I have a vector layer of 108374 lines I want to split the vector layer into field names of the layer, which is 17. Now, I want to create a new vector layer containing one of the field names e.g. "OBJECTTYPE". From this field name I want to calculate the distance from a certain category to another vector layer.
I have tried to use "split vector layer" in QGIS, but it gives an error: "TypeError: the sip.simplewrapper type cannot be instantiated or sub-classed".
I'm using QGIS 1.8 Lisboa for Mac.
Thanks in advance.
