Hi
I have a big map where there is 1 small polygon shaped like a donut and another smaller polygon shaped like the inner circle of the dodonut. They are 2 distinct polygons but I would like to merge just these 2 polygons of the map.
May I know how can I go about doing it?
The 2 distinct polygons are sharing the same field called polyid which is causing a lot of duplicates in my work.
Which function can i use to merge the 2 polygons?
Thanks
Grace
