8.3 Processing Tools
The entire process for Local Plans with 7 steps (4 mandatory + 3 optional) is documented at Processing Tools > UPN / Streetnames > General procedure:
Step 1-2 for planning and UPN are explained on this page, street identification (step 3) and house numbers (step 4) etc on the following page (Chapter 8.2.3).
Step 1 is the design and digitization of the Local Plan, with all parcels and their planning zones (in 'style'), no entries into 'ids' or 'display label'. Be sure, that all units are properly 'snapped'. Never digitize any lines, points, streets into any plan (SDF, Structure Plan, Local Plan).

Following functions are available under Processing Tools > UPN / Street names (plus Chapter 8.2.3):
a) UPN Assignment
You can automatically assign UPN to all parcels of a Local Plan. UPN are 'Unique Parcel Numbers' established 2009 in Ghana to identify all parcels in Ghana with a unique number, used by Land Sector Agencies and administration bodies. They consist of the UTM-km grid (bottom left corner) and a sequential number. For example, 781-0620-0004, which is parcel # 4 in the 781000-620000 UTM grid. More details on UPN are explained in Chapters 8.2.2a and 7.7.1.
In the automatic process to assign UPN (strongly recommended) you select the completed Local Plan DRA file: Processing Tools > UPN / Street names > UPN assignment > Select the Local Plan file (it has to be in the SL folder of the District) > Accept 10 sqm as the minimum area for polygons > Execute
Recommended: Assign UPN with this Tool after you have completed digitizing the entire layout.This takes care of additional UPNs (including in the DRA file).
It will detect the new or modified parcels and assign UPN to the GIS file and to the Address Database. The previous will remain the same.
If this is not the case, you better copy the Address Database from the network / master computer to this computer.
Technical Note: If you really want to cancel all previous UPN assignments, you first have to cancel all UPN (in field 'id label') in Map Maker: Live layers > IDs and labels > Amend labels and IDs > OK > Set all display labels to > (empty) > OK
b) UPN List
There are two options for listing UPN. (This is not part of the processing of Local Plans.)
A) The main system to retrieve UPN listings and references is through the Address Database (Chapter 8.3.3)
B) UPN listing specifically for a particular Local Plan can be generated through Printing Tools > Local Plan > Legend / UPN list.
