In the past days we are asked to give a lesson about our contribution to the project at the Liceo Scientifico Bertrand Russel of Cles (TN, Italy). In order to prepare some data for the event, I started to work on a 3D map of the underwater surface of the lake and, to collect material for different ArcheOS videotutorials I recorded almost the complete process. For this reason I start today a series of "minipost" to publish this material, hoping that this will be useful for some readers.
In this first minipost I will write about open geodata, which are very important for archaeologists, but also for other professionals. Before to enter the topic, I have to say that we live and work (fortunately for us) in a Italian province (Trentino) which is sensible to this matter (open data). If you can understand Italian, you should read +Maurizio Napolitano's blog, one of the real expert in this field currently working at the Fondazione Bruno Kessler.
During the Project Tovel I needed geographical open data to set up the GIS system with some basic cartography. More specifically I started with the "Carta Tecnica Provinciale" (a technical map of the province), which I downloaded form the "Portale Cartografico Trentino" of the S.I.A.T. (Sistema Informativo Ambientale e Territoriale of the Province Trentino). As you can read in the portal (sorry, just Italian), the C.T.P. (Carta Tecnica Provinciale) is available Under the Creative Commons Attribution 2.5 terms.
The videotutorial you can see below just show the simple process to access and download these data (in raster or vector) form the webgis service.
I hope this first post was youseful for some of you, have a nice day!
