Abstract
This study developed a method of satellite imagery-based land-cover/land-use mapping for Indonesia at 1:50,000 scale, but with a very detailed level of categorization. The method was developed by taking into account: (a) categorization target specified in the reference classification scheme, (b) the ecological characteristics of the Indonesian region, (c) the type of data used, and (d) the main approach that can be applied to all regions in Indonesia. A landscape ecological approach was selected, by combining digital and visual interpretation. The main data source was Landsat-8 OLI recorded in various dates of recording between 2016 and 2018, supported with SPOT-7 and Sentinel 2A imagery. Digital analysis includes geometric and radiometric corrections, pan-sharpening, and vegetation index transformation. Visual interpretation was carried out with an interpretive overlays strategy and/or land unit approach. Field work was carried out for collecting information on terrain characteristics that are relevant to the land-cover/land-use variation, to be used as a basis for re-interpretation process. Based on the developed methods, a set of land-cover/land-use maps on a scale of 1: 50,000 of the southern part of Sumatera, except Lampung Province, was delivered. It covers 247 map sheets. The interpretation accuracies have been assessed statistically, and they reached 79.54% for Bengkulu, 80.75% for Jambi, 79.2% for Riau Islands, and 81.02% for Bangka-Belitung. With a large number of classes has been mapped, i.e. over 70 categories, the accuracy levels achieved in this study were considerably high. Some notes on the results of the mapping were also included in this report.
