Vector Data Structure Advantage


1. Good representation of phenomenological data structure.
2. Good compact data structure.
3. Topology can be completely described with network linkages.
4. Accurate graphics.
5. Retrieval, updating and generalization of graphics and attributes are possible.


1. Complex data structures.
2. Combination of several vector polygon maps or polygon and raster maps through overlay creates difficulties.
3. Simulation is difficult because each unit has a different topological form.
4. Display and plotting can be expensive, particularly foe high quality, color and crosshatching.
5. Technology is expensive, particularly for the more sophisticated software and hardware.
6. Spatial analysis and filtering within polygons are impossible.
