Raster data consists of pixels. Each pixel, has an associated value. A grid of cells, represents this data. In other words, it is, a matrix of cells organized into rows and, columns. Each cell has a value that, represents information. Chemical, concentrations and elevation surface are, , some examples of raster data., , , , , , , , , raster/, pixel, , lijnstuk (geel), , gedragen door, vertices (roze), , Raster data is simple. They are easier to, simulate as all the cells are of the same, size and same shape. On the other hand,, raster data can cause information loss. It, can also be difficult to establish network, linkages. Moreover, if there is no special, hardware or algorithms, the projection, , transformations can be time-consuming.
