Welcome Azhar!
You background and occupations makes you a very important person for this team! You can get us good official information! Will collaborate on that later!
AS for Sub localities, not all neighbourhoods are part of a bigger locality...hence such areas are mapped as Sub-locality/neighbourhood. These neighbourhoods might be part of a n old bigger locality like..say...Gawalmandi...it can have many small mohallas or colonies which are to be mapped as sub locality.neighbourhood. But again, not all sub localities have a parent locality, they are independent locations within the city. So dont worry if some sub localities dont have a Locality parent.
As for multan road. the issue you are facing is due to the fact that many areas have overlapping or closeby boundaires and when you EDIT multan road, the system cant clearly resolve what locality/sub locality to place that part of the road in. The best way to fix this is
1. either delete the road and then redraw.
2. modify the locality boundaires.
I prefer delete and redraw. I am waiting for new imagery for the entire multan road and then we can redraw the entire road and make it split.
BTW, i was on Multan road the other day and there are many small mohallas and neighbourhoods and colonies on the west bank of the road. I was unable to make a list or find a location. Would you be able to get info on all those neighbourhoods and then draw their polygons on the map...this way entire west bank of Multan road will be populated.
We will bug you for more official info...stay tuned!
