MOLISEDB.GIS.MO_risk_hydrogeo_lin_5

The feature class MO_risk_hydrogeo_lin_5 represents the hydrological risk — linear elements acquired from the hydrogeological map at 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_risk_hydrogeo_lin_5代表水文风险——即从比例尺1:25000的水文地质图中提取的线性要素。 PTPAAV（Territorial Environmental Country Plan of Area Vasta，瓦斯塔地区国土环境规划）为一系列专题地图，自1989年启动编制，1991年11月底完成并获批，按辖区划分为8个区域，覆盖莫利塞大区全域。 该项工作由多组技术人员协作完成：协调组通过发布通告明确了制图全流程的统一标准，涵盖绘图笔尖粗细、绘图耗材类型及色调选用规范等；另设8个分区设计组，每组负责对应一个区域，在地图编制过程中尽可能实现空间信息的标准化。 2008年，莫利塞大区环境遗产办公室将该项工作的全部文档资料移交我方。该办公室此前已留存部分区域相关专题图件的扫描件；对于缺失的图件，以及扫描质量不符合地理配准要求的图件，我方均重新完成了扫描。 本次编制PTPAAV地图所采用的制图基底为比例尺1:25000的IGM（Istituto Geografico Militare，意大利军事地理测绘院）官方制图资料。
