Positional and Rational Procedures - SS1 Geography Lesson Note

Positional Procedures: These are rules and techniques for accurately representing the locations of geographical features on maps or in digital form. For example, ensuring that coordinates align correctly on a map.

These procedures ensure that the locations of features, like roads, buildings, or natural landmarks, are correct on a map. They use coordinates, scales, and measurements to make sure everything fits together accurately.

 

Rational Procedures: These involve logical and mathematical methods for analyzing and interpreting data. This includes calculations, modeling, and decision-making processes within GIS.

These procedures help make sense of the data. They include calculations, modeling, and decision-making processes. For example, they can be used to find the shortest route between two points on a map or to predict environmental changes.
