagons).

42Note that if not option is specified, the layer is assumed to be an
43elevation layer where the elevation is the z-components of the
44linestrings' points.
