Geoinformatics encompasses a collection of special techniques, technologies, and tools for the acquisition, processing, management, analysis, and presentation of geospatial data. Geoinformatics is based on a range of synergetic activities including geospatial modeling, geospatial analysis, geospatial databases, geospatial technologies, information systems, systems design, spatial cognition, human-computer interaction, mobile computing, wired and wireless network technologies. Today, numerous applications are benefiting from geoinformatics techniques, technologies, and tools and with recent advances in geoinformatics and related technologies, such as Web services and grid computing, new geoprocessing paradigms and applications are expected to emerge.
