Listing of landsat images used for exposure and vulnerability assessment in Kyrgyzstan Compiled for the World Bank Project "Measuring Seismic Risk in Kyrgyz Republic Entries are: gid unique id of the segments label_clas classification of the segments. currently defined labels are: "comm_industrial" (commercial, industrial) "res_highrise" (residential, high-rise buildings) "res_lowrise_highdens" (residential, low-rise buildings, high spatial density) "res_lowrise_lowdens" (residential, low-rise buildings, low spatial density) NOTE: low-rise refers to 1-5 storeys buildings. high-rise refers to 5-18 storeys buildings. High-density refers usually to urban environments, while low-density refers to rural areas. The dataset has been obtained by automatic processing of Landsat 8 (OLI) imagery. The labelling process has been carried out using machine learning techniques, and is based on a training / testing dataset manually labeled by an operator. As result of an automatic procedure, and since is based on medium resolution multi-spectral data, there is no warranty on the accuracy of the dataset over individual features (segments) and small areas.
