How to create a polygon from a list of X,Y values

[JoseSanchez]

Hi all

I have a table that has X.Y coordinates that represent project areas on the field.

The structure is:

Project Number, X,Y
1, X1,Y1
1, X2,Y2
1, X3,Y3
1, X4,Y4
2, X11,Y11
.....



Questions:
- How can I create a polygon in Python from that list
- how can I loop, to read all the points that belong to the same project
- how can I loop to read all the projects

Regards

The simple way would be to use the create features from text file.

Otherwise you can recreate that functionality using array polygon constructions. The code sample at the bottom should get you going in the right direction.
