How to make a Grid Overlay of residences

For some use-cases, it may be useful to have a Grid Overlay of locations of residences. Residences may sometimes be treated with additional care or consideration, or may have additional restrictions or protections applied to them. As such, having a dynamically calculated overview of their locations can be very relevant. Such a Grid Overlay can be created by testing which locations have a defined size for residences.

Editor → Current Situation (Ribbon tab) → Overlays (Ribbon bar)

How to create a Grid Overlay of residences:

1. 

   Add an Average Overlay, configured so that:
   Name: Social residences
   Attribute to average is SOCIAL_UNIT_SIZE_M2
   Averaging distance is 0

2. 

   Add an Average Overlay, configured so that:
   Name: Market residences
   Attribute to average is NORMAL_UNIT_SIZE_M2
   Averaging distance is 0

3. 

   Add an Average Overlay, configured so that:
   Name: Luxury residences
   Attribute to average is LUXE_UNIT_SIZE_M2
   Averaging distance is 0

4. 

   Add an Combo Overlay, configured so that:
   Name: Residences
   A: "Social residences" Overlay
   B: "Market residences" Overlay
   C: "Luxury residences" Overlay
   Formula: GT(ADD(A,B,C),0)
5. Switch to the "Legend" tab, and activate the "custom legend".
6. Remove all pre-existing entries.

7. 

   Add an entry, configured so that:
   Name: Not residences
   value: 0
   Color: black
8. Add an entry, configured so that:
   Name: Residences
   value: 1
   Color: lightgray

Notes

• Although there are also "senior housing" and "student housing" categories of residences available, those are rarely used and as such not includes in the instructions. To add them, add 2 more Average Overlays with SENIOR_UNIT_SIZE_M2 and STUDENT_UNIT_SIZE_M2 respectively, add then to inputs D and E of the Combo Overlay, and expand the formula to include the D and E parameters: GT(ADD(A,B,C,D,E),0)
