Thanks Salvatore,i tried:epsg = vlayerA.crs().authid()
epsg = epsg[5:len(epsg)]
self.epsg = int(epsg)
because i'd like to convert the string to integer but i receive this error:
p, li { white-space: pre-wrap; }
self.epsg = int(epsg)
UnboundLocalError: local variable 'int' referenced before assignment
Do you know why?
Thanks
Francesco

Ogg: Re: [Qgis-developer] Extract epgs code from input layer
Hi,
2013/2/16 francescobocca...@libero.it <francescobocca...@libero.it>
Hi all,
i would like to extract epsg code from inputvector layer.
My code is:
vlayerA = QGisLayers.getObjectFromUri(self.getParameterValue(href.INPUT))
self.epsg = vlayerA.crs().srsid()
Is it corrects?
If i print the values it show strange value.
Those are not strange values, the srs id is the primary key that reference to
SRS in sqlite db.
You should use authid() [1] to get EPSG code or description() [2] to get a
textual description of the SRS.
