#3846: r.contour started producing broken/segmented contour lines since 7.4
-----------------------+-------------------------
Reporter: metello | Owner: grass-dev@…
Type: defect | Status: new
Priority: normal | Milestone:
Component: Raster | Version: unspecified
Keywords: r.contour | CPU: x86-64
Platform: MSWindows |
-----------------------+-------------------------
Since GRASS 7.4, some contour lines generated by r.contour are broken into
several segments (until 7.2 was ok). I have a system that uses r.contour
to trace reservoirs for hydroelectric plants and that problem is breaking
my algorithm.
In the attached GRASS project, you can see the result generated by
different GRASS versions (contour level = 229) - look at the largest
contour line. I tested the following versions: 7.2.3, 7.4.4, 7.6 and
7.7svn. Only 7.2.3 produced a continuous/unbroken contour.
