#2658: v.to.db compactness gives wrong results in feet location
-----------------------------------------------+----------------------------
Reporter: annakrat | Owner: grass-dev@…
Type: defect | Status: new
Priority: major | Milestone: 7.0.1
Component: LibGIS | Version:
svn-releasebranch70
Keywords: v.to.db, units, area, compactness | Platform: All
Cpu: Unspecified |
-----------------------------------------------+----------------------------
I was looking in the source code of v.to.db to understand if computed area
is in meters squared or location units (feet in my case). I realized area
is converted to meters squared, however, perimeter seems to be in map
units (feet). Therefore compactness is wrong when units are not meters
(latlon is fine I guess). Setting feet as units doesn't influence
compactness computation.
Currently the library functions for computing area and perimeter don't
behave consistently.
