Abstract: The infrastructure development for economy is really imperative towards developing countries. Therefore, this process brings several unexpected impacts. Landcover change caused temperature increase is one of the most noticeable thing in this process. This impact along with global warming bring out significant consequences about the health, the economy and the society. There are many approaches for analysis the link between the landcover change and the temperature change. However, the satellite image processing is considered as a modern, quick and accurate method. For analyzing the effect of urbanisation on temperature variation in Danang City, Vietnam where the urbanized process is taking place in high speed and complicatedly, this study processes the Landsat satellite image over past years. The result shows that the temperature in Da Nang city changes from 28.77°C to 32.24°C over seventeen years (2001 – 2017). The analysis also demonstrates that there is a relation between the urbanisation process and city warming. It might be the crucial basic for planning the urban area more effective and more sustainable, as well for mitigating the negative impact of temperature change due to urbanisation on the public health, economy development. Furthermore, the paper is hoped to present a new approach in applying satellite image for evaluation the impact of urbanisation on temperature change for lack of observed data.
