contour lines: summit points, depression points and saddle points

hgleixner

Hello, if I generate contours, there is the option "Generate Spot Elevations at MIN/MAX Elevations". That option generates only two additional points. I would like to suggest an option, by which all of the tree kinds of distinguished points of a relief representation would be generated (summit points, depression points and saddle points). It should be possible. Are there chances to get it? Regards Henry

Hi Henry,

Thank you for your suggestion, I have submitted a Global Mapper enhancement request to add Summit, Depression and Saddle points to the 'Generate Spot Elevations at' command. The work order # is 13011.

Regards,

Jasmine

Jasmine,
do you proceed in your plans? Or: can I put the number 13011 into a priority list by myself?

I would highly appreciate if all summits, depression points and all saddles would be generated by one mouse click. For example all summit hights of a topographic map could be checked using a DEM behind the map...

Regards
Henry

On a similar theme, are there any plans to have closed contours around depressions formatted with inward-pointing hatches/hachure marks automatically? I'm not sure if they're used on US maps, but they are in both UK and Canadian topographic maps.
