Challenges on geo spatial visual analytics eurographics
The document discusses the development of an advanced 3D geobrowser client-server solution. Some key points: - The client is a 3D geobrowser developed using Java and built on World Wind APIs that allows users to visualize and interact with geospatial data through a web interface. - The server side utilizes Java EE and provides interoperable access to data through OGC standards like WMS, WFS, WPS and CSW. It also enables high performance through server clustering. - The system allows interactive analysis and visualization of geospatial data in 3D for applications like emergency response and decision support. Users can access maps, features and sensors through the thin client interface.

- 29. In orderto support administrators and crisis managers during normal monitoring conditions as well as in case of exceptional events it is essential to develop tools for modelling and simulating different operative conditions within an environmental scenario. In fact planning on how to handle acute crises is of prime importance for adequate response. The impact of proper modelling and real-time simulation tools is very high both in social and economical terms as proper cross border crisis management can potentially save lives and bring to huge costs saving. For this reason it is necessary to develop an infrastructure capable to support access and management of data coming from real world sensors. The simulation framework should be used to define hybrid simulation strategies capable to allow real-time response and progressive refinement of simulation results over time. This is essential to provide users with different sets of counteraction alternatives, when facing simulations of exceptional events. This way the resulting infrastructure can be used in control loop as a decision support system during crisis events.

- 57. Service-Oriented Architecture(SOA) solution consists in three main logical components: consumers SOA infrastructure applications service support services producers
- 58. The logicalcomponent ”Consumers” is composed by entities that makes use of offered services (e.g. desktops, laptops and mobile interfaces or even web services that can call a service) communicates with the SOA infrastructure through a transport protocol (e.g. HTTP or ..).
- 59. SOA infrastructurelayer can be divided into three subcomponents: ”Applications”, which provides a graphic interface for consumers to visualize and perform tasks ”Service Support”, which provides the background support functions for SOA (e.g. CSW for directory and ESB Architecture for communication) ”Service” which is composed by entities that performs a specific task when invoked
