Analysis of Geographic Data
Geographic Analysis
Analysis of problems with some Geographic Aspects.
- Alternatives are geographic locations or areas.
- Decisions would affect locations or areas.
- Geographic relationships are important in decision-making or modelling.
Some examples of its application:
- Nearest Neighbour.
- Network distances.
- Planar distances.
Spatial Analysis - An Application

Where should we build a road from a point A to point B?
How do we minimise the impacts of building this road?
Relationship of Modelling to Analysis
- Decision Models search through potential alternatives to arrive at a recommendation.
- Decision support models process raw data into forms that are directly relevant to decision making.
- Data characterisation models are used to develop a better understanding of a system to help characterise a problem or potential solutions.
