Abstract

Selecting a suitable site for urban development in a city is one of the critical issues in urban planning. This study illustrates the use of geographic information system (GIS) and multi-criteria evaluation (MCE) techniques for the selection of suitable sites for urban development in Tiruchirappalli, Tamil Nadu, India. Toposheet and CARTOSAT 1 satellite data were used to generate various thematic layers using ArcGIS software. Using these tools, several suitability factors including slope, soil, geology, road proximity, land use/land cover, depth to water table, distance from built-up area, geomorphology, and water quality map were evaluated. An analytical hierarchical process was used to rank the various suitability factors and the resulting weights were used to construct the suitability map layers. In doing so, the derived weights were used. Finally, a synthesised land suitability map was generated by combining these maps. The results of our research have been submitted to the regional authorities and wi...

地理空间技术在土地适宜性分析中的应用

在城市中选择合适的城市发展场地是城市规划的关键问题之一。本研究说明了使用地理信息系统(GIS)和多标准评价(MCE)技术来选择适合印度泰米尔纳德邦蒂鲁奇拉帕利城市发展的地点。利用Toposheet和CARTOSAT 1卫星数据，利用ArcGIS软件生成各种主题层。利用这些工具，评估了几个适宜性因素，包括坡度、土壤、地质、道路邻近程度、土地利用/土地覆盖、到地下水位的深度、到建成区的距离、地貌和水质图。采用层次分析法对各适宜性因子进行排序，并利用得到的权重构建适宜性图层。在这样做时，使用了派生的权重。最后，结合这些地图生成综合土地适宜性图。我们的研究结果已提交给地区当局和……
