anthropogenic alterations have affected urban hydrology in india and have generated a wide range of hydrological problems. such alterations include increase in directly-connected impervious cover thus reducing natural groundwater recharge. in the past urban runoff was largely viewed as a nuisance, but within the new paradigm of sustainability, this water is recognized as a potential resource. t...

Uncertainty in spatial data attributes can produce unreliable spatial patterns in choropleth maps, but only a few studies have considered uncertainty in map classification processes. Unfortunately, a less desirable classification result often is generated by existing methods. For example, most observations are assigned to a single class while the remaining classes have a very small number of ob...

Distribution plan for a bottled drinking water company in the Central Asian Region is developed using Quality Function Deployment (QFD). The QFD explores the essential customer expectations as important information to construct an efficient distribution plan to augment responsive water distribution Supply Chain (SC). The significant SC characteristics those are necessary in meeting the customer...

Enterprise systems must have the structure to adapt the change of business environment. When rebuilding enterprise system to meet the extended operational boundaries, the concept of IT city planning is applicable and effective. The aim of this paper is to describe the architectural approach from the integrated information infrastructure (In3) standpoint and to propose for applying the “City Pla...

This paper presents the urban wind ventilation mapping from building frontal area index on the example of urbanised city, Hong Kong. The calculations of frontal area index for each uniform 100m grid cell are based on three dimensional building databases at eight different wind directions. The frontal area index were then correlated with land use classification map, and the results indicate that...

In this paper we describe the construction of a city model and its support for the analysis of image sequences. Our city model consists of building models which were generated from large scale vector maps and laser altimeter data. First the vector map is analysed to group the outlines of buildings and to obtain a hierarchical description of buildings or building complexes. The base area of sing...

It is interesting to observe unique challenges and opportunities faced in developing countries to solve a problem that has been extensively studied for years and acceptably resolved in the developed world. Map-matching is one of such areas of research. Existing well established map-matching algorithms are based on data mostly from the developed world where road networks are planned, GPS coverag...

J. L. Borges once wrote about a Chinese emperor, who commanded the creation of an accurate map of China [1]. The resulting map was as detailed as possible but therefore it had to match the size of China. What use would make such a map, especially if you have a narrow navigation question, e.g. where the forbidden city is located? This legend makes the central problems involved in graphical visua...

We have developed a map-based approach which enables us to efficiently extract object features from aerial images. We match an image with i ts corresponchng map in order to estimate the object states in the image. This approach is characterized by i t s active use of a figure contained in the map a s the object model for comparison. We determine the principal steps for the map-based approach fo...

This paper proposes a method for detecting changes of a scene using a pair of its vehicular, omnidirectional images. Previous approaches to the problem require the use of a 3D scene model and/or pixel-level registration between different time images. They are also computationally costly for estimating city-scale changes. We propose a novel change detection method that uses features of convoluti...
