Web-Based GIS as a Tool for Supporting Marine Research

Abstract

Collecting marine data during hydroacoustic research surveys is a complex task, which not only consists of measurements but also analysis, validation, and interpretation of information acquired by various sensors. Automatic integration, visualization, and processing of collected data allow for a more precise investigation of the researched phenomena. The paper presents a dedicated Web-based system for fusion and dissemination of data from satellite imagery, hydrological measurements using CTD probes, acoustic surveys by multibeam systems, side-scan sonars and singlebeam echosounders, as well as live radar feed and oil spill spread models. The system has been designed as a tool for supporting research using the aforementioned techniques.

Maritime Laser Scanning as the Source for Spatial Data

“…The results and the obtained models can be a source for supplying marine charts systems (also within the frames of sailing directions) with the information based on visualizations and 3D presentations. Experiments carried out in recent years by various authors suggest that the use of a 3D maps improves the quality of navigation [5,6,18,21,22], and may also help to improve the safety of vessels and to protect water regions against danger [7,10,16,17]. Ease of obtaining spatial data and technological capabilities of scanning allow to assess the presented solution as the technology that in the short time will become the standard method of obtaining information about the coast of seawaters and inland waters.…”

A novel method for archiving multibeam sonar data with emphasis on efficient record size reduction and storage

“…Application of online analysis algorithms enables extraction of water-column data such as pelagic fish schools on-the-fly as well as their visualization in 3D context alongside digital terrain data such as bathymetry (Kulawiak 2010). Fig.…”

Information About Dynamics of the Sea Surface as a Means to Improve Safety of the Unmanned Vessel at Sea

“…We may see its influence on the behavior of small boats, research vessels and unmanned surface vessels doing bathymetric tasks, laser scanning of the cliffs or infrastructure of harbor facilities [7,9,11,14,17,18]. The mathematical description of that phenomenon gives us the possibility to improve the quality of the data [22] dedicated to the spatial information systems and electronical navigational charts [16,20] integrating information about shore infrastructure, shape of the sea bottom and waterways in the vicinity of the ports [12,13,15,21].…”
