Urban indices

This study aims to propose a concrete process of developing a KPIs system in urban planning by the logic model, and applying it for the case of the Hanoi master plan. In more detail, the logic model will be utilized to understand the plan’s components and their linkages, and then select KPIs based on the model’s outputs and outcomes, and based on Hanoi urban data availability and quality.

The trophic levels in urban lakes are typically based on the forms of nutrition and phytoplankton communities in the lakes. In this study, comparisons between eutrophication indices and the water quality index (VN-WQI) were used to classify the water quality of 20 lakes in Hanoi, Vietnam.

Impervious surface is an artificial surface that prevents water from seeping into the ground. Impervious surface is not only an indicator of the level of urbanization but also a key indicator of the quality of the urban environment. This article presents the results of an impervious surface classification in Ho Chi Minh City area from multi-temporal Landsat image data.

The study results show inter-relationships and transformations of the three indicators in the research context, where urban land temperature and Urban Heat Island (UHI) are raised by built-up areas and in contrast, reduced by vegetated areas. As a result, urban green space would be a driver to mitigate the harmful impact of the "heat island" effect in urban areas. Aim to strengthen concentrated green areas and vegetation in land areas that are less favorable for construction.

This paper presents the method of combining of Sentinel 2 MSI and Landsat 8 multi-resolution satellite image data for urban bare land classification based on NDBaI index. Two images of Sentinel 2 and Landsat 8 acquired closely together, were used to calculate the NDBaI index, in which sortware infrared band (band 11) of Sentinel 2 MSI image and thermal infrared band (band 10) of Landsat 8 image were used to improve the spatial resolution of NDBaI index.
