#975: WxGUI should provide area measurement tool --------------------------+------------------------------------------------- Reporter: marisn | Owner: [email protected] Type: enhancement | Status: new Priority: normal | Milestone: 6.4.0 Component: wxGUI | Version: unspecified Resolution: | Keywords: d.measure Platform: All | Cpu: All --------------------------+------------------------------------------------- Changes (by hamish):
* keywords: => d.measure * platform: Unspecified => All * component: default => wxGUI * cpu: Unspecified => All Comment: see d.measure which does this for xmons; G_area_of_polygon() is used (lib/gis/area.c). Importantly it works for lat/lon too. classic case for SWIG style links to libgis, but a new m.area module could take a series of coords and spit out an answer. does the wxGUI measurement tool use geodetic distance for lat/lon locations?
