winGrass 7 r.to.vect bug

Hanan Karam

Hi everyone,

 

I’m having trouble with r.to.vect in WinGrass 7 (SVN nightly winGRASS 7 experimental build downloaded on February 23 2013).  For type=’line’ on thinned raster maps of streams produced using r.watershed, it runs to completion but the output data is meaningless.  The command I used, and the output follows:

 

 

GRASS 7.0.svn> r.to.vect -v input=STREAMmap output=STREAMmap_vect type='line'

Extracting lines...

100%

100%

Building topology for vector map

<STREAMmap_vect@HNK2>...

Registering primitives...

11835 primitives registered

66275 vertices registered

Building areas...

100%

0 areas built

0 isles built

Attaching islands...

Attaching centroids...

100%

Number of nodes: 7298

Number of primitives: 11835

Number of points: 0

Number of lines: 11835

Number of boundaries: 0

Number of centroids: 0

Number of areas: 0

Number of isles: 0

Updating attributes...

r.to.vect complete.

 

GRASS 7.0.svn>

 

GRASS_INFO_ERROR(6052,1): Unable to describe table <STREAMmap_vect>

GRASS_INFO_END(6052,1)

 

GRASS_INFO_WARNING(6336,1): Coor file of vector map <STREAMmap_vect@HNK2> is larger than it should be (1261613 bytes excess)

GRASS_INFO_END(6336,1)

 

Any information on this problem would be appreciated. 

 

Thank you,

Hanan
