Discrete Spatial variables: Basic concepts: Spatial Features

1.1.3. 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 object can be defined as a set of contiguous cells, which is called as region.

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 phenomenons of spatial objects are more meaningfully presented in image mode.

Spatial features (reminder)

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