I want to make a hydrological corrected DEM, using v.surf.rst for interpolation/aproximation and v.breach to introduce aditional elevation points at streams.
My spatial reference system is EPSG:3763 ETRS89 / Portugal TM06, (metrical). As required in v.breach document: - each input vect line have a unique category in layer 1; - input lines not cross themselves; - input lines not constitute loops; - the input vector lines not stand out of the input raster DEM; - the input lines direction is from upstream to downstream. After creating a DEM using v.surf.rst I want to correct the false sinks in narrow valleys and sparse points areas. Using v.breach I have as result two output vectors for streams lines and points but without entities or attributes. I tried with both PostgreSQL and Sqlite database connections. For PostgreSQL connection: DBMI-Postgres driver error: Cannot select: SELECT cat,lcat,z,z_breach FROM topografia.vbreachpoints_2 ERROR: column "z" does not exist LINE 1: SELECT cat,lcat,z,z_breach FROM topografia.vbreachpoints_2 ^ Unable to open select cursor: 'SELECT cat,lcat,z,z_breach FROM topografia.vbreachpoints_2' Copy table failed Table <vbreach_2> does not exist in database <host=localhost,dbname=grass_pp_muda_pttm06> The table <vbreach_2> is now part of vector map <vbreach> and may be deleted or overwritten by GRASS modules DBMI-Postgres driver error: Cannot create index: create unique index vbreach_2_cat on vbreach_2 ( cat ) ERROR: relation "vbreach_2" does not exist Cannot create index DBMI-Postgres driver error: Cannot grant on table: grant select on vbreach_2 to public ERROR: relation "vbreach_2" does not exist Cannot grant privileges on table vbreach_2 Select privileges were granted on the table Any ideas? If wanted I'll send the files needed for replication.
