CAPACITY BUILDING FOR RS & GIS TECHNOLOGY APPLICATIONS: STUDENT REMOTE SENSING AND GEOSPATIAL PROGRAMME IN ACADEMIC INSTITUTIONS

Abstract. Digital India program aims to transform India into a knowledge economy with Smart Cities / Smart Villages etc. It depends significantly on Remote Sensing (RS) and Geographic Information Systems (GIS). It requires enormous computing Infrastructure and RS-GIS trained professionals along with Information and Communications Technology (ICT). Satellite based Earth Observation (EO) data volumes are increasing at a rate of several Terabytes a Day in heterogeneous formats (different spatial and temporal resolutions in optical, thermal and microwave). The recent trends towards free and open access policy creates unprecedented opportunities for both industrial and academic research communities for Big Data applications.During the last decade, Engineering Institutions across the nation have improved significantly in terms of high end computing, Wi-Fi campuses and qualified faculty to help students. Agricultural Universities/Colleges are also making extensive use of RS-GIS technology. Many research papers are also being published by students from Engineering / Agricultural Institutions in the domain of RS–GIS. Here lies the scope for enhanced collaboration between ISRO / Industry and Academia in the form of Student Remote Sensing and Geospatial programme (SRSGP) for scaling up operational services to sustain Digital India and boost the Geospatial Readiness Index of the nation. It will expand the hands-on experience of the student community and enrich their job-readiness in the industry and lead to development of trained RS-GIS professionals. It has the potential to make Digital India the global destination for RS-GIS applications similar to how Y-2K made India the global IT-destination.

In recent years, interest in BIM and GIS applications in civil engineering has been growing. For bridge engineering, BIM/GIS applications such as simulation, visualization, and secondary development have been used to assist practitioners in managing bridge construction and decision-making, including selection of bridge location maintenance decisions. In situ 3D modelling of existing bridges with detailed images from UAV camera has allowed engineers to conduct remote condition assessments of bridges and decide on required maintenance actions. Several studies have investigated the applications of BIM/GIS technology on bridge projects. However, there has been limited focus on reviewing the outcomes of these studies to identify the limitations of BIM and GIS applications on bridge projects. Therefore, the aim of this study was to review the research on BIM/GIS technology applications in bridge projects over the last decade. Using a systematic review process, a total of 90 publications that met the inclusion criteria were reviewed in this study. The review identified the state-of-the-art methods of BIM and GIS applications, respectively, at the planning and design, construction, and operation and maintenance phases of bridge projects. However, the findings point to segregated application of BIM and GIS at all phases of bridge projects. The findings of this study will contribute to guiding practitioners in selecting appropriate BIM and GIS technologies for different aspects of bridge projects.

Spot 5

In the global era, more than half of the world population live in urban area. With rapid urbanisation growth where the highest percentage concentrates in Asia, a relevant approach is needed to eliminate the possible threat that occurs after urbanisation took place; the urban sprawl. Urban sprawl is a popular term in academic discourse and has a long history but until these days, the concrete definition of this term is not yet configured. Many studies of sprawl have rooted back in non-Asian countries making the solution for sprawl is not suitable to be implemented in term of theories and practice. This research attempts to study the measurement of sprawl by using these geospatial indexes with Remote Sensing and GIS approach. The SPOT-5 images with 2.5 meters resolution were used to analyse the growth of sprawl in Kuala Lumpur metropolitan due to its high urbanisation rate. The findings show that Kuala Lumpur is a sprawling city. It is anticipated that this research will provide a new direction in urban sprawl studies and represent a robust analytic approach for characterizing urban development on the city scale at once as well as promoting a city via Remote Sensing and GIS technology.

Abstract. The expansion of data collection from remote sensing and other geographic data sources, as well as from other technology such as cloud, sensors, mobile, and social media, have made mapping and analysis more complex. Some geospatial applications continue to rely on conventional geospatial processing, where limitation on computation capabilities often lacking to attain significant data interpretation. In recent years, GPU processing has improved far more GIS applications than using CPU alone. As a result, numerous researchers have begun utilising GPUs for scientific, geometric, and database computations in addition to graphics hardware use. This paper summarizes parallel processing concept and architecture, the development of GPU geoprocessing for big geodata ranging from remote sensing and 3D modelling to smart cities studies. This paper also addresses the GPU future trends advancement opportunities with other technologies, machine learning, deep learning, and cloud-based computing.

Seismic Swarms

Abstract. Campi Flegrei caldera (Southern Italy) is one of the most hazardous volcanic complexes in the world since it is located inside the densely inhabited urban district of Naples-Pozzuoli. In the past, the caldera has produced devastating to moderate eruptions and periodically undergoes from strong to minor uplift episodes, named “bradyseism”, almost always accompanied by seismic swarms. Starting from 2005 Campi Flegrei has undergone an unrest crisis, characterized by ground uplift, localized gas emissions and seismicity, often occurring in seismic swarms. As a consequence, the monitoring activities have been progressively increasing, producing a huge amount of data, difficult to manage and match. GIS (Geographical Information System) represents a potent tool to manage great quantity of data, coming from different disciplines. In this study, we show two GIS technology applications to the seismic catalogue of Campi Flegrei. In the first one, a high-quality dataset is extracted from the GeoDatabase addressed to seismological studies that require high precision earthquake locations. In the second application, GIS are used to extract, visualize and analyse the typical seismic swarms of Campi Flegrei. Moreover, density and seismic moment distribution maps were generated for these swarms. In the last application, the GIS allow to highlight a clear variation in the temporal trend of the seismic swarms at Campi Flegrei.
