Solution
|
Raster Data Models |
Vector Data Models |
|
1. Raster data represents a graphic features as a pattern of grids of squares. |
1. Vector data represents the object as a set of lines drawn between specific points. |
|
2. A Raster file would represent the image by sub-dividing the paper into a matrix of small rectangles similar to a sheet of graph paper called cells. |
2. A vector representation of the same diagonal line would record the position of the line by simple recording the coordinates of its starting and ending points. |
