Learning Outcomes

Upon successful completion of this subject, students should:
Understand the mathematical concepts required for the development of GIS and CAD related algorithms;
Have gained a good understand of applications of computational geometry concepts to GIS and modelling;
Be able to analyse, modify and design various GIS algorithms that employ geometrical concepts.


The subject will cover the following topics:
Concept of space and geographical data; Introduction to geometrical concepts used in GIS and modelling; Curves (including interpolation and splines concepts widely used in GIS); Relational properties: distance between two points; distance between a point and a curve; distance between two curves; Intersections: line, plane and curve intersections; Coordinate systems and map projections for GIS - Terrestial systems - Plane systems - Projections (transformations) - Choice of a suitable projection; Transformations used in GIS - Translation, rotation, scaling - Homogeneous transformations - Nonlinear transformations; Fundamental graphical procedures used in GIS - Vector techniques - Raster techniques; Projections on computer graphics - The Display Environment - Projections - Scene transformations - Hidden surfaces; Computer systems and low and high level data structures for GIS - Classification of systems - Software development strategy - Spatial Data models and structures - Three dimensional GIS.
