To evaluate a planning area or to implement plan procedures, planners need database in the form of land use, population density, housing density and point information regarding various facilities. At present planning tasks are carried out by manual methods where analytical capabilities are limited. Therefore, there is a need for reliable data as well as comprehensive database information indicating physical factors and good analytical tools. In a development plan various standards are specified in zoning regulations for the development of a city. To get an overall view, how these standards are implemented on the ground in planning period, a GIS application can be useful in analysing various amenity standards with respect to population and distances. In this study, for part of Bhubaneswar, basic data was generated from 1988 aerial photographs and other related information was gathered through field survey and secondary sources. The derived information in the form of a map has been entered into computer through digitization. Vector information was later converted into a raster form for the analysis. As per the planning standards catchment areas were created for limited facilities/services like schools, parks, play ground and accessibility to bus stop from main road. The population actually served by these facilities were calculated and compared with the existing planning standards. This particular study demonstrates the use of GIS in one of the planning tasks especially analyzing the residential areas as per the set standards such that improvement schemes can be proposed accordingly in the deficient areas. 相似文献

The rapid growth of urban population in India is a cause of concern among country??s urban and town planners for efficient urban planning. The drastic growth of urban areas has resulted in sharp land use and land cover changes. In recent years, the significance of spatial data technologies, especially the application of remotely sensed data and geographical information systems (GIS) has been widely used. The present study investigates the urban growth of Tiruchirapalli city, Tamilnadu using IRS satellite data for the years 1989, 1992, 1995, 1998, 2001, 2004, 2007, and 2010. The eight satellite images are enhanced using convolution spatial enhancement method with Kernel (7?×?7) edge enhance function. Supervised classification method is used to classify the urban land use and land cover. The GIS is used to prepare the different layers belonging to various land uses identified from remotely sensed data. The analysis of the results show the drastic increase of built up area and reduced green cover within the city boundary limit. 相似文献

Urban sprawl development around Aligarh city: A study aided by satellite remote sensing and GIS 总被引：2，自引：0，他引：2
Rapid urbanization causes disorganized and unplanned growth of towns and cities. The pressure of an ever growing population
becomes a burden on the limited civic amenities which are virtually collapsing. Asymmetrical growth of urban centres consumes
agricultural land adjacent to these, resulting in lower agricultural productivity. Besides taxing the groundwater resources
available for an urban centre, an increase in the paved area severely reduces the groundwater recharge potential, leading
to situations which may truly be potential catastrophes. An understanding of the growth dynamics of urban agglomerations is
essential for ecologically feasible developmental planning. With almost a third of India’s population already having become
urban, it is necessary to acquire information on growth patterns of cities and how they impact the living environment. The
current trend of spatial urban growth in almost all Indian cities has a haphazard pattern, particularly along the urban-rural
fringe. There is an obvious need for continuously monitoring the phenomena of growth, and mapping and analyzing its patterns,
since this is of great concern to urban administrators and planners whose concern it is to provide basic amenities and infrastructure
for the complex urban environment.
Mapping urban growth by conventional methods is too tedious and a slow process, and by the time information becomes available
to planners, it is already outdated and redundant since the damage has already been done. Satellite remote sensing data and
application of GIS technologies provide an alter-native means of rapidly assessing the dynamics and development of sprawl
so that timely action may be taken. Besides being flexible and extensible, the datasets are easily rectified, updated and
may be used for other applications. 相似文献

A Computational Method for Estimating the Demand of Retail Stores on a Street Network and its Implementation in GIS 总被引：9，自引：0，他引：9
This paper describes a computational method for estimating the demand of retail stores on a street network using GIS. First, the 'network Huff model' is formulated on a network with the shortest-path distance as an extension of the ordinary Huff model (which assumes a continuous plane with Euclidean distance). Second, using this model, a formula for estimating the demand is derived. This estimation formula is similar to that with the ordinary Huff model, but it has an advantage in that the formula exactly computes the demand on a network. Third, a practical method for computing the formula is developed. Finally, a method of implementing this computational method in a GIS environment is shown. 相似文献

少有学者测度规划道路系统分析出的空间形态与规划师空间形态规划意图的一致性。为更好地落实规划师的空间形态规划意图,以安厚镇为例,提出"基于GIS和空间句法的空间形态一致性测度"方法。主要思路为:首先,基于规划的城镇道路系统用GIS空间分析技术及集成度、智能度等句法变量分析新一轮城镇空间形态,然后,测度分析出空间形态与空间形态规划意图的一致性。测度结果表明经分析出的城镇空间形态与规划师本意的一致性有待改善,主要表现为城镇发展轴整体智能度较低、可理解性不高,城镇空间拓展主轴较大程度偏离原规划拓展方向,城镇发展次轴对空间结构的引导效用高于主轴。 相似文献

Integration of Remote Sensing and GIS to Detect Pockets of Urban Poverty: The Case of Rosario, Argentina 总被引：1，自引：0，他引：1
The advent of high spatial resolution, multispectral satellite imagery has allowed analysis of remotely sensed images of urban land cover to become more useful to urban planning and decision making than in the past. The addition of radar imagery at relatively high spatial resolution (6 metres at best), with the advantages that it is not affected by cloud and diurnal light conditions and that it is sensitive to the target's geometric shape, surface roughness and moisture content offers additional capability in this regard. This paper incorporates analysis of Canadian RADARSAT-1 and American Landsat TM satellite imagery and ground-based GIS data to identify known pockets of urban poverty. Poverty is defined, based on a limited number of census variables related to dwelling construction materials and per household overcrowding. The objective is to provide a proof of concept that remote sensing data, especially from synthetic aperture radar, and ground-based GIS data can be successfully integrated for urban planning purposes. The results suggest that the approach used is reasonable and that, with future refinement, it offers planners and decision makers a timely and cost effective means to locate and monitor poverty pockets in urban areas. This is especially important in large, rapidly urbanising areas in the developing world. 相似文献

When planners intervene in urban systems they seek in part to generate a positive response from those parts of a city outside of their control, namely the private market and private individuals. This response is difficult to predict due to the fact that the city is a nonlinear system of organized complexity. Models of cities which seek to explain this response are necessarily complicated and dynamic. Where an analytical solution is not possible we turn to computer simulation and interactive visualization in order to understand their output. Allowing human participation in such simulations provides a sandbox in which to experiment with the dynamic behaviour of an urban model and play a part in its evolution. Two possible options for structuring this participation are: (1) toy retail systems, which allow unconstrained experimentation, and (2) games, which impose rules and involve role‐play and competition. To explore these ideas we construct a toy retail system and a two‐player retail game, both of which are derived from an existing agent‐based retail model. We explore the application of these systems to the metropolitan county of South Yorkshire in the UK. 相似文献
