WebJun 30, 2024 · To obtain the desired level of spatial compactness for each scenario, the Boundary Length Modifier (BLM) was calibrated to generate a reasonable trade-off between boundary length and cost (Stewart and Possingham 2005), using Zonae Cogito software (Watts et al. 2009). BLM values between 5 and 8 were used. WebTo address this issue, we can further modify the problem by adding penalties that punish overly fragmented solutions (via add_boundary_penalties () ). Here we will use a penalty factor (i.e., boundary length modifier) of 0.003, and an edge factor of 50% so that planning units that occur on the outer edge of the study area are not overly penalized.
