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.

This paper presents the long-term morphological changes of the sand spits at the Ken Inlet in Ha Tinh Province and Phan Inlet in Binh Thuan Province, Vietnam. The analysis results show that the sand spit morphology at Ken Inlet was drastically changed before the completion of the Da Bac sluice gate construction in 1992, after that the sand spit elongation rate became stable at a rate of about 68 meters per year.

Vietnam experiences increasing droughts throughout the dry season due to climate change, global warming, and human-caused activities like urbanization and deforestation. Drought hazard significantly impacts socioeconomic, agriculture, and the environment; it directly threatens human lives, livelihoods, food security, and environmental degradation.

Nghiên cứu đã sử dụng mô hình CA-Markov như một công cụ hỗ trợ để phân tích và dự báo xu hướng thay đổi thảm phủ/sử dụng đất (LULC) trong đó có lớp phủ rừng tại tỉnh Đắk Nông. Đầu tiên nghiên cứu đã so sánh độ chính xác của phương pháp phân loại theo hướng đối tượng OBIA (Object Based Image Analysis) và phân loại dựa vào pixel MLC (Maximum Likelihood Classification) để phân loại ảnh vệ tinh Landsat năm 2017.

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.

In this study, we mapped and evaluated LULC changes in Huong Hoa district, Quang Tri province, over a period of 10 years based on Landsat 8 satellite image data processed on ArcGIS software. On that basis, we carried out the simulation of the LULC change for 2033 using the QGIS MOLUSCE plugin.

Monitoring and evaluation of saline water intrusion is an important task, especially for agricultural production in Ben Tre province. The paper introduces a new solution in the application of Landsat 8 satellite imagery and field survey data to determine the soil electrical conductivity (EC) for soil salinity assessment through the distribution of EC indice value.

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.

In this thesis, I have proposed a LCC method for these areas. Firstly, a dense time-series of composite images was constructed from all available multi-year Landsat 8 images over the study area. A m odified compositing method was proposed for the compositing process using Landsa t 8 SR images.

Remote sensing can be used to support a wide range of applications in Earth’s land surface information management. Typical applications concern, e.g., the mapping of changes due to the effects of pollution and environmental degradation over different periods of time, thanks to the high frequency of coverage of the Earth surface by satellites.
