MOLISEDB.GIS.MO_qualit_agr_natur_poly_3

The feature class MO_qualit_agr_natur_poly_3 — represents the natural qualitative elements of agricultural interest — area type — acquired from the map of the quality characteristics of the terirtory 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（feature class）MO_qualit_agr_natur_poly_3 代表具有农业研究价值的自然定性要素——区域类型，其数据源自比例尺为1:25000的区域质量特征地图。PTPAAV（《瓦斯塔区域环境国土规划》，Territorial Environmental Country Plan of Area Vasta）是一系列专题地图，自1989年启动编制，于1991年11月底完成并获批，共划分为8个区域，覆盖莫利塞大区（Molise Region）全域。本项目由多组技术团队协作完成：其中协调小组通过通告明确了全套制图规范，涵盖绘图笔尖粗细、油墨类型与所用色调等内容；另有8个设计小组分别对应各区域开展制图工作，各小组尽可能对空间信息进行标准化处理。此项工作的纸质档案于2008年由莫利塞大区环境遗产办公室（Environmental Heritage Office of the Molise Region）移交我方。该办公室此前已完成部分区域相关专题地图的扫描工作，对于缺失的档案以及扫描质量不适用于地理配准的档案，团队均重新进行了扫描。本次制图工作组编制PTPAAV专题地图所采用的基础底图，为比例尺1:25000的IGM地图。
