Description
The Provincial Technical Map is produced with the intention of being a cartography useful for the design activities of extensive works on the territory and urban planning, hence the name 'technical map'. It is also suitable as a basis for various types of thematic maps.
The 2020 edition is currently available and downloadable, updated and based on the LIDAR survey (215 plates at a scale of 1:10,000).
With Resolution No. 102 of 29 January 2010 'Definition of the Strategic Guidelines for the evolution of the Environmental and Territorial Information System (SIAT) and amendments to Provincial Council Resolution No. 2664/2008', work had begun on the creation of the new Provincial Technical Map, at a scale of 1:10,000.
The main difference between the two maps (the original CTP00 and CTP20) is that the new, updated CTP is based on the LIDAR survey, and is therefore homogeneous over the entire provincial territory, while the CTP00 is based on two different aerophotogrammetric flights (1998 and 2004) and was drawn up in three batches managed by three different firms, with the related problem of mosaicing the entire provincial territory.
The above-mentioned resolution provides for the activities to be coordinated by the SIAT secretariat and carried out operationally by the Geological Service, favouring, in the first phase, the themes related to the hazard map.
In this context, the SIAT secretariat has decided on the following themes to be radically or partially updated (*) during the years from 2010 to 2020:
TOPONOMASTICS
- toponym inscriptions (*)
VIABILITY
- addition of numerous new works throughout the province
- cableways
- SAT trails

- single trees (*), shrubs (*), pastures (*)
QUARRIES AND MINES

- rockfall barriers (*)
- tome valleys (*)
- adhesion nets (*)
ADMINISTRATIVE BOUNDARIES
- cadastral/municipal/provincial boundaries
For the dressing of the new CTP, the information from the CTP00 was used for the non-updated thematic areas and therefore locally there are still some inconsistencies that will be resolved with the progressive updating of all the thematic areas.
Another important aspect of the new cartography lies in the processing of the basic data that make it up, which, for the first time ever, are provided by the various provincial structures and not by external firms. In this case, there is a direct empowerment of the structures, which will also have to guarantee its updating over time.
The work carried out was to make the new database consistent with what is represented on the Charter.
The aim of this method is to arrive at a database for the CTP themes that is consistent with what is depicted on the map and that allows it to be updated dynamically.
Downloading the data
The following material can be downloaded for each of the 215 tables at a scale of 1:10,000 that make up the entire provincial map:
1. PDF image of the table complete with legend;
2. TIFF image of the georeferenced table in black and white;
3. ZIP file containing all the vector themes of the table plus an MXD project with corrected symbology.
