Detailed Description

This class contains a set of Plant Instances. It is implemented as a subclass of vtFeatureSetPoint2D, a set of 2D locations of the plant stems. It can be read from/written to the VF format ("vegetation file") designed specifically for the purpose of storing plants, which makes it very compact and much more efficient than, e.g. SHP format.

Member Function Documentation

uint vtPlantInstanceArray::InstancesOfSpecies ( short  species_id)

Given a species index, return the number of instances which are of that species.
