MetropoGIS: A City Modeling System

The contribution of this paper is threefold. First, we will report on a system that automatically generates a 3D block model from digital aerial images. In this part we will focus on the automatic aerial triangulation and a dense matching process. The second part addresses the augmentation of this 3D block model of a real city with geo-referenced terrestrial data of the facades. The terrestrial...

scour modeling piles of kambuzia industrial city bridge using hec-ras and artificial neural network

today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...

Metropogis: a Feature Based City Modeling System

In this paper we report on a system to extract 3D information from oriented digital facade images using various feature extraction/matching methods. We emphasize on 2D feature extraction from digital images including contour chains, line segments and vanishing points. The extraction of 3D primitives is based on line matching over multiple oriented views and 3D plane detection by a line grouping...
