StudMap 3.0 : an interoperable web-based platform for geospatial data offers in academic life

Dissertation submitted in partial fulfilment of the requirements for the Degree of Master of Science in Geospatial TechnologiesGeographic Information Systems has now entered the realm of web and yields for feasible solutions to balance the technology offers with the users’ needs to share, access and explore the massive amounts of geodata available. Challenges occur when moving forward from old 2D platforms towards innovative and integrated webGIS systems that align functionality with the necessity to grant a complete understanding of the surrounding reality. 3D space responds to this but, however, stands only at the beginning of its era and cannot yet reach the development of 2D web integration. Research is now aiming at possible webGIS solutions to adapt to the special structure imposed by 3D data. In this context, this thesis focuses on designing an architecture for 2D and 3D geospatial data integration on a student-oriented web platform. This concept was further delivered and validated through a real case scenario – Studmap 3.0, a webGIS platform to serve the students of the University of Muenster in their academical life. The portal currently grants availability of geospatial data and web services of regional interest in a smart GIS environment that allows access and comparison of official services with own data. The implementation of Studmap 3.0 aided in the continuous improvement of the proposed architecture model and developed under a design science research cycle that reached its end once the final approval of its users was attained via a usability evaluation. Final strengths and drawbacks of the proposed architecture were ultimately identified together with an expert usability evaluation and a lab-based usability test of the resulting portal interface suitability for academic use. The results fall under the acceptable range with an 83.75 score for the System Usability Scale standardized questions when addressed to experts and a score of 83.87 when addressed to students. For the open-ended questions, the interface received an overall positive critique. A summary of future participants’ opinion on the benefits, drawbacks and proposed improvements was also delivered. Peers interested in similar concepts can use both this model and its final remarks as a reference for their work

The database structure is based on the Dublin Core metadata standard. The information system is designed to integrate and make interoperable digital resources, to ensure standardized and complex indexing, and to support advanced retrieval, according to the standards in use. The geolocation of the resources in a GIS environment can display query results in the Google Earth environment

Web-based PPGIS application for participatory spatial planning in context of bikeability

Dissertation submitted in partial fulfilment of the requirements for the Degree of Master of Science in Geospatial TechnologiesThe spatial planning processes are complex and require public participation to get insights about important problems and development of the neighborhood from the communities during final decision-making. The traditional participatory methods offer limited two-way communication just inform the public rather than to obtain suggestions from them and few public can participate due to time & location restrictions. Due to low public empowerment, they do not know how their participation can influence the spatial planning and decision-making process. This study tries to design and develop the web-based Public Participation GIS application with the integration of the internet, public participation, and GIS technologies to increase public participation during spatial planning and decision-making to overcome the limitations of traditional participatory methods. The web-based PPGIS application development is based on open-source technologies and allows the participants to visualize spatial data layer, perform spatial analyses and contribute to increasing and improving the bikeability of the city. The user study experiment is conducted to evaluate the usability and usefulness of the application. The evaluation results show that the web-based PPGIS application is easy to use with a System Usability Scale (SUS) score of 84.6 and an effective approach to increase public engagement and give suggestions on the spatial planning process and decision making

The Development of Web3D-based Open-pit Mine Monitoring System

Large-scale open-pit mines are critical infrastructure for acquiring natural resources. However, this type of mine can experience environmental and safety problems during operations and thus requires continuous monitoring. In this study, a web three-dimensional(3D)-based monitoring system is constructed using geospatial information open platform and open-source geospatial information software which targets open-pit mines in Gangwon-do, Korea. The purpose is to develop a monitoring system of open-pit mines that enables any person to monitor the topographic and environmental changes caused by mine operations and to develop and restore the area’s ecology. Open-pit mines were classified into active or inactive mines and monitoring items and methodologies were established for each type of mine. Cesium which is a WebGL-based open-source platform was chosen as it supports dynamic data visualization and hardware-accelerated graphics related to elapsed time which is the essential factor in the monitoring. The open-pit mine monitoring system was developed based on the geospatial database which contains information required for mine monitoring as time elapses, and by developing the open-source-based system software. The geospatial information database for monitoring consists of digital imagery and terrain data and also includes vector data and the restoration plan datas. The basic geospatial information used in the monitoring includes high resolution ortho image(GSD 0.5 m or above) for all areas of the mines. This is acquired by periodically using an airborne laser scanning system and a LiDAR DEM (grid size 1m × 1 m). In addition, geospatial information data were acquired by using an UAV and terrestrial LiDAR for small-scale areas; these tools are frequently used for rapid and irregular data acquisition. The geospatial information acquired for the monitoring of the open-pit mines represents various spatial resolutions and different terrain data. The database was constructed by converging this geospatial information with the Cesium-based geospatial information open platform of the ESRI World Imagery map and with SDK World Terrain meshes. The problems that resulted from the process of fusing aerial imagery and terrain data were solved in the Cesium-based open source environment. The prototype menu for the monitoring system was designed according to the monitoring item which was determined by the type of mine. The scene of the mine and changes in terrain were controlled and analyzed using the raster function of PostGIS according to the elapsed time. Using the GeoServer, the aerial imagery, terrain and restoration information for each period were serviced using the web standard interface, and the monitoring system was completed by visualizing these elements in Cesium in 3D format according to the elapsed time. This study has established a monitoring methodology for open-pit mines according to the type of mine and proposes a method for upgrading the imagery and terrain data required for monitoring. The study also showed the possibility of developing a Web3D-based open-pit mine monitoring system that is applicable to a wide range of mashup service developments

SEEING THE UNSEEN: DELIVERING INTEGRATED UNDERGROUND UTILITY DATA IN THE UK

In earlier work we proposed a framework to integrate heterogeneous geospatial utility data in the UK. This paper provides an update on the techniques used to resolve semantic and schematic heterogeneities in the UK utility domain. Approaches for data delivery are discussed, including descriptions of three pilot projects and domain specific visualization issues are considered. A number of practical considerations are discussed that will impact on how any implementation architecture is derived from the integration framework. Considerations of stability, security, currency, operational impact and response time can reveal a number of conflicting constraints. The impacts of these constraints are discussed in respect of either a virtual or materialised delivery system. 1

Buenas prácticas para el desarrollo de mapas de ruido dinámicos en entornos Web GIS

Geographic Information Systems(GIS) in web environments (Web GIS) sets up anew way of working geodata based on internetconnections. Noise maps are tools which allowsdisplay of environmental noise levels in a specificarea, enabling spatial analysis to support decision inaspects related to noise control. Currently, differentGIS communities focus their efforts on findingmethods for development of GIS projects aimedto obtain spatial data in a static way, requiringprofessional staff to get spatial data. Also, thesemethods lack strategies of getting requirements,acquisition, manipulation and maintenance of spatialdata dynamically. Therefore, this article proposes amethod for development of Web GIS applicationswhich integrates phases in Web GIS developmentand considers best practices in development cycleof agile methodologies and GIS projects, seeking toimprove the process of acquisition of geodata fromcollaborative platforms. In addition, the validationof proposal is carried out through a case study ofthe generation of dynamic noise maps for the cityof Medellín. This proposal improves the process ofacquisition of dynamic spatial data and developmentcycle of Web GIS application, incorporating the bestpractices required for the development of Web GIS.Los Sistemas de Información Geográfica (SIG) en entornos web (Web GIS) establecen una nueva forma de trabajar los geodatos basados en conexiones a internet. Los mapas de ruido son herramientas que permiten desplegar los niveles de ruido ambiental en una zona determinada, lo que posibilita el análisis espacial para apoyar la toma de decisiones en aspectos relacionados con el control del ruido. En la actualidad diferentes comunidades de SIG enfocan sus esfuerzos en identificar métodos para desarrollar proyectos SIG orientados a obtener geodatos de manera estática, y necesitan personal especializado para adquirir los geodatos. Además, estos métodos carecen de estrategias de educción, adquisición, manipulación y mantenimiento de los geodatos de forma dinámica. Por lo anterior, en este artículo se propone un método para desarrollar aplicaciones Web GIS, que integra las fases en el desarrollo Web GIS y considera las buenas prácticas en el ciclo de desarrollo de metodologías ágiles y de proyectos SIG, con el fin de mejorar el proceso de adquisición de geodatos desde plataformas colaborativas. La validación de la propuesta se realiza mediante un caso de estudio de generación de mapas de ruido dinámicos para la ciudad de Medellín. Esta propuesta mejora el proceso de adquisición de geodatos dinámicos y el ciclo de desarrollo de una aplicación Web GIS, incorporando las buenas prácticas requeridas para el desarrollo del Web GIS
