Advantages of vector data models over raster model?

• Data can be represented at its original resolution and form without generalization.

• Graphic output is usually more aesthetically pleasing (traditional cartographic representation);

• Since most data, e.g. hard copy maps, is in vector form no data conversion is required.

• Accurate geographic location of data is maintained.

• Allows for efficient encoding of topology, and as a result more efficient operations that require topological information, e.g. proximity, network analysis.

• Compact data structure; requires less space to store data
