Specify here the width of a layer plot (square). The smaller the plot, the higher the accuracy but the heavier in memory. As several layers can be used and mixed inside an elevation terrain, it can be a good idea to create a low level area with big plots and several smaller layers with small size plots for better accuracy, on area of interest.

 

According to the size of the terrain and the resolution specified above, this is the number of plots that will be created.

 

According to the number of plots computed above, this is the memory needed by the layer.
