Opis:: Geographic Information Systems (GIS) are an excellent tool for integrating various types of spatial information. They provide functionalities which allow for quick analysis and correlation of various types of data in a geographical context. The paper presents a Webbased GIS dedicated for integration and analysis of marine data from satellite imagery. The system operates with the use of automatic image processing procedures, which allow for detection of several different characteristics such as surface temperature or the existence and location of blooming algae. The system correlates the processing results with information from other sources, including vessel movement acquired from the Automatic Identification System, as well as results of oil spill simulation. The paper presents the architecture of the system as well as sample layers produced by the employed algorithms.

Opis:: Presenting geographic data in a web environment has been a long standing problem. For many years the low performance of web browsers has limited the visualization of spatial data to only two dimensions. More recently, the introduction of open standards for 3D acceleration of web applications sparked the emergence of new methods of presenting threedimensional data in a web browser without using third-party extensions. However, these solutions are relatively young and not yet fit for use in a production environment. This work presents a method of three-dimensional representation of geospatial data in the context of two-dimensional map. The presented system uses the well-proven OpenLayers library as well as HTML5 and WebGL technologies to display three-dimensional geospatial data in the web without the need for additional web browser plug-ins. The presented application may thus constitute a viable solution until the more robust solutions mature.

Opis:: The continuous detailed surveys of the various water bodies, over time, produce a large and ever-increasing volume and density of underwater sounding data. Threedimensional data, such as that obtained by multibeam sonar systems, are quite complex to manage; and thus, their growing numbers increase the pressure on the development of new solutions dedicated to processing them. This paper presents a concept system for a web-based dissemination of multibeam data in a geographic context. In order to maintain an easily accessible user interface, processing and distribution of such datasets in the web environment requires the data to be converted into a file format which is fit for processing via a web browser. Because of this, the presented system uses the emerging 3D Tiles open standard for serving multibeam point clouds alongside reconstructed three-dimensional models of shipwrecks, to remote users in a web environment, by means of Cesium, an open source WebGIS library for 3D visualization of geospatial data.
