“…Finally, a code was developed to build up the 3D geologic model of the bedding attitude. The code is developed in the GRASS GIS software (GRASS Development Team, 2015) and exploits the pygrass API (Zambelli et al, 2013). The tool generates a DEM of a given bedding layer (BL) starting from a bedding traces layer and a map of the interpolated bedding attitude.…”

Three-dimensional modeling of geological bodies is a useful tool for multiple applications. Such tasks are usually accomplished starting from fieldcollected data, which typically suffer from intrinsic limitations such as accessibility constraints and punctuality of data collected. In this work, we explore the reliability of photo-geological mapping from interpretation of aerial photographs in providing data useful to build up 3D geological models. The test was conducted in a 15 km 2 in Umbria, central Italy. The three-steps open source GIS procedure that outputs 3D models from photo-geological data was developed using python in GRASS GIS environment and GNU-Linux OS. We maintain that this procedure can have potential broad applications in Earth Sciences, including geological and structural analyses, up to the preliminary evaluation of potential reservoirs.

“…The main courses A rough estimate of the total number of students that attended the courses is 1700. The application of spatial data techniques to diverse scientific fields and topics has proven to be a hotbed for interdisciplinary applications; see, e.g., [34][35][36][37][38][39]. Because of the success of these courses, the DICAM introduced the same approach in doctoral courses: "Environmental data management and analysis with GIS" (2006 to the present) and "Field sampling and spatial ecological modelling" (2017).…”

Abstract:While the theory and implementation of geographic information systems (GIS) have a history of more than 50 years, the development of dedicated educational tools and applications in this field is more recent. This paper presents a free and open source software (FOSS) approach for education in the geospatial disciplines, which has been used over the last 20 years at two Italian universities. The motivations behind the choice of FOSS are discussed with respect to software availability and development, as well as educational material licensing. Following this philosophy, a wide range of educational tools have been developed, covering topics from numerical cartography and GIS principles to the specifics regarding different systems for the management and analysis of spatial data. Various courses have been implemented for diverse recipients, ranging from professional training workshops to PhD courses. Feedback from the students of those courses provides an invaluable assessment of the effectiveness of the approach, supplying at the same time directions for further improvement. Finally, lessons learned after 20 years are discussed, highlighting how the management of educational materials can be difficult even with a very open approach to licensing. Overall, the use of free and open source software for geospatial (FOSS4G) science provides a clear advantage over other approaches, not only simplifying software and data management, but also ensuring that all of the information related to system design and implementation is available.

“…In our opinion, software implementation of GIS DSSs should be carried out using mainly Open Source software [124]. In this way, after being developed for specific study cases, the software could be freely available to be tested in any other context and improved by any subject, public or private, willing to give his contribution, respecting the Open Source licences and giving proper credit to the original authors [125,126]. Since the final target of this DSS should be represented by people who are not software experts, during software development particular attention should be given to develop user-friendly graphic interface.…”

Abstract:In the Alpine environment, Man has always been directly dependent on mountain ecosystems. Social mechanisms have created specific models of governance, capable of assuring the persistence of ecosystems and their capacity to provide essential goods and services. In recent decades, however, dramatic changes have occurred, such as climate change and changes in land use. The complexity common to all linked human-natural environment systems is extremely marked in the Alpine areas and this makes it difficult to understand how resilient these systems may be. Many research questions arise, in particular as to the comprehension and quantification of the impact of changes on the capacity of ecosystems to produce goods and services in a sustainable way, and the possibility of local mechanisms of governance to adapt to both current and future changes. Reasons and effects of change are analysed from the perspective of the specific issues of governance. The importance of the Ecosystems Services (ESs) concept is acknowledged and the necessity for a dynamic assessment of ESs, taking into account people's values and expectations, is particularly stressed. Through a careful analysis of selected papers and case studies, the main gaps in current knowledge are identified and directions for further research are provided.
