Question

Quizplus · Accepted Answer

Overlay analysis is the most appropriate function for analysing the spatial associations between rainfall, elevation, and vegetation as it allows for the combination of multiple layers to create new output layers. This can be used to identify areas where specific combinations of variables exist, such as areas with high rainfall and high vegetation cover at high elevations. Query and buffering functions are more suitable for selecting or isolating specific features within a layer, while surface analysis functions are primarily used for modelling terrain or elevation data.
