| Vector Data Model | Raster Data Model |
|---|---|
1. It is a simple data structure. |
1. It is more complex data structure. |
2. Suitable for Recording discrete features with definable boundaries. |
2.Representing continuous spatial features. |
3. Attaching both textual and numerical attributes to spatial features, and managing and analyzing these attributes and through them the features themselves. |
3. Containing images (aerial, satellite) |
4. Editing, updating, and management of the spatial features. |
4. Analyzing spatial relations between features (cost-path, density, interspersion, edge contact, etc.). |
5. Vector data is comprised of vertices and paths. |
5. Raster data is made up of a grid of pixels. |
6. Overlay operations areeasily and efficiently implemented. |
6. Overlay operations are more difficult to
Implement. |
