Abstract

This paper presents a study on extracting information: Normalised Difference Vegetation Index - NDVI (Normalised Difference Vegetation Index), Urban Index - NDBI (Normalised Difference Built-up Index), Zero Surface Difference Index Homogeneous - NHFD (Non-Homogenous Feature Difference) from multi-temporal Landsat satellite images and GIS established a map of urban spatial distribution at the time of 2010, 2015 and 2020 in Phu Ly city, Ha Nam province. Research results show that multi-time remote sensing data contribute to monitoring and evaluating the process of urban spatial expansion quite accurately, in line with the reality and regional development planning of Phu Ly City. Specifically, the expansion of urban space from 2010 - 2015 and the development of the core zone from 2015 to 2020. The city's urbanisation rate in the past 10 years is also high - about 40%.
