Spatial Features

The spatial objects can be represented in object (vector) mode or image (raster) mode. In object mode, individual spatial objects can be defined as point or line or polygon. In image mode, individual spatial objects can be defined as a set of contiguous cells, which are known as regions.

Although a spatial object and phenomenon can be defined in object mode and image mode. Discrete spatial objects can be more accurately present in object mode and continuous phenomena of spatial objects are more meaningfully presented in image mode.

The following presentation will focus on structures of lessons that illustrate concepts, techniques and methodologies on how to represent features in object mode or image mode based on discrete sample data collection of geographic features and their phenomena.
