Defining a zoning problem. The following information is adapted from Serra-Sogas et al. 2020 and Grantham et al. 2013. Defining a zoning problem can be broken down into seven steps. These steps are specific to setting up a Marxan with Zones planning framework, and are...

Boundary Length Modifier vs. Zone Boundary Cost.

Boundary Length Modifier vs. Zone Boundary Cost In standard Marxan, the Boundary Length Modifier (BLM) is a parameter used to control the spatial compactness of solutions (compact versus fragmented solutions). Standard Marxan The BLM works the same way in Marxan with...

Zone contribution.

Zone contribution In standard Marxan with Zones, users have the option to define zone contributions (how much each feature contributes towards meeting targets within each zone). If an overall target has been set then it is mandatory that zone contributions are set....

How can costs get allocated to different zones?

How can costs get allocated to different zones? In Marxan with Zones, it is possible to have multiple costs applied to a zone, and it is possible to apply different costs to different zones. The zone-specific multiplier is used to weight and sum costs per zone. It...

Difference maps from selection frequency maps in Marxan with Zones.

Difference maps from selection frequency maps in Marxan with Zones In Marxan with Zones, creating difference maps (maps that show the differences between solutions) can be complicated. These are usually created using the selection frequency maps of different...

Zone specific targets.

Zone specific targets. In Marxan with zones users can set zone specific targets for features in addition to an overall target. This is useful when users want to separate conflicting features (e.g., conservation features and fishing features) into appropriate zones....
