Simulation of Smoke Emission from Fires in High-Rise Buildings Using the 3D Model Generated from 2-Dimensional Cadastral Data
Having a 3-Dimensional model of high-rise buildings can be used in disaster management such as fire cases to reduce casualties. The fundamental dilemma in 3D building modeling is the unavailability of suitable data sources. However, available cadastral 2D maps could be used as low-cost and attainable resources for 3D building modeling. Smoke will be a great threat to people's health during a f...
متن کاملFrom 3d geomodelling systems towards 3d geoscience information systems: Data model, query functionality, and data management
Two-dimensional GIS are extensively used in geology to create, analyse, and interpret geological map models. However, these systems are unable to represent the Earth’s subsurface in three spatial dimensions. The objective of this article is to overcome this deficiency and to provide a general framework for a 3d GIS. The presented approach is based on existing 3d geomodelling theory and software...
متن کاملA Parametric Deformable Model to T Unstructured 3d Data a Parametric Deformable Model to T Unstructured 3d Data
Recovery of unstructured 3D data with deformable models has been the subject of many studies over the last ten years. In particular, in medical image understanding, deformable models are useful to get a precise representation of anatomical structures. However, general deformable models involve large linear systems to solve when dealing with high resolution 3D images. The advantage of parametric...
متن کاملSemantics of the PROV Data Model
This document presents a model-theoretic semantics for the PROV data model, viewing PROV-DM statements as atomic formulas in the sense of first-order logic, and viewing the constraints and inferences specified in PROV-CONSTRAINTS as a first-order theory. It is shown that valid PROV instances (in the sense of PROV-CONSTRAINTS) correspond to satisfiable theories. This information may be useful to...
متن کاملMappping Digital Image Texture onto 3d Model from Lidar Data
In this paper, an experiment system is developed to settle the problem about how to mapping a digital image onto 3D model from LIDAR data. Firstly, it chooses the corresponding points between point cloud and digital image, then, uses these corresponding points to calculate the exterior and interior orientation elements and systematic error corrections of image. For the purpose of improving the ...
