Monitoring event attendance using a combination of traditional and advanced surveying tools
2018
This paper will describe the research stages and tools used for monitoring participants’ attendance at the European Researchers’ Night, held in Palermo in September 2017. A combination of traditional survey instruments and new technologies was effected in order to analyse participants’ behaviour during the event. The results derived from these different data sources were also integrated and analysed in order to evaluate the success of the event from social and economic points of view. Data relating to participants’ mobility during the event will be described and clusters of participants proposed, based on their mobility behaviour.
Il monitoraggio topografico della cattedrale di Agrigento con metodi tradizionali
2014
L’oggetto del presente lavoro è il monitoraggio della cattedrale di San Gerlando di Agrigento, duomo eretto tra i secoli XI e XII, che sorge nella parte più alta della collina di Girgenti. Lo studio è significativo poiché, nel corso dei secoli la costruzione è stata soggetta a interventi di ristrutturazione e di consolidamento, resi necessari dai danni arrecati da frane che, in più occasioni, hanno coinvolto il territorio su cui essa sorge. Dal 2010 la chiesa è chiusa al culto per copiosi eventi franosi e idrogeologici che hanno allarmato ulteriormente anche la Protezione Civile. A seguito di questi eventi è stata avviata una campagna di indagini e monitoraggi con il fine della caratterizza…
Rilievo integrato presso il Borgo Schirò (PA)
2013
Il lavoro qui presentato consiste in un rilievo integrato (Topografico/GPS statico/NRTK/Laser Scanner) di un piccolo contesto extraurbano siciliano, Borgo Schirò, noto per le vicende storiche che portarono alla sua costruzione a seguito dell’emanazione della legge n.1 del 2 gennaio 1940, per il superamento del latifondo. Data la natura varia degli elementi da rilevare (edifici, arredo urbano, strade) sono state adottate tecniche di acquisizione diversificate per ognuno di essi, le quali, in forma integrata, hanno permesso un utile confronto finale degli elaborati prodotti, offrendo la possibilità di effettuare analisi qualitative altamente accurate su singoli casi strutturali ed elevati gra…
Análisis del comportamiento espacio-temporal intradestino mediante GPS : Una aproximación de los visitantes independientes de crucero en la ciudad de…
2020
El presente trabajo tiene como objetivo profundizar en el análisis de los patrones de comportamiento espacio-temporal de los visitantes en destino, una escala de trabajo insuficientemente desarrollada. La investigación aplica un enfoque multimétodo, que combina el uso de GPS con una encuesta, al conocimiento de los patrones espaciales de los cruceristas que visitan la ciudad de Valencia de manera independiente. Los resultados obtenidos evidencian la polarización de los flujos en el centro histórico de la ciudad, dentro de un patrón mayoritario de único nodo, una dinámica que conviene gestionar adecuadamente para prevenir la congestión y poner en valor otros atractivos urbanos. La redistribu…
Walking tourism in urban destinations: some preliminary results from a survey in Malaga with gps-based technologies
2018
Walking tourism in urban destinations can be defined as a sequence of day visits and/or a sequence of walking tours. In this work, GPS tracking data on spatio-temporal behaviour of walking tourists in Malaga are reported as case study. Malaga is a booming tourist destination characterized by a city centre, particularly suitable for a pedestrian visit. From 22nd January to 19th March 2018 for a total period of 41 days, a survey was carried out with a specific protocol: 103 interviews were conducted and 101 GPS valid tracks were collected. Walking tourists were systematically sampled, starting from the population of all tourists staying in the surveying day at some selected hotels in the city…
New Technologies and tourist mobility: a brief review of some case studies
2013
Traditional tourism statistics present several lacks in detecting tourists’ activities in space-time dimensions, due to their administrative nature, the increasing mobility of tourists and their independence in organizing trips. Since this information is fundamental for the destination management, the need to find new methods for collecting data concerning tourist activities emerges. Then, from the early years of new millennium, several researchers started to study and test the efficiency and the effectiveness of existing new technologies, such as GPS or Mobile Phone, to detect the paths followed by tourists and outline the features of tourist mobility.
STUDIO METODOLOGICO PER LA REALIZZAZIONE DI UNA RETE DI MONITORAGGIO FRANE IN AREE URBANIZZATE: IL CASO DI POGGIOREALE
2007
The goal of this work is to illustrate a methodology aimed at planning a monitoring network in urban areas affected by hydrogeological instability phenomena. The monitoring network will provide a continuous collection of data and their transmission through a Global Position System (GPS) to a central collecting and processing office. The monitoring of an area prone to high landslide risk, as could be any urban area (the town of Poggioreale in our study case), should take into consideration the collection of data relevant both for the knowledge of the landslide features as well as for the planning of reclamation action. At the same time it would also seem opportune to collect data relating to…
GeoNET: WebGIS of a GNSS Permanent Network
2009
In Sicily, from 2005 to 2007, a research group at the Dipartimento di Rappresentazione, DIRAP (University of Palermo) has realized a Global Navigation Satellite System (GNSS) network for real time positioning (Network Real Time Kinematic –NRTK), activity founded by “Minister of Instruction, University and Scientific Research” (MIUR) as “National Interest Research Program” PRIN2005 entitled "Networks of permanent GPS stations for the survey in real time control and use of emergency". The data-base contains different kind of information both general on the network and positional. Positional information can be useful for two types of survey applications: static survey with post-processing of d…
Walking tourism in Malaga: a pilot survey to explore tourism behaviours with a GPS approach

Georeferenced cartography dataset of the La Fossa crater fumarolic field at Vulcano Island (Aeolian Archipelago, Italy): conversion and comparison of…
2011
The present study illustrates the procedures applied for the coordinate system conversion of the historical fumarole positions at La Fossa crater, to allow their comparison with newly acquired global positioning system (GPS) data. Due to the absence of ground control points in the field and on both the old Gauss Boaga and the new UTM WGS 1984 maps, we had to model the transformation errors between the two systems using differential GPS techniques. Once corrected, the maps show a residual Easting shifting, due to erroneous georeferencing of the original base maps; this is corrected by morphological comparative methods. The good correspondence between the corrected positions of the historical…
