BUILDING INFORMATION IN ITALY In this section, three main sources of data on buildings are presented: the Topographic Database, the new format for local and regional

The algorithm is divided into two steps in order to acquire good models from a huge hypotheses space and to solve the non-linear problem: the constraint-based reasoning using

1) While IndoorGML has more detailed subdivision, LADM provides larger spatial units but follow the borders of IndoorGML units (this would be considered to

A 3D indoor GIS representation of building structures aimed at emergency response is integrated with the indoor Geometric network Model (GNM) to create the network

Our proposed methodology to define operations on the basis of prismatic polytopes is straightforward: (i) an (n − 1) -dimensional object or set of objects is extruded into a set of

As a result, in the context of this paper, a 3D WebGIS application is developed in order to successfully retrieve and visualize CityGML data in accordance with their

Dynamizers support inlining of O&M data representing sen- sor observation values, which then are injected into the at- tributes of specific city objects.. This approach is useful

Here, we present a multi representation concept (MRC) that enables a user-defined definition of LoDs. Because CityGML is an international standard, official profiles of the MRC
