Construction of a webgis tool based on a gis semiautomated processing for the localization of p2g plants in sicily (Italy)
2021
The recent diffusion of RES (Renewable Energy Sources), considering the electric energy produced by photovoltaic and wind plants, brought to light the problem of the unpredictable nature of wind and solar energy. P2G (Power to Gas) implementation seems to be the right solution, transforming curtailed energy in hydrogen. The choice of the settlement of P2G plants is linked to many factors like the distances between the gas grid and the settlement of RES plants, the transportation networks, the energy production, and population distribution. In light of this, the implementation of a Multi-Criteria Analysis (MCA) into a Geographic Information System (GIS) processing represents a good strategy …
Automated system for data acquisition and monitoring
2017
The Environmental management has become, with the development of human society a very important issue. There have been multiple systems that automatically monitors the environment. In this paper we propose a system that integrates GIS software and data acquisition software. In addition the proposed system implements new AHP multicriteria method that can get an answer online on each pollutant influence on limited geographical area in which the monitors. Factors pollutants of limited geographical areas are taken automatically by specific sensors through acquisition board. Labview software, with virtual instrument created by transferring them into a database Access. Access database they are ta…
El uso de SIG de software libre en una práctica de Biología y Geología de 4º de ESO: los ecosistemas.
2016
Para consolidar el conocimiento del bloque del currículo de Biología y Geología de 4º de la E.S.O. (Educación Secundaria Obligatoria) relacionado con los ecosistemas, hemos desarrollado una metodología docente basada en los Sistemas de Información Geográfica (SIG), en la que el objetivo de los estudiantes es crear un shapefile con atributos espaciales e información ecológica sobre los distintos Parques Nacionales de España mediante su digitalización. Se ejemplifica con el procedimiento concreto del Parque Nacional de Doñana. A través del SIG, con un software gratuito para el centro, se aumenta la interactividad del estudiante con la asignatura, se desarrolla la creatividad y se mejora la ca…
Google Earth geo-education resources: A transnational approach from Ireland, Iceland, Finland, and Norway
2012
The Northern Environmental Education Development (NEED) project was a transnational geo-education resource development initiative cooperated by four European countries: Ireland, Finland, Norway, and Iceland. NEED supported the development of novel geological information resources, and the establishment of geoeducation networks in the four project regions. An analysis of the national geography and science curriculum in each region was conducted. This analysis identifi ed which geographic learning skills were common to each curriculum. The development of innovative geographic information system (GIS) resources to help support the development of geographic skills was considered a potentially v…
How the AIS can Improve its Contributions to the UN’s Sustainability Development Goals: Towards A Framework for Scaling Collaborations and Evaluating…
2021
In March, 2020, the coronavirus disease of 2019 (COVID-19) pandemic affected the information systems (IS) higher education community (along with the rest of the world) profoundly. Higher education institutes across the world had to quickly shift to online courses. In some cases, faculty had to transition their courses in only days. In response, the Communications of the Association for Information Systems launched a special issue on COVID-19, learning, pedagogy, and educational systems to provide a forum for IS faculty around the world to share effective practices and opinions regarding the long-term consequences of the COVID-19 pandemic on IS education. This paper serves as the editorial f…
Investigating effects in GNSS station coordinate time series
2014
The vertical and horizontal displacements of the Earth can be measured to a high degree of precision using GNSS. Time series of Latvian GNSS station positions of both the EUPOS®-Riga and LatPos networks have been developed at the Institute of Geodesy and Geoinformation of the University of Latvia (LU GGI). In this study the main focus is made on the noise analysis of the obtained time series and site displacement identification. The results of time series have been analysed and distinctive behaviour of EUPOS®-Riga and LatPos station coordinate changes have been identified. The possible dependences of GNSS station coordinate distribution on EPN station problems, seismic activity of some area…
Land Information Systems for Development (LIS4D): A Neglected Area within ICT4D Research?
2015
The lack of accurate information about land and land ownership is a major challenge for developing countries. Despite the important role of information systems (IS) in overcoming such weaknesses, the research area of land information systems has been scattered within IS, as well as within the area of information and communication technologies for development (ICT4D). Based on a literature review research contributions are synthesized into four main perspectives, namely Development, eGovernment, Geographical information systems (GIS) and Land law, policy, and administration. These perspectives form the basis for the suggested conceptualization of the land information systems for development …
Environmental Features Associated With Older Adults' Physical Activity in Different Types of Urban Neighborhoods.
2020
The authors studied associations of nature- and infrastructure-based features with physical activity (PA) in different urban neighborhood types; 848 community-dwelling people aged 75–90 years reported PA and three perceived nature-based destinations and seven infrastructure-based features as outdoor mobility facilitators. Neighborhood type was defined using a geographic information system based on proximity to central service areas and residential density (city center, subcenter, and dense and dispersed areas outside centers). PA was higher in dense areas and the city center. Binary logistic regression showed that perceiving nature-based destinations increased the odds for higher PA in the …
GIS-data related route optimization, hierarchical clustering, location optimization, and kernel density methods are useful for promoting distributed …
2019
Currently, geographic information system (GIS) models are popular for studying location-allocation-related questions concerning bioenergy plants. The aim of this study was to develop a model to investigate optimal locations for two different types of bioenergy plants, for farm and centralized biogas plants, and for wood terminals in rural areas based on minimizing transportation distances. The optimal locations of biogas plants were determined using location optimization tools in R software, and the optimal locations of wood terminals were determined using kernel density tools in ArcGIS. The present case study showed that the utilized GIS tools are useful for bioenergy-related decision-maki…
Student-teachers’ use ofGoogle Earthin problem-based geology learning
2011
Geographical Information Systems (GIS) are adequate for analyzing complex scientific and spatial phenomena in geography education. Google Earth is a geographic information tool for GIS-based learning. It allows students to engage in the lesson, explore the Earth, explain what they identify and evaluate the implications of what they are learning. This paper introduces one example of using Google Earth for problem-based learning processes in teacher education. Student-teachers’ geographical thinking was analyzed during the study process. We have found that although student-teachers have inadequate skills to use information and communication technology, the use of Google Earth improved student…
