Service Description:

The local connectedness pixel values refer to a relative measure of resistance that different types of land cover offer to the movement of organisms. These values were assigned by biome and the assumption is that the greater the structural difference between a given type of land cover and the original vegetation of the biome, the greater the value of the pixels that make up that specific type of cover. In this raster, the Kernel linear decay function was used to consider the spatial context in which each pixel is inserted in, recognizing that closer pixels have a greater influence on each other than more distant pixels.

Title: Local connectedness
Author: clicia.barata@tnc.org_TNC
Comments:
Subject: The local connectedness layer seeks to translate, comparatively between classes, the degree of difficulty of movement of a given organism (animal or propagule) in different land cover class. This layer is based on the surface resistance layer, adding the context in which each pixel is inserted in. The premise assumed here, for all biomes, is that the greater the structural difference of that class to the original habitat of the biome, the greater the difficulty of moving through a given pixel. The analysis that generated this map recognize, therefore, that a low-resistance pixel surrounded by high-resistance pixels will be a worse dispersal alternative than if that same pixel were surrounded by low-resistance pixels.
