GIS Decalogue

These  points would propose how to to a GIS environment. Any suggestion will be appreciated

How find (and where) GIS data

These notes are for the sole purpose of describing the GIS data discovery proces

An open source 'approach' for the MoMoWo GIS database

Starting from an idea of a participatory stream of knowledge, MoMoWo project has represented the field in which try to share information using free and open source software, tools and databases only. This is why we have created a WEBGIS about Women's creativity using LibreOffice, QGIS and qgis2web. In fact, a WEBGIS system is the best way to publish and share knowledge all around the world

Source and Data for the Analysis of the Metropolitan Territory with GIS Tools: A Critical Review Between Commercial and Open Access Tools

This contribution addresses the issue of the availability and accessibility of data for urban and regional studies. After an initial part in which tools and arguments are provided to frame the open data paradigm, the second part proceeds with the simulation of a GIS-based study on a territory of the Metropolitan City of Turin aimed at supporting post-COVID territorial planning, highlighting the areas in which there is a lack of data, the difficulty of access, such as in health care, or the obligation to have to use commercial data. In the last part, the results of the study are discussed, and the issue of the importance of the construction of digital models (digital twins) capable of receiving and processing data of different sources, and how these models should be developed according to an open and non-commercial paradigm

Anamorphic Cartograms and Environmental Risk Analysis

Both Geography and Statistics use graphical representations. Information Technology has enhanced the visualization of data, beyond the traditional aspects, to such an extent that we can nowadays speak of an “image society”. Traditional thematic mapping also shows transformations of a variable over time, linking the geographical datum to the time variable. For some decades now a number of cartograms have been in use, for which the base area is displaced as a function of a particular factor, these are known as anamorphic cartograms. An anamorphic map is easier to read and may give an overview of a geographic whole
