Geoinformatics and Data Modelling
Theme Overview:
What is Geoinformatics?
Informatics is the science of information, the practice of information processing, and the analysis of information system development. Geoinformatics therefore refers to the application of this science to the geospatial realm, with its particular objects, goals and challenges. It combines geospatial analysis and modelling, the development of geospatial databases, information systems design, human-computer interaction and both wired and wireless networking technologies. It is concerned with the structure, algorithms, behaviour, and interactions of any system with a geospatial aspect, examining how information is stored, processed, and accessed within it.
Geoinformatics is not merely the application of technology to geographical systems and the geosciences - it is far more foundational than that. Geoinformatics has to develop its own conceptual, theoretical and even philosophical foundations of how we interpret the world around us, and its geographical attributes. How best to model geospatial data is the fundamental component of geoinformatics.
Science First, then Technology
Since the advent of computers, individuals and organizations increasingly want to process geospatial information digitally - however CGS prioritizes scienctific analysis first, with the application of technology only following in its wake. It is only through application of scientific method the best solution to a problem domain can be isolated: whether Relational Databases, Object Oriented Models, XML or Semantic Web.
Irregular and Semi-Structured Data
Geospatial Science is a vibrant domain due to the irregularity of its data. The world as we interpret it simply will not fit into neatly packaged schemas or universal ontologies. And yet no contemporary theory of data seems up to the task. CGS pioneers research in geospatial models, attempting to address this gap. Resulting theories and technology have been integrated into the CGS led Reality Markup Platform (RAMP) initiative.
