Neither raster nor vector is perfectly suited to model all real world phenomena. Identify three strengths and two weaknesses for raster data and for vector data.

Vector advantages :-

1. Without generalisation, data may be represented at its native format and shape.

2. Because most information is in vector form , e.g. hard copy charts, no data translation is necessary.

3.It maintains exact geographic position of the results.

Vector disadvantages :-

1. You need to specifically store the position of each vertex.

2. Spatial interpretation and filtration is not feasible inside polygons

Raster advantages :-

1. Normally, data analysis is simple to programme and fast to execute due to the simplicity of the digital storage methodology.

2. The underlying design of the raster maps is best suited for statistical simulation and quantitative analysis, e.g. one attribute charts.

3. Discrete data, such as tree ranges, is as well accommodated as continuous data , e.g. altitude data, which enables the convergence of the two data forms.

Raster disadvantages :-

1.The size of the cell specifies the resolution the data are interpreted at.

2. Based on the cell intensity it is extremely difficult to accurately reflect linear features. Therefore network links are hard to create.
