INSPECTORMAP: A Spatial Data Infrastructure Applied to the Maintenance of Solar Plants Using Free Satellite Imagery

Photovoltaic solar plants are one of the main facilities away from urban centers for the generation of clean energy. Since its appropriate maintenance ensures its suitable operation, optimizing their maintenance tasks in a preventive way is key. This article presents a spatial data infrastructure called INSPECTORMAP that, based on the analysis of free satellite images within the optical spectrum, can detect unusual vegetation and bodies of water in the vicinity of photovoltaic plants that can affect their correct operation. Thanks to the implementation of a monitoring and alert system, it is possible to know and map the status of the photovoltaic plant in terms of unusual coverages appearing, both natural and artificial, at any moment. Thus, maintenance workers would travel to the solar plant to carry out their maintenance tasks in this regard only when the system detects a risk.

Abstract The cadastral data, including land parcels, are the basic reference data for presenting various objects collected in spatial databases. Easy access to up-to-date records is a very important matter for the individuals and institutions using spatial data infrastructure. The primary objective of the study was to check the current accessibility of cadastral data as well as to verify how current and complete they are. The author started researching this topic in 2007, i.e. from the moment the Team for National Spatial Data Infrastructure developed documentation concerning the standard of publishing cadastral data with the use of the WMS. Since ten years, the author was monitoring the status of cadastral data publishing in various districts as well as participated in data publishing in many districts. In 2017, when only half of the districts published WMS services from cadastral data, the questions arise: why is it so and how to change this unfavourable status? As a result of the tests performed, it was found that the status of publishing cadastral data is still far from perfect. The quality of the offered web services varies and, unfortunately, many services offer poor performance; moreover, there are plenty services that do not operate at all.

Abstract. Urban infrastructure deals with various objects, such as multi-floor buildings, underground utilities, and other typical two-dimensional (2D) geographic information system (GIS) objects. Currently, Oman and Qatar authorities attempt to manage and handle all these spatial objects and features via spatial data infrastructure (SDI). Qatar has a long tradition of applying SDI, while Oman has made rapid progress in building SDI according to the current practices in this field. Governments in both countries work toward smart cities and e-government to meet the fourth industrial revolution requirements. Current literature, indicate that SDI could be considered a major building block for such smart initiatives in the near future. This paper describes the status and challenges of developing SDI (including 3D SDI) for Oman and Qatar. We anticipated these 2D and 3D SDI initiatives would eventually provide future direction for the smart city and e-government. The current status and challenges form major discussions of this paper. It also discusses 3D SDI development. This paper ends by describing a framework for implementing the 3D SDI. The outcomes could significantly improve the awareness for developing 3D SDI in Oman and Qatar.
