Hi, In attempting to patch two polygon layers I am confused as to the the results i am getting. My understanding of v.patch is that it would be similar to a `union` operator in SQL (not a spatial union) wherein rows of one or many tables are concatenated to a new table. However, the results i’m getting are not in aligned with that expectation.
Here is a link to an image of the two tables (one orange, one green) ( https://pasteboard.co/GXjWm6P.png ) The second image ( https://pasteboard.co/GXjVSQE.png) is a result of # combine all clustered polygons into one table gsc.parse_command('v.patch', flags = 'e', overwrite = True, verbose= True, input = <green>, <orange>, output = ssPoly) The blue represents the result of the v.patch command. I don't understand why all of the area covered by the two source vectors is not covered in the patched vector. My only thought it it has something to do with the categories, or keys? Thanks in advance for any guidance. Peter
