Chongqing, as the central city of inland China, has been subject to especially fast economical development. With increasing population and urban development, various impacts on the surrounding environment, such as deforestation, urbanization and pollution, must be taken into consideration. In particular, decrease in vegetated area and disruption of local ecosystems due to urbanization has emerg...

The objective of this work was the presentation of a knowledge-based framework for the identification of urban features, as well as additional land cover types, contained in the image scene. The test area used was located in an urban environment of Aghios Stefanos, Attica. An IKONOS image (spatial resolution of 1m-resampled) was acquired for the study area and further pre-processed. Furthermore...

This study examines the relationship between diurnal temperature range (DTR) and land use/land cover (LULC) in a portion of the Southeast. Temperature data for all synoptically weak days within a 10-yr period are gathered from the National Climatic Data Center for 144 weather stations. Each station is classified as one of the following LULC types: urban, agriculture, evergreen forest, deciduous...

Salcedo Village has become more susceptible to urban heat effects because of its continuous development. This study investigates urban retrofit strategies that effectively mitigates the heat through modelling and simulation in ENVI-met. It is identified to have a maximum of 1-1.4K heat increase over 100% of its area, recorded during December 23:00 at 2m from the ground. The temperature increase...

Urbanisation is a long standing problem and phenomenon all around the world. It means more and more challenges for scientists. Remote sensing techniques with high spectral and spatial resolution open novel approaches which enable the analysis of vegetated and non-vegetated urban surfaces with high heterogeneity. In this paper it is demonstrated how hyperspectral images and thermal maps can be u...

Segmentation of vegetated areas is inevitable in precision agriculture and has high importance in urban area with social and environmental aspects. This paper addresses the segmentation of fused high resolution multispectral satellite images into distinct regions such as vegetation, buildings and barren land. Even though the IHS based fusion of satellite imagery improves the visual interpretati...
