#3705: i.segment produces empty output
-------------------------------------+-------------------------
Reporter: martinl | Owner: grass-dev@…
Type: defect | Status: new
Priority: normal | Milestone:
Component: Imagery | Version: unspecified
Keywords: i.segment, empty output | CPU: Unspecified
Platform: Unspecified |
-------------------------------------+-------------------------
From G74:i.segment manual:
i.group group=ortho_group input=ortho_2001_t792_1m@PERMANENT
g.region -p raster=ortho_2001_t792_1m n=220446 s=220075 e=639151 w=638592
i.segment group=ortho_group output=ortho_segs_l1 threshold=0.02
The last command says
i.segment complete. Number of segments created: 119346
But output raster map is empty:
r.info -r ortho_segs_l1
min=NULL
max=NULL
All GRASS versions (7.7, 7.6, 7.4) seems to be affected.
