Global Mapper User's Manual
The Contour Options panel (displayed above) allows the user to set the contour interval and units as well as
the grid spacing to use when generating the contours. You can also restrict the elevation range within which
contour lines are generated (by default all loaded elevation values are considered). In addition, options are
available to generate isoheight area features in addition to contour lines as well as spot elevations at the
highest and lowest points in the area over which the contours are generated. The smoothing option controls
whether or not extra vertices are added along generated line and area features to improve their appearance. If
you need to generate a huge amount of contour lines over a large area, the option to export the contours
directly to a package file can be used in addition to the Gridding tab options to export those contours directly
to package files to get around memory limitations. Note that the contour lines will be generated so that the
higher elevations are to the left of the contour line.
The Simplification panel (displayed below) allows the user to set up the threshold at which points that don't
contribute much to the shape of the generated contour are removed in order to generate lines with less
vertices. The Gridding panel allows you to break up your contour generation into smaller pieces which can
sometimes help reduce memory requirements when generating a very large amount of contour lines. The
Export Bounds panel allows the user to set up the portion of the loaded elevation grid data they wish to
consider when generating the contours.
