Harp Piemonte — Topographic — 1:50,000 smoke

Topographic base for the representation of geo-environmental themes in raster format on the 1:50,000 scale. The cartography was produced by Arpa Piemonte (Geographical Information System) in the period 2005-2010, with the aim of creating a topographic base on a regional scale useful for the representation and production of geothematic cartography of the Agency and in particular the sheets of the Geological Charter of Italy at scala1:50.000 of the CARG Programme. The final dataset realised in raster format was produced by Arpa Piemonte through a process of elaboration, integration, dressing of numerous vector levels extracted both from the CTR of the Piedmont Region (scales 1:10,000 and 1:50,000) and from other themes of the Agency’s Geographic Information System. The raster dataset is organised in 68 geo-referenced images corresponding to the cutting of the sheets of the official cartography scale 1:50,000.The cartography in the basic version consists of several levels of information (hydrography, roadworthiness, built, altimetry, toponyomas) with background of the altimetric relief to ‘smoke’ produced by virtual shading of the digital model of the ground.本数据集为1:50000比例尺栅格格式的地理环境主题制图专用地形基底。该制图成果由皮埃蒙特大区环境与土地保护局（Arpa Piemonte）的地理信息系统部门于2005至2010年间完成，旨在构建区域尺度地形基底，用于该局地理主题制图的制作与展示，尤其是CARG计划下1:50000比例尺的意大利地质图标准图幅。最终栅格格式数据集由Arpa Piemonte通过处理、整合与整饰多类矢量图层制作而成，这些矢量图层既提取自皮埃蒙特大区1:10000及1:50000比例尺区域地形图（CTR），也来源于该局地理信息系统的其他主题图层。该栅格数据集包含68幅地理参考影像，对应1:50000比例尺官方制图的标准图幅裁切范围。基础版制图包含多类信息图层（水系、道路要素、建成区、高程数据、地名注记），并辅以通过地面数字模型虚拟晕渲生成的晕渲式高程背景。
