2017 - Detailed Land Use Vector Covers - 2020 Edition

Vector-type georeferenced database containing homogeneous groupings of data referring to the various types of detailed land use 2017, reference scale 1:10.000. The 2017 detailed land use reclassification, carried out in 2019/20, was born from the need to provide detailed characteristics to fully meet the demands in the urban and land use field. The previous versions in fact had a minimum area of 1.56 hectares, while the new editions made with detail features have a minimum area of 0.16 hectares and a minimum size of 7 meters for linear development elements. The detailed land use was achieved through the use of color TeA (RGB) and infrared orthophotos.本数据集为矢量型地理参考数据库，收录了针对2017年各类详细土地利用类型的同质数据分组，参考比例尺为1:10000。2017年详细土地利用分类体系的重分类工作于2019至2020年间开展，其研发初衷是提供精细化属性特征，以充分满足城市与土地利用领域的相关需求。此前的版本最小图斑面积为1.56公顷，而本次采用精细化要素制作的新版数据，最小图斑面积降至0.16公顷，线性地物要素的最小长度阈值为7米。本详细土地利用数据通过彩色RGB（TeA）与红外正射影像制作完成。
