Re: [Qgis-user] different buffer for the same field

I solved both cases of the previous email. If you want to buffer starting from a specified distance stored in a field, please have a look on this post [0] (written by me): [0] https://howtoinqgis.wordpress.com/2016/11/28/how-to-buffer-v ectors-from-fields-in-qgis-using-python/ If you want to

Re: [Qgis-user] different buffer for the same field

Don't worry for the delay... Your goal is to generate the buffer a priori (i.e. by assigning a specific value of radius for each feature, without any preliminary edit on the layer) or by searching for it in a field of the layer (i.e. as Randal Hale suggested)? Marco 2016-11-27 18:54 GMT+01:00

Re: [Qgis-user] different buffer for the same field

Dear Marco, apologies to write you only now. Yes with variable distance buffer is fine. Thanks a lot. If you can, could you please write me the PyQgis script for the other option? all regards, Azzurra 2016-11-16 9:22 GMT+01:00 Marco Grisolia : > If you want to assign

Re: [Qgis-user] different buffer for the same field

In the processing Toolbox there is a tool called Variable Distance Buffer. If you add a field to your data giving each type a width (field called bufferwidth and it is 10, 20, 30 , 40 meters for each type) - you can use that tool to automatically buffer each fault accordingly. Good Luck!

Re: [Qgis-user] different buffer for the same field

If you want to assign a specified buffer for each kind of feature, you may use a simple PyQGIS script using a call of buffer() from QgsGeometry(). Are you able to do it? Otherwise I may try to write it for you if my understanding of the problem was right. Therefore, if your buffer distances are

[Qgis-user] different buffer for the same field

Dear all, I have a shape file with a field called “type”. In the “type” field I have 4 kinds of samples ( 19 records). See in the attachment. The 4 samples are: normal fault, inverse fault, overthrust, syncline. I would like to create a buffer with different distance for each sample (the
