As two instances of GTP model, G\|GTP is used for the real\|3D modeling of subsurface geological bodies, and E\|GTP is used for the real\|3D modeling of subsurface engineering excavations.In the light of the discussions on the features and functions of E 2 GIS, the modeling principles of G\|GTP and E\|GTP are introduced. The two models couple together seamlessly to form an integral model for subsurface spatial objects including both geological bodies and excavations. An object\|oriented integral real\|3D data model and integral spatial topological relations are discussed.展开更多

The concept of habitat, in fact, implies issues of dialectic spaces, in other words, those settings that can be defined as relational subsystems within the urban/domestic scale. This essay has its roots in the CIAM （Congr^s International d＇Architecture Moderne （in English： International Congress of Modem Architecture）） of 1953, during which the complementarity of the outside space next to the dwelling and its relevance within the project discipline, have been affirmed. In particular, assimilating the lesson of Aldo van Eyck, this work investigates the deepest issues of the concept of threshold. The analysis makes use of the work-tools of critical reading and comparison between urban and rural habitats, with different density levels, whose relational fabrics have been layering over time permeable ＂thicknesses＂ which articulate complex threshold spatial configurations.展开更多
