We propose a service oriented distributed system framework for animating big spatiotemporal vector datasets. The aim is exploiting the patterns in spatial data dynamically changing over time. Animation consists of succes- sively played and temporally related still map images. Each map image in the animation is a satellite map enriched with (or plotted over) spatiotemporal … Read more
Geographic and non-geographic attributes of spatial datasets enable them to be integrated and analyzed in many GIS applications through visualization and analysis tools. The coordinate values of spatial datasets are defined by SRS (Spatial Referencing System) and projection together, and converted to the screen (view) coordinates through coordinate transformations. In this study, we approach this … Read more

The Open Geospatial Consortium (OGC) 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. We survey these in the first part of this … Read more
We describe our continuing work on implementing Open GIS Consortium (OGC) compatible Grid Services for the International Solid Earth Research Virtual Observatory. Our initial efforts focused on collecting Earthquake and GPS data from various sources, converting them to GML and enabling query capabilities using pure Web Services approach. We have extended this work by creating … Read more
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
