Smart environment monitoring through micro unmanned aerial vehicles

In recent years, the improvements of small-scale Unmanned Aerial Vehicles (UAVs) in terms of flight time, automatic control, and remote transmission are promoting the development of a wide range of practical applications. In aerial video surveillance, the monitoring of broad areas still has many challenges due to the achievement of different tasks in real-time, including mosaicking, change detection, and object detection. In this thesis work, a small-scale UAV based vision system to maintain regular surveillance over target areas is proposed. The system works in two modes. The first mode allows to monitor an area of interest by performing several flights. During the first flight, it creates an incremental geo-referenced mosaic of an area of interest and classifies all the known elements (e.g., persons) found on the ground by an improved Faster R-CNN architecture previously trained. In subsequent reconnaissance flights, the system searches for any changes (e.g., disappearance of persons) that may occur in the mosaic by a histogram equalization and RGB-Local Binary Pattern (RGB-LBP) based algorithm. If present, the mosaic is updated. The second mode, allows to perform a real-time classification by using, again, our improved Faster R-CNN model, useful for time-critical operations. Thanks to different design features, the system works in real-time and performs mosaicking and change detection tasks at low-altitude, thus allowing the classification even of small objects. The proposed system was tested by using the whole set of challenging video sequences contained in the UAV Mosaicking and Change Detection (UMCD) dataset and other public datasets. The evaluation of the system by well-known performance metrics has shown remarkable results in terms of mosaic creation and updating, as well as in terms of change detection and object detection

Review on the Application of Geographical Information Systems (GIS) in Veterinary Medicine

Geographical Information System (GIS) is a computer system that displays stored digital data developed over the last decade. GIS is a platform consisting of hardware, software, data and people and encompasses a fundamental and universally applicable set of value-added tools for input, transforming, data management and storage, analyzing, and output information that are geographically referenced. GIS can be applied to different veterinary activities. It can help to understand and explain the dynamics and spreading pattern of a disease and increase the speed of response in the case of a disease emergency. In an outbreak of a disease it could make the management of the situation easier, and it could also provide a tool to evaluate different strategies to prevent the spread of infectious diseases. The following areas in which GIS and special GIS-functions could be incorporated are presented: surveillance and monitoring of animal diseases, recording and reporting information, epidemic emergency, modeling disease spread, and planning control strategies. The technology has many features which make it ideal for use in animal disease control, including the ability to store information relating to demographic and causal factors and disease incidence on a geographical background, and a variety of spatial analysis functions

Fine-grained traffic state estimation and visualisation

Tools for visualising the current traffic state are used by local authorities for strategic monitoring of the traffic network and by everyday users for planning their journey. Popular visualisations include those provided by Google Maps and by Inrix. Both employ a traffic lights colour-coding system, where roads on a map are coloured green if traffic is flowing normally and red or black if there is congestion. New sensor technology, especially from wireless sources, is allowing resolution down to lane level. A case study is reported in which a traffic micro-simulation test bed is used to generate high-resolution estimates. An interactive visualisation of the fine-grained traffic state is presented. The visualisation is demonstrated using Google Earth and affords the user a detailed three-dimensional view of the traffic state down to lane level in real time

Microreact: visualizing and sharing data for genomic epidemiology and phylogeography

Visualization is frequently used to aid our interpretation of complex datasets. Within microbial genomics, visualizing the relationships between multiple genomes as a tree provides a framework onto which associated data (geographical, temporal, phenotypic and epidemiological) are added to generate hypotheses and to explore the dynamics of the system under investigation. Selected static images are then used within publications to highlight the key findings to a wider audience. However, these images are a very inadequate way of exploring and interpreting the richness of the data. There is, therefore, a need for flexible, interactive software that presents the population genomic outputs and associated data in a user-friendly manner for a wide range of end users, from trained bioinformaticians to front-line epidemiologists and health workers. Here, we present Microreact, a web application for the easy visualization of datasets consisting of any combination of trees, geographical, temporal and associated metadata. Data files can be uploaded to Microreact directly via the web browser or by linking to their location (e.g. from Google Drive/Dropbox or via API), and an integrated visualization via trees, maps, timelines and tables provides interactive querying of the data. The visualization can be shared as a permanent web link among collaborators, or embedded within publications to enable readers to explore and download the data. Microreact can act as an end point for any tool or bioinformatic pipeline that ultimately generates a tree, and provides a simple, yet powerful, visualization method that will aid research and discovery and the open sharing of datasets

Archaeological site monitoring: UAV photogrammetry can be an answer

During archaeological excavations it is important to monitor the new excavated areas and findings day by day in order to be able to plan future excavation activities. At present, this daily activity is usually performed by using total stations, which survey the changes of the archaeological site: the surveyors are asked to produce day by day draft plans and sections which allow archaeologists to plan their future activities. The survey is realized during the excavations or just at the end of every working day and drawings have to be produced as soon as possible in order to allow the comprehension of the work done and to plan the activities for the following day. By using this technique, all the measurements, even those not necessary for the day after, have to be acquired in order to avoid a ‘loss of memory'. A possible alternative to this traditional approach is aerial photogrammetry, if the images can be acquired quickly and at a taken distance able to guarantee the necessary accuracy of a few centimeters. Today the use of UAVs (Unmanned Aerial Vehicles) can be considered a proven technology able to acquire images at distances ranging from 4 m up to 20 m: and therefore as a possible monitoring system to provide the necessary information to the archaeologists day by day. The control network, usually present at each archaeological site, can give the stable control points useful for orienting a photogrammetric block acquired by using an UAV equipped with a calibrated digital camera and a navigation control system able to drive the aircraft following a pre-planned flight scheme. Modern digital photogrammetric software can solve for the block orientation and generate a DSM automatically, allowing rapid orthophoto generation and the possibility of producing sections and plans. The present paper describes a low cost UAV system realized by the research group of the Politecnico di Torino and tested on a Roman villa archaeological site located in Aquileia (Italy), a well-known UNESCO WHL site. The results of automatic orientation and orthophoto production are described in terms of their accuracy and the completeness of information guaranteed for archaeological site excavation managemen

Privacy and Geospatial Technologies

This research examines the role of geospatial and ancillary technologies in the erosion of privacy in contemporary society. The development of Remote Sensing, GIS, and GPS technologies are explored as a means of understanding both their current and predicted uses and capabilities. Examination is also made of the legal basis and current status of privacy rights in the United States. Finally, current and predicted uses and capabilities of geospatial and ancillary technologies are critically examined in light of existing privacy protections as a means of determining the ways in which these technologies are impacting privacy currently and what their effects may be in the future

Mapping and enumerating houses and households to support malaria control interventions on Bioko Island.

BACKGROUND: Housing mapping and household enumeration are essential for the planning, implementation, targeting, and monitoring of malaria control interventions. In many malaria endemic countries, control efforts are hindered by incomplete or non-existent housing cartography and household enumeration. This paper describes the development of a comprehensive mapping and enumeration system to support the Bioko Island Malaria Control Project (BIMCP). RESULTS: A highly detailed database was developed to include every housing unit on Bioko Island and uniquely enumerate the associated households residing in these houses. First, the island was divided into a virtual, geo-dereferenced grid of 1 × 1 km sequentially numbered map-areas, each of which was in turn subdivided into one hundred, 100 × 100 m sequentially numbered map-sectors. Second, high-resolution satellite imagery was used to sequentially and uniquely identify all housing units within each map-sector. Third, where satellite imagery was not available, global positioning systems (GPS) were used as the basis for uniquely identifying and mapping housing units in a sequential manner. A total of 97,048 housing units were mapped by 2018, 56% of which were concentrated in just 5.2% of Bioko Island's total mapped area. Of these housing units, 70.7% were occupied, thus representing uniquely identified households. CONCLUSIONS: The housing unit mapping and household enumeration system developed for Bioko Island enabled the BIMCP to more effectively plan, implement, target, and monitor malaria control interventions. Since 2014, the BIMCP has used the unique household identifiers to monitor all household-level interventions, including indoor residual spraying, long-lasting insecticide-treated nets distribution, and annual malaria indicator surveys. The coding system used to create the unique housing unit and household identifiers is highly intuitive and allows quick location of any house within the grid without a GPS. Its flexibility has permitted the BIMCP to easily take into account the rapid and substantial changes in housing infrastructure. Importantly, by utilizing this coding system, an unprecedented quantity and diversity of detailed, geo-referenced demographic and health data have been assembled that have proved highly relevant for informing decision-making both for malaria control and potentially for the wider public health agenda on Bioko Island

Flaunting it on Facebook: Young adults, drinking cultures and the cult of celebrity

This population has also rapidly increased their use of new social networking technologies (e.g. mobile camera/ video phones; Facebook and YouTube) and are said to be obsessed with identity, image and celebrity. This research project explored the ways in which new technologies are being used by a range of young people (and others, including marketers) in drinking practices and drinking cultures in Aotearoa/NZ. It also explored how these technologies impact on young adults’ behaviours and identities, and how this varies across young adults of diverse ethnicities (Maori [indigenous people of NZ], Pasifika [people descended from the Pacific Islands] and Pakeha [people of European descent]), social classes and genders. We collected data from a large and diverse sample of young adults aged 18-25 years employing novel and innovative methodologies across three data collection stages. In total 141 participants took part in 34 friendship focus group discussions (12 Pakeha, 12 Maori and 10 Pasifika groups) while 23 young adults showed and discussed their Facebook pages during an individual interview that involved screencapture software and video recordings. Popular online material regarding drinking alcohol was also collected (via groups, interviews, and web searches), providing a database of 487 links to relevant material (including websites, apps, and games). Critical and in-depth qualitative analyses across these multimodal datasets were undertaken. Key findings demonstrated that social technologies play a crucial role in young adults’ drinking cultures and processes of identity construction. Consuming alcohol to a point of intoxication was a commonplace leisure-time activity for most of the young adult participants, and social network technologies were fully integrated into their drinking cultures. Facebook was employed by all participants and was used before, during and following drinking episodes. Uploading and sharing photos on Facebook was particularly central to young people’s drinking cultures and the ongoing creation of their identities. This involved a great deal of Facebook ‘work’ to ensure appropriate identity displays such as tagging (the addition of explanatory or identifying labels) and untagging photos. Being visible online was crucial for many young adults, and they put significant amounts of time and energy into updating and maintaining Facebook pages, particularly with material regarding drinking practices and events. However this was not consistent across the sample, and our findings revealed nuanced and complex ways in which people from different ethnicities, genders and social classes engaged with drinking cultures and new technologies in different ways, reflecting their positioning within the social structure. Pakeha shared their drinking practices online with relatively little reflection, while Pasifika and Maori participants were more likely to discuss avoiding online displays of drinking and demonstrated greater reflexive self-surveillance. Females spoke of being more aware of normative expectations around gender than males, and described particular forms of online identity displays (e.g. moderated intake, controlled selfdetermination). Participants from upper socio-economic groups expressed less concern than others about both drinking and posting material online. Celebrity culture was actively engaged with, in part at least, as a means of expressing what it is to be a young adult in contemporary society, and reinforcing the need for young people to engage in their own everyday practices of ‘celebritising’ themselves through drinking cultures online. Alcohol companies employed social media to market their products to young people in sophisticated ways that meant the campaigns and actions were rarely perceived as marketing. Online alcohol marketing initiatives were actively appropriated by young people and reproduced within their Facebook pages to present tastes and preferences, facilitate social interaction, construct identities, and more generally develop cultural capital. These commercial activities within the commercial platforms that constitute social networking systems contribute heavily to a general ‘culture of intoxication’ while simultaneously allowing young people to ‘create’ and ‘produce’ themselves online via the sharing of consumption ‘choices’, online interactions and activities
