![]() The link between a delimited forest ( boundary= forest) and its compartments is spatial, as for all boundary entities: a compartment is considered part of a delimited forest if and only if its boundary= forest_compartment entity is spatially fully encompassed by the boundary= forest entity. Note that a delimited forest is not always divided into compartments. Consequently, boundary= forest_compartment relations should never overlap. There must be a 1:1 correspondence, that is to say one boundary= forest_compartment entity by compartment, and one compartment by boundary= forest_compartment entity. 1.1 What if I encounter a natural= wood/ landuse= forest (multi)polygon which in fact represents a forest compartment?.These markers are useful navigation aids. These units are marked on the ground by boundary markers (painted marks, signs attached to trees, posts or boundary stones) showing a unique identifier ( ref) for the compartment. ![]() Each compartment should be modeled as a single boundary= forest_compartment entity, without consideration for any land lot boundaries which may encompass or be contained within the compartment. Though boundaries of forests and their compartments on one hand, and land lots on the other hand, frequently overlap, a given delimited forest or forest compartment may be composed of multiple land lots, and a single land lot may be divided in multiple delimited forests or forest compartments. Forest compartments are not a land lot nor a cadastral parcel. A forest compartment is a single piece of a given delimited forest, which is identified by a reference, often a number, which is unique inside the delimited forest.
