WebGIS.

Spatial GIS web tools and resources

The power of WebGIS in promoting robust and integrated geospatial solutions

This is the main page of the GeoCAS web mapping portal. The state-of-the-art in Geographic Information Science and applications is the integration of WebGIS into the core scientific spatial and geospatial analysis workflows and applications. With the unprecedented increase in global network and communication capacities and capabilities, along came the need for providing scientifically sound and robust tools and applications available for scientists, students, professionals, institutions, organizations and communities at large. Online WebGIS platforms for "big data" integration and analytics represent the future of geospatial computing and spatial sciences.

Within this conceptual framework, GeoCAS produces and maintains a Web Mapping portal closely integrated to all our physical Data portal infrastructure.
