Hey,
I'm using the Graphab 3.0 version and want to create corridors in my network (based on a 10x10 m raster). For the corridor setting I select the same max distance as for the linkset and in case of the raster calculation i don't choose a specific metric, but a beta-parameter of 1 (as this is also a fixed setting for the vector-calculation). After i calculate both raster and vector with identical settings, both results show the same "expansion" outside of habitat patches. The vector result is presented through polygon boundaries, the raster through the pixel values.
I wonder, what defines the expansion of the polygon and assigned raster values >0? Moving in direct or diagonal lines from one habitat patch to another, finding possible paths, while staying inside the max dist threshold?
The raster has values assigned to each pixel, what is their meaning? I can't find an explanation, how to interpret the values apart from representing a gradient of probability of crossing two patches. (Manual p.21)
Also, why does the corridor raster assigns values to pixels inside the habitats?
I would be happy to hear from you!
Have a nice day
Frederik
