Innovative Web-Based Geographic Information System for Municipal Areas and Coastal Zone Security and Threat Monitoring Using EO Satellite Data

The paper presents a novel design of a web-based Safe City & Coastal Zone GIS (SCCZ-GIS). The system integrates data acquired from different remote sensing and geospatial data sources for the purpose monitoring the security of the coastal zone, its inhabitants and critical infrastructure. The system utilizes several innovative technologies and solutions and is capable of direct co-operation with different remote sensing data sources and services, including satellite ground station and ESA Service Support Environment. The system runs in operational mode, and the results of the analysis are ready in quasi real time, that is, immediately after receiving a new scene of satellite imagery. The system may be accessed by authorized users either through a web-based client or mobile device application. The paper describes the architecture of the system and presents several case studies where the software is applied to processing of earth observation satellite and spatial analysis of coastal zone infrastructure.

Real-time Web-based GIS for Analysis, Visualization and Integration of Marine Environment Data

Visualization and integration of the marine spatial data collected by various marine sensors and sources is an important factor in the context of marine environment sensing and monitoring. Several approaches and techniques of measurements are available to achieve this purpose including direct sampling, airborne and satellite imagery, and underwater acoustics. The paper briefly describes the state-of-the art marine GIS system developed in the Department of Geoinformatics of Gdansk University of Technology, Poland. The proposed system is able to integrate many different types of marine data, especially those acquired by various acoustic sensors like multibeam sonar (MBSS), echosounder and side scan sonars (SSS), and other external sensors such as satellite data receiver, radar, or automated identification of ships (AIS) data analyzer. Instantaneous 2D and 3D visualization is provided by the two components of the system: GeoServer web-based module and a standalone application basing on ESRI ArcGIS Engine solutions.

Automatic Detection and Monitoring of Cyanobacterial Blooms in the Context of the Marine Cadastre

In the wake of the European and global spatial data infrastructures (SDI) it is important to build information systems which use and serve thematic data in compliance with the INSPIRE Directive. In the context of hydrographic data, the Directive requires EU member states to collect and share information on maritime areas divided into regions and sub-regions, as well as coastal zone management areas. These data are part of recently developed marine cadastres. According to the INSPIRE Directive the marine cadastres should be supplemented with information on the physical condition of the seas as well as on the specific natural characteristics and phenomena occurring in the seas. The latter can include dynamic information on marine pollution such as cyanobacterial blooms. The paper presents the concept of dynamic satellite-based cyanobacteria bloom detection for the purpose of its analysis in the context of marine cadastre.

Towards solving heterogeneous fleet vehicle routing problem with time windows and additional constraints: Real use case study

In advanced logistic systems, there is a need for a comprehensive optimization of the transport of goods, which would reduce costs. During past decades, several theoretical and practical approaches to solve vehicle routing problems (VRP) were proposed. The problem of optimal fleet management is often transformed to discrete optimization problem that relies on determining the most economical transport routes for a number of vehicles in order to deliver (or pick up) certain amount of goods to geographically distributed set of customers. However, real life problems generally differ from the classical cases because they impose additional constraints to be satisfied. Therefore, research related to developing dedicated theoretical and technological solutions fitted to particular real life use case are very important. In the paper, the particular variant of the VRP problem which is an exemplification of the real-life business case is presented. Authors of the paper proposed an architecture of modular system and an algorithm designed to solve the real-world variant of the VRP which is important from the business perspective.

Method to extend operationability of web-GIS based marine services using SSE platform

Abstract Earth Observation (EO) products are widely used by geospatial society. Over the last years a number of new applications of satellite imagery were proposed. This led to an increased interest in EO products, not only from researchers but also from companies and individuals. The authors constitute the essential part of the team that created the marine, web-GIS system - SafeCity GIS - for dissemination of data obtained from a 1.5 metre HRPT-MetOp satellite ground receiving station. To increase the operationability of the system the authors successfully attempted to broaden the offered functionality by integration with Service Support Environment (SSE). Due to this, EO products for the Pomeranian Region are served as web-services; amongst them there are True Color imagery, meteorological, algae monitoring and fire-detection services. The authors present the created solution for web service support for GIS system based on Service Support Environment and discuss its advantages and disadvantages.

Using EO satellite data in Safe City and Coastal Zone web-GIS

The paper presents a novel design of a web-based Safe City & Coastal Zone GIS (SCCZ-GIS) which integrates data acquired from different remote sensing and geospatial data sources for monitoring the security of the coastal zone, its inhabitants and Critical Infrastructure. The system utilizes several innovative technologies and directly co-operates with different remote sensing data sources and services, like a satellite ground station or ESA Service Support Environment. The results of analysis are ready in quasi real time, e.g., immediately after receiving the new scene of satellite imagery. Also, the system is accessible for authorized users by a client application oriented either to a browser-based personal computer platform, or to mobile devices.
