Roadway¶
This node, for the entirety of a sub-area, sets the land cover fractions to a balance of road, concrete, grass and irrigated grass, and then generates trees along the perimeter of the utilised boundary (for a representation of the make-up of a streetscape). It overwrites any data embedded within the land cover grid that the sub-area intersects with (any grid cells only partially overlapped by the node region have their land cover ratios proportionally reduced by the intersection faction). The sum of all entered fractions has to be equal to 1. Tree, water and roof cover will not be assigned to the grid cells at the interior of the sub-area, and tree cover will only appear along the limits of the node region where a tree is contained within a grid cell (see the ‘street tree’ node documentation for more information).
