How to make a Grid Overlay of residences
Revision as of 11:17, 6 July 2023 by Rudolf@tygron.nl (talk | contribs)
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.
How to create a Grid Overlay of residences:
- Add an Average Overlay.
- Set the averaging distance to 0.
- Set the target Attribute to "SOCIAL_UNIT_SIZE_M2".
- Duplicate the Average Overlay, and in the duplicate change "SOCIAL_UNIT_SIZE_M2" to "NORMAL_UNIT_SIZE_M2".
- Duplicate the Average Overlay again, and in the duplicate change "SOCIAL_UNIT_SIZE_M2" to "LUXE_UNIT_SIZE_M2".
- Add a Combo Overlay.
- For inputs A, B, and C, set the Average Overlays created earlier.
- For the formula, enter the following:
GT(ADD(A,B,C),0). - Switch to the "Legend" tab, and activate the "custom legend".
- Remove all but 2 of the pre-existing entries.
- Change one entry to a black color, and a value of 0. Change the name of the entry to "Not residential".
- Change the other entry to a lightgray color, and a value of 1. Change the name of the entry to "residential".
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)
