LBA-ECO LC-24 CADASTRAL PROPERTY MAP OF URUARA, PARA, BRAZIL: ca.1975

This data set contains a shapefile of a digitized map of the land parcel information of the original properties of the Uruara colonization site, Para, Brazil, acquired from the Instituto de Colonizacao e Reforma Agraria, or the Colonization and Agrarian Reform Institute (INCRA). The Uruara settlement geometry was initially designed by INCRA, and consists of mostly 100 hectare lots (400 x 2500 meters, and 500 x 2000 meters), running north and south of the Trans-Amazon Highway, as a fine network of small, narrow rectangles. The other parcels in the landscape are the so-called glebas that range up to 3,000 hectares.

The map was in the form of a paper map without a projection (a spherical geographic coordinate system) in the South American 1969 datum (SAD 1969). This paper map was digitized in Environmental Science Research Institute (ESRI) ArcInfo 8.1 using a digitizing table, and the digital cadastral data were geo-referenced and projected to match the Universal Transverse Mercator projection (Zone 22 South, World Geodetic System 1984 datum) of Landsat imagery (Landsat.org). There is one compressed (*.zip) file with this data set.

本数据集包含巴西帕拉州乌鲁阿拉殖民定居点原有地块地籍信息数字化地图的形状文件（shapefile），数据源自巴西殖民与土地改革研究所（Instituto de Colonizacao e Reforma Agraria, INCRA）。乌鲁阿拉定居点的空间布局最初由INCRA规划设计，地块以100公顷规格为主，包含400×2500米与500×2000米两种尺寸，沿跨亚马逊公路南北两侧分布，形成细密的小型狭长矩形地块网络。区域内其余地块为所谓的glebas（地块单元），最大面积可达3000公顷。
该原始地图为无投影纸质地图，采用1969年南美大地基准面（SAD 1969）下的球面地理坐标系。此纸质地图通过数字化桌，在环境科学研究所（Environmental Science Research Institute, ESRI）ArcInfo 8.1软件中完成数字化作业，随后对数字地籍数据进行地理配准与投影转换，使其匹配Landsat影像所采用的通用横轴墨卡托投影（Universal Transverse Mercator）南22区、1984年世界大地测量系统（World Geodetic System 1984, WGS84）基准面，相关影像信息可查阅Landsat.org。本数据集附带1个压缩格式（*.zip）文件。
