Abstract

Local climate zone (LCZ) classification is used worldwide to study city's form and function, but its applicability is less explored in the Indian context. The study explores WUDAPT's applicability in medium-sized Indian cities on flat terrain by using LANDSAT 8 Imagery and Google Earth Pro for mapping training areas. The study uses WUDAPT framework to generate local climate zone maps of 15 medium-sized Indian cities with 75 % overall accuracy. The studied Indian cities show low rise development, dominated by LCZ 3, 6, 9. Study also identifies six subclasses. The predominant classes and subclasses share 70 % of the total built area and display high accuracy of 75 % and 66 % respectively, ensuring usability of generated maps. Indian cities show LCZ 3 in core, LCZ 6 in planned layouts and institutional zone and LCZ 9 in city periphery. Studied cities display presence of subclasses displaying transformation within city. Study shows presence of LCZ 3₇ instead of typical LCZ 7 in large population size cities due to government initiatives for urban poor and surge in informal economy. The study explores urban structure and development pattern in medium-sized Indian cities. The developed repository enables all stakeholders to make informed decision for sustainable urban growth.

基于WUDAPT的印度平坦地形中等城市LCZ制图：评价与应用

局部气候带（Local climate zone， LCZ）分类法是世界范围内研究城市形态和功能的常用方法，但其在印度的适用性研究较少。该研究通过使用LANDSAT 8图像和谷歌Earth Pro对训练区域进行测绘，探索了WUDAPT在印度中等城市平坦地形上的适用性。该研究使用WUDAPT框架生成了印度15个中型城市的当地气候带地图，总体精度为75%。所研究的印度城市为低层发展，以LCZ 3、6、9为主。研究还确定了六个子类。主类和子类占总建筑面积的70%，显示精度分别达到75%和66%，保证了生成地图的可用性。印度城市的核心为lcz3，规划布局和机构区为lcz6，城市外围为lcz9。所研究的城市显示子类的存在，显示城市内部的变化。研究表明，由于政府针对城市贫困人口的举措和非正规经济的激增，在人口规模较大的城市中出现了LCZ 37而不是典型的LCZ 7。本研究探讨了印度中等城市的城市结构和发展模式。开发的资源库使所有利益攸关方能够为可持续城市增长做出明智的决策。
