GreenTwins information model on individual plants and plant cover types

This document describes the GreenTwins information model for individual plants and green area plant covers in city models. The GreenTwins information model is built upon CityGML 2.0, and works as a draft for later creating a proposal for a CityGML standard extension (ADE) with respect to SolitaryVegetationObject and PlantCover object types. The document classifies the database layer/object types needed for maintaining the information needed for the GreenTwins algorithmic plant library, and details the parameters stored for each object type in its implementations.
