Minimum Cumulative Resistance surface and connectivity analysis

On-class stuff

 The theory of resistance is to identify the core habitat as the source or starting point, and then other suitable habitats as the destination, and by assigning differ ent resistance to the surface between the two places, which depends on the land use, slope, and many other factors, and finally derive various evaluation metrics, such as the least-cost pathway or the least-cost road network, or the importance of corridors visualized by currents, and so on. One of the first things I did was to construct a resistance surface, which takes into account factors such as elevation, slope, land use, vegetation FVI/NDVI (with a slight overlap with land use), data on human settlements, and data on road distances, the first four being the more common ones, and with reference to the literature I weighted and analyzed several of them.
