What is the best generic method to check whether an opened table is geographic or not using PyQgis ?

  • I'm not sure I follow the question...are you referring to the data and geographic coordinates? or are you referring to whether the table has an associated spatial element e.g. dbf in a shapefile? – spk578 Jun 23 '15 at 10:43
  • @spk578 Not sure to follow yours either ... lol ... i would answer : the second part of your question (whether the table has an associated spatial element ...) – snaileater Jun 23 '15 at 10:55

You can use the hasGeometryType() method from QgsVectorLayer.

To examinate whether the selected layer has an associated geometry you can run this code in the QGIS Python console:

iface.activeLayer().hasGeometryType()

If it is True, the layer has a geometry (i.e., it's an spatial table). If it is False, the layer is a table (i.e., the table is non explicitly spatial).

    Yes ... in fact at first glance i thought that was not a very "generic" solution since it is only a method from QgsVectorLayer ... but then i noticed that when u open (for example) a .csv file it is considered as a QgsVectorLayer ... so this solution is working for me so far ... – snaileater Jun 26 '15 at 13:33
