Evaluation map color codes on Geodesignhub

Geodesignhub uses a set of graphics conventions and in this article we will articulate the conventions so that it is easy to understand.

All evaluation maps can be shown in a simple three or give color map: Red , yellow and green, or red, yellow, green, green2, green3. The following described these colors:

  • 1 (red) is where the system is “existing” already and in a healthy state, meaning that it is feasible to remain….a constraint in terms of information but not a total Constraint.

  • 2 (yellow) is lowest priority for change… “not appropriate” or not capable of supporting the system, meaning don’t put it there, e.g too wet or steep or….unless you provide change to the basic area conditions e.g fill in the ocean for new land, regrade the mountain, etc… (all very risky projects). This is also a constraint in terms of information.

  • 3 (green) is low but higher priority ….”capable”, meaning that you can place it here IF you also provide the technology and market to make it feasible, e.g. water and sewers, access roads for mechanical harvesting, etc., and the market comes…

  • 4 (green2) is higher priority….”suitable”, meaning that the area is capable of supporting the project and it already has the appropriate technologies to support the activity taking place e.g. septic tank soil or sewers, access roads for mechanical harvesting, etc. BUT there may not yet be a market for the change.

  • 5 (green3) is the highest priority for change….“feasible”, meaning that it is suitable AND there is a demand or market to provide the new land use change, e.g that someone wants to buy the product or new house (and at a profit) OR that the government wants to protect and improve an historical landscape .

In addition, every system has its own colors. All diagrams under that system are color coded. That way, in a synthesis, you can identify colors used for a diagram in a system.
