raster

The horizontal lines (scan lines) displayed on a TV or computer monitor. This is the origin of the term "raster graphics," which is the major category that all bitmapped images and video frames fall into (GIF, JPEG, MPEG, etc.). See raster scan, raster display, analog video and bitmapped graphics.

All the raster had different cell values, so for suitability analysis it was necessary to standardize all the data to a common scale by ranging between the scale of 1 to 5, where a score of 1 indicated least suitable and a score of 5 indicated most suitable, as shown in Table 1.
High resolution image datasets are geographically interfaced and are often stored in the disk file system in the format of raster, while the dataset's large-scale volume places restrictions on the efficient organizing and indexing of itself in traditional database, which becomes the bottle-neck of efficient image visualization.
