Diagrams are the basis of Geodesignhub. You can think of a diagram as a simple idea that can be easily understood and communicated. The closest analogy is a explaining something to someone using a back of a napkin, you are going to use rough sketches, some text etc. In Geodesignhub ideas are communicated using diagrams.
Diagrams are design ideas or policies that are created by users and others in a project. Diagrams have three things:
- A representation on a map (e.g. line or polygon on a map)
- A short text describing what the diagram communicates.
- Other meta data attributes such as a cost, timeline, funding type etc.
There are primarily two types of diagrams: Projects and Policies. Projects are ideas that involve construction, building something, moving something and are necessarily linked to a location. For e.g. building a new shopping mall is a project. The second type of diagram is a policy. Policies are things that are not necessarily spatial i.e. linked to a specific location. For e.g. a water management training or education program is not linked to a specific house but to all of the area. A policy could be a rule, regulation that can be introduced as a part of the design strategy. E.g. to promote opening of new businesses, a tax break could be implemented for new businesses. These type of economic tools are examples of policies that can be pursued. A effective geo-management and strategy consists of both projects and policies. The policies are depicted as hatched patterns and projects as solid pattern in Geodesign and a example is below.
