MOLISEDB.GIS.MO_degrade_poi_5

The feature class MO_degrado_poi_5 represents the degradation of the territory — punctual elements acquired from the map of elevations and land degradation on a scale of 1:25 000. The maps PTPAAV (Territorial Environmental Country Plan of Area Vasta) are a series of thematic maps drawn up since 1989 and finished and approved at the end of November 1991, are divided into territorial areas for a total of 8 areas identified on the regional territory. The work was carried out by several groups of technicians, a coordination group which established by circulars the standards to be used for the drafting of plans ranging from the thickness of the graph tip to the type of retino and the nuances to be used, and 8 design groups one for each area, which have created the maps trying to standardise spatial information as much as possible. The paperwork of this work was delivered to us in 2008 by the Environmental Heritage Office of the Molise Region. The latter already had scans of some thematic cards related to some areas, the missing ones and in the case of scans not found suitable for georeference, have been scanned. The mapping basis used by the working groups for the creation of PTPAAV maps was the IGM on a scale of 1:25,000.要素类MO_degrado_poi_5指代地表退化状况——其为从1:25000比例尺的高程与土地退化地图中提取的点状要素。 地图PTPAAV（Territorial Environmental Country Plan of Area Vasta）为一系列专题地图，自1989年启动编制，最终于1991年11月底完成并获批。该系列地图按行政片区划分为8个分区，覆盖莫利塞大区全域范围。 本次制图项目由多组技术人员协同完成：其中协调小组通过通告明确了制图需遵循的统一标准，涵盖图笔尖粗细、网纹（retino）类型与所用色调等细节；另设8个片区设计小组，各负责对应片区的地图编制工作，尽可能实现空间信息的标准化处理。 2008年，莫利塞大区环境遗产办公室将该项目的全部纸质档案移交我方。该办公室此前已留存部分片区的专题地图扫描件，对于缺失的扫描资源或不适用于地理配准的现有扫描件，我方均完成了重新扫描工作。 本次PTPAAV地图编制所用的制图基准为1:25000比例尺的IGM（意大利军事地理研究所）底图。
