amazonULC Data Package

The Amazon-ULC Data Package, available as an R package, provides Urban Land Cover (ULC) classifications for selected cities in the Brazilian Amazon. The study areas cover approximately 1,200 km², including the municipal seats of Altamira (153 km²), Cametá (44 km²), Marabá (164 km²), Santarém (143 km²), and part of the Metropolitan Area of Belém (614 km²), all located in the state of Pará.These land cover maps have significant value in urban planning for Amazonian cities, as they can aid in monitoring urban sprawl, restricting construction in environmental protection areas, assisting in urban zoning, and identifying high-density areas, among other uses. Our classification model used images from the WPM sensor of the CBERS-4A satellite, and combined the GEOBIA approach, data mining techniques, and the random machine learning algorithm.亚马逊城市土地覆盖（Urban Land Cover, ULC）数据集包以R语言包形式发布，可为巴西亚马逊地区的选定城市提供城市土地覆盖分类结果。本次研究的区域总面积约1200平方千米，涵盖阿尔塔米拉（153平方千米）、卡梅塔（44平方千米）、马拉巴（164平方千米）、圣塔伦（143平方千米）的市政辖区，以及贝伦都会区的部分区域（614平方千米），上述区域均位于巴西帕拉州境内。该土地覆盖制图成果对亚马逊地区城市的规划具有重要应用价值，可辅助监测城市扩张、限制在环境保护区域内开展建设活动、协助进行城市分区规划以及识别高密度城区等诸多场景。本次研究所用的分类模型以中巴地球资源卫星04A星（CBERS-4A）的WPM传感器影像为数据源，融合了面向对象影像分析（Geographic Object-Based Image Analysis, GEOBIA）技术、数据挖掘方法与随机机器学习算法。
