As you have learnt in the spatial modelling lesson, spatial objects can be described as point, line and polygon (areal) features. Moreover, the spatial objects can be represented in object mode and/or image (raster) mode. In this unit, you will learn how to describe the geometric properties of spatial objects in image mode and object mode.
At the end of the unit, you should be able to describe geometric properties of point features, linear features and polygon features in image mode or object mode especially for your spatial analysis projects.
