MOLISEDB.GIS.MO_hydrogeological_poly_1

The feature class MO_hydrogeologica_poly_1 represents the hydrogeological 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_hydrogeologica_poly_1代表从比例尺1:25000的水文地质图中获取的水文地质要素。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，于1991年11月底完成并获批，按辖区划分为共计8个区域，覆盖大区管辖范围。此项工作由多组技术人员协同完成：其中协调组通过通告明确制图规范，涵盖绘图笔尖粗细、网线类型及所用色彩层次等内容；另有8个分区设计组，每组负责一个区域，在制图过程中尽可能统一空间信息标准。此项工作的相关资料于2008年由莫利塞大区环境遗产办公室移交我方。该办公室此前已完成部分区域相关专题图件的扫描工作，针对缺失图件以及不适用于地理配准的扫描件，我方已重新完成扫描。各工作组编制PTPAAV地图时所采用的制图基底为比例尺1:25000的IGM地图。
