MOLISEDB.GIS.MO_pollution_lin_5

The MO_pollution_lin_5 feature class represents pollution - linear elements acquired from the pollution map at a scale of 1:25 000. The PTPAAV maps (Piano Territoriale Paese Ambientale di Vasta Area) 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 various groups of technicians, a coordination group which established through circulars the standards to be used for the drafting of the plans which ranged from the thickness of the tip of the graph to the type of screen and the shades to be used, and 8 groups one for each area, who created the maps trying to standardize the territorial information as much as possible. The hard copy 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 maps relating to some areas, the missing ones and in the case of scans that were not suitable for georeferencing, they were scanned. The cartographic basis used by the working groups for the creation of the PTPAAV maps was the IGM in 1:25,000 scale.

lineage Territorial Landscape-Environmental Plan of a Wide Area n. 5 "Northern Matese" concerns the following municipalities: Castelpetroso, Castelpizzuto, Longano, Monteroduni, Pettoranello del Molise, Sant'Agapito. The ESRI ArcGis 9.3 software with service pack 1 was used for the data acquisition process. All the tools made available by ArcGis 9.3 for data creation. In the computerization of the data relating to the landscape plans, a single Geodatabase was created with all the data, in order to correctly create and manage the entire data processing and creation flow. A UML model was not needed in Visio because the data to be acquired did not have uniform legends between the different scopes and consequently each of them had characteristics of its own. The acquisition process required the numerical transformation of the paper data relating to the information of the aforementioned area. The processing process began with the transformation of the data (*.jpg) into data (*.tif), a format that is better manageable in ArcGis. The raster files were georeferenced using ESRI ArcMap on the basis of corresponding points of the IGM 1:25000 tablets, which were loaded into the I SAA within the raster catalog of the same name in the personal geodatabase aster_Molise.mdb (original reference system ED50-UTM32). During the georeferencing phase, files with the extension (*.txt) were also saved containing the georeference points and log files containing, in addition to the latter, information relating to errors, the feature classes obtained and any annotations. The feature classes present in the GDB_2_piani_paesistici geodatabase were built starting from a raster digitization process in format (*.tif): the feature classes were initially created with ESRI ArcCatalog and subsequently completed using the tools of the Editor of ESRI ArcMap based on the georeferenced raster. For data of this type, linear, the editing phase was performed directly on the feature classes of the Geodatabase. The structure of the feature classes was organized with ESRI ArcCatalog with the creation of special fields containing the attributes of the features based on the information described in the legend, possibly organized into domains and subtypes (in the case of a hierarchical structure of the attributes), as coherent as possible with the legend on paper. Lacking substantial uniformity in the legends of the corresponding thematic maps in the various fields, it was not possible to establish valid domains for the entire Geodatabase, and in most cases each domain is used for a single field of a single feature class. The data created they have been reprojected in geographic WGS84 using IGM Verto 2000 software, which uses the grid. They have been loaded, maintaining the information structure created, through the basic functions of ArcGIS in the SVA database, on RDBMS DB2.
