“…The preliminary underground survey conducted for the HYDROGIS project shows positive results in using ground penetrated radar to identify the underground pipe network in the Municipality of Paphos 11,12,13 . GPR scanning is a useful tool for modeling the water supply network, design and operation, with the goal of minimizing water loss.…”

The ΗydroGΘS Lab project http //cyprusremotesensing.com/hydrogis/ aims to satisfy the dire need for authorities to solve the extremely serious problem of water supply as a result of continued water shortage. The chronic problems of water losses in the water supply network pipes, the uncontrolled and non-optimum operation of pumping stations, the incorrect design of the networks because of various interventions such as town planning and erroneous mapping of existing networks, are some of the most important problems which need to be resolved in order to optimize the performance of the networks and, consequently, save water and energy. The innovative aspect of the Project is that state-of-the-art technologies are combined for the mapping of water networks through the Global Positioning System GPS , Radar Scanners and Satellite Remote Sensing SRS . The data is entered into a Geographic Θnformation System GΘS , with the aim of developing a digital imprint and the mapping of the network. The study of an existing selected water supply network and the collection of the necessary information by the Βyprus University of Technology and the Water Development for the network and its systems will lead to an imaging of water pipes and their design using a radar scanner and special software and GΘS. Satellite images, which have been transformed into the local reference system using specialized software, will be coupled with the digital imaging of the existing maps. This information will then be organized in such a way allowing the development of maps and their analysis at different levels e.g. water supply network, buildings, water supply elements, geographic information, features of the network s systems, etc. .

“…Although GPR has many supporters, its handling is not trivial, even for experts (Annan, 2009;Jol 2008;Rahman and Zayed, 2016). First, it is noticeable that there is a lack of specialized tools to help the data acquisition pipeline, from getting contextual data prepared before going in the field to the visualization of GPR data within the project's context (Dallaire and Garneau, 2008;Li et al, 2015;Themistocleousa, et al, 2015;Talmaki et al, 2013;Tischeler 2003;Zheng et al, 2004). These steps require an integration of resources which varies in format, data organisation, and semantic details.…”

ABSTRACT:For the planning and sustainable development of large cities, it is critical to accurately locate and map, in 3D, existing underground utility networks (UUN) such as pipelines, cables, ducts, and channels. An emerging non-invasive instrument for collecting underground data such as UUN is the ground-penetrating radar (GPR). Although its capabilities, handling GPR and extracting relevant information from its data are not trivial tasks. For instance, both GPR and its complimentary software stack provide very few capabilities to co-visualize GPR collected data and other sources of spatial data such as orthophotography, DEM or road maps. Furthermore, the GPR interface lacks functionalities for adding annotation, editing geometric objects or querying attributes. A new approach to support GPR survey is proposed in this paper. This approach is based on the integration of multiple sources of geospatial datasets and the use of a Web-GIS system and relevant functionalities adapted to interoperable GPR data acquisition. The Web-GIS is developed as an improved module in an existing platform called GVX. The GVX-GPR module provides an interactive visualization of multiple layers of structured spatial data, including GPR profiles. This module offers new features when compared to traditional GPR surveys such as geo-annotated points of interest for identifying spatial clues in the GPR profiles, integration of city contextual data, high definition drone and satellite pictures, as-built, and more. The paper explains the engineering approach used to design and develop the Web GIS and tests for this survey approach, mapping and recording UUN as part of 3D city model.

“…Still, all these efforts were very specific and did not systematically integrate all available information. Methodologies integrating several techniques, such as GIS, earth observation and ground-based methods to study and analyze several physical factors, have been widely described and applied in the literature [8,11,13,15,19,20,23].…”

An integrated GIS-based method for wind-power estimation: application to western Cyprus

et al. 2014

This study presents an integrated method for the estimation and analysis of potential wind-energy resources inCyprus, which is applied at selected sites on the western side of the island. Firstly, a statistical analysis of wind speed and direction data was conducted at six meteorological stations in western Cyprus, establishing daily, monthly and annual variations of wind speed. Also examined were the Weibull distributions of the wind at each site. These wind statistics serve as the basis for estimating corrected statistical distributions over the extended study areas, which were calculated using the Wind Atlas Analysis and Application Program (WAsP) that modifies wind flow estimates based on local topographic effects. As a result, a geographic and wind-resource database was formulated around each station. Aggregation of this data using statistical weighting methods allows the extrapolation of observed results and the visualization for selected hours of the day over the western part of Cyprus. The results indicate the strong influence of the sea-breeze on the island's wind potential, and identify a number of areas of higher wind-energy potential suitable for wind-resource exploitation. It is hoped that both the methodology applied and results obtained can be further used by potential investors and wind-energy developers.
