| Abstract |
This study aimed to explore capabilities of Thaichote (formerly known as THEOS) satellite imagery for land use/land cover extraction in urban and suburban area. Land use/land cover map of Khon Kaen metropolitan and suburban areas was extracted from Thaichote satellite image using geographic object-based image analysis (GEOBIA) techniques. Normalized difference vegetation index (NDVI), Normalized difference water index (NDWI), Built-up area index (BAI) and Principal
component analysis (PCA) were derived from tmospheric corrected reflectance data of the Thaichote's four spectral bands, and were used as inputs for GEOBIA in addition to the standard Red, Green, Blue, and Near-infrared bands. Hierarchical image segmentation was performed to split the multi-spectral satellite image into homogenous regions and objects. Expert rule set based on the objects' color, shape, texture, and contextural were developed to classify land use/land cover of
objects within the city's metropolitan and suburban areas with the help of SEaTH (Separability and
Threshold) tool. The classified land use/land cover objects included road, residential area, gated housing complex, commercial area, bare soil, water body (clear and turbid) and vegetation area (dense and sparse). The land use/land cover map provided a quick and accurate geographic information around Khon Kaen city, which can be used effectively in change analysis for urban and
regional planning. |
