Message Exchange For Web Services-Based Mapping Services

The Open Geospatial Consortium (OGC) [1] defines a number of standards, both for data models and for online services, that has been widely adopted in the Geographical Information System (GIS) community. This has lead to a number of software development efforts, online data archives, and application communities. The emergence of Web Service technique overcomes the … Read more

Developing GIS Visualization Web Services For Geophysical Applications

The Open Geospatial Consortium (OGC) defines a number of standards (both for data models and for online services) that have been widely adopted in the Geographical Information System (GIS) community. In this paper we will describe our group’s efforts to implement GIS services according to OGC standard specifications in accordance with the Web Services approach. … Read more

Building Sensor Filter Grids: Information Architecture for the Data Deluge

We discuss a general architectural approach to knowledge and information management and delivery in distributed systems. Our approach is based on the recognition that time-stamped, streaming information message units form the core of seemingly disparate systems that range from online sensors and scientific instruments to Web information retrieval. Globally distributable Grid services manage these information … Read more

Ant based interactive tools for workflow management

The Apache Ant presents certain characteristics that seem to make it suitable as a workflow language and engine. Features such as native dependency structured build targets make it easy to write declarative dependency-based workflows. We propose a framework enabling Ant build files (and its specifications) to be used as workflow scripts. Features like being semi … Read more
