Overview
Geographic Information Science (GIS) through raster analysis, geographic visualisation and big spatial data. Surface and hydrology analysis, visual communication in three dimensions and time, and GIS algorithms and customisation emphasised.
This is an intermediate level Geographic Information Science (GIScience) paper, reflecting the increasingly prominent role of Geographic Information System (GIS) technologies in the world at large. Evidence for this comes from the ubiquity of GIS apps such as Google Earth and Google Maps, associated crowdsourcing resources for various themes (e.g. OpenStreetMap) and the elevated profile of GIS within professions and disciplines (e.g. nationally, the recent change from ‘Surveying’ to ‘Surveying and Spatial’).
The paper will explore large volume and complex spatial datasets (Digital Elevation Models, including 3D point cloud data), whilst extending spatial analysis into raster analysis. The surface modelling aspect of that combines with 3D space and time visualisation content to form a body of content that builds on the foundations of GIS analysis and visualisation through a strong focus on continuous natural phenomena.
Other topics include surface analysis methods, hydrological techniques and visibility modelling. The geographic visualisation module will extend from mapmaking into more complex, flexible and realistic communication technologies such as 3D GIS, Virtaul Reality (VR) and tangible Augmented Reality (AR). These are underpinned by spatial data handling topics such as point to surface conversion and uncertainty management. The paper ends with a short capstone project that applies and integrates the major topics covered, also a research essay on a selected spatial analysis and visualisation topic.
This paper and the introductory GIS paper together form a comprehensive package, covering the essential GIS aspects of data, analysis and visualisation for surveyors, geographers, geologists, life scientists and health scientists, amongst others, who will need GIS knowledge and skills going forward.

Through successful completion of this paper, students will be able to:
- Extend spatial analysis knowledge and skills by applying simple raster analysis techniques such as reclass, map algebra and filtering.
- Explain the basic theory of and apply surface, hydrological and visibility analysis methods using Digital Elevation Models (DEMs).
- Apply conversion methods from vector to raster, including interpolation.
- Describe 3D and space-time data structures.
- Explain the basic theory of and apply 3D modelling in various contexts using GIS, extending into more complex, flexible and realistic 3D tools, Virtual Reality (VR) and tangible Augmented Reality (AR).
- Translate basic visualisation techniques to other contexts such as data of dynamic phenomena, uncertain data and analysis planning.
- Apply this knowledge practically through a capstone project that unifies data handling and uncertainty, analysis and visualisation skills and knowledge.
- Demonstrate mastery through the planning, research and writing of an essay on a selected spatial analysis and visualisation topic.
