A raster navigational chart is an accurate digital image comprised of pixels, displayed on an electronic screen. Each pixel has a unique color or it has no color. The pattern of the colored and the empty pixels gives shape to the individual features of the chart. Ideal for both planning and navigation, they can help simplify operational tasks and improve situational awareness.
Using the formatted images in electronic display systems called Raster Chart Display Systems (RCDS), mariners receive accurate real-time vessel positions. Hence they are also known as marine navigation charts.
Benefits furnished by raster charts have been mentioned below:
1. The geographical loci of each cell is implied by its position in the cell matrix. No geographic coordinates are stored, other than an origin point such as bottom left corner.
2. Because of the nature of the data storage method, analysis is normally easy to program and quick to perform.
3. The inherent nature of raster maps, for example one attribute maps, is ideally suited for mathematical modeling and quantitative analysis.
4. Discrete data, like forestry stands, is housed equally well as continuous data, say for example elevation data and facilitates the integration of the two data kinds.
5. Grid cell systems are thoroughly compatible with raster based output devices. Such as electrostatic plotters and graphic terminals.
