The SpatialAnalysis object exposes some special spatial functions built into iLand. The typical use-case is to extract some gridded data and save them to disk.

Methods

saveRumpleGrid(string filename)
Calculate the Rumple-Index for the landscape with a spatial resolution of 10m (i.e., the cells of the iLand height grid) and extract a 100m grid (average over the 10m cells). Store the grid to filename.

saveCrownCoverGrid(string filename)
generate a map of crown covers (2m resolution), and save an average (100m) to filename. For each tree, the tree crown (as defined by the 'reader' stamp, which defines for 2m pixels the share of that pixels that is covered by a tree crown with a given tree crown radius) is additively plotted on a 2m grid. If that sum is larger then 0.5 (i.e. 50%), a pixel is consiedered as 'covered'. The resulting grid gives for each 100m a fraction of 'covered' pixels.

Properties

rumpleIndex
The rumpleIndex property (read-only) is the value of the Rumple index for the whole landscape.
