As more and more sailors and sailors use chart plotter and map navigation apps on their smartphones and tablets, it is essential to understand the difference between raster, vector, and electronic maps. Although vector charts do not have the visual appeal of grids and charts, they have many advantages, such as their ease of use and ease of use.
Vector Chart vs. Raster Chart
A vector chart does not yet cover many areas globally, and therefore must use a raster chart. For example, storing grid diagrams for a single region will occupy a large area of up to 1,000 square meters. Storing raster charts in a single region can exceed the storage space for vector charts of an entire country.
If you compare raster and vector charts concerning the land information offered, you will find that the ADMIRALTY Vector Chart Service provides much more information about land location than the grids. There are many places in the world where vector maps are not available, and the crew may have to use a grid chart or pretend to.
British Columbia, for example, has better coverage than the grid in remote areas, but that changed when the agency moved to replace it with vector charts.
The first column shows a standard Admiralty grid diagram. The second shows the same area in the opposite view. The third column shows a very popular vector diagram system that runs against the official S57 vector data.
The vector charts used are C maps, and the information is taken from the official S-52 charts. Vector charts will not have the hand-drawn appearance that a raster chart might have in some places, but they are more accurate.
Easy to use Vector Chart than Raster
You can zoom in and zoom out much further than a raster chart with simple navigation, and the letters and symbols always remain the same size. For example, vector diagram software can keep text in a fixed readable size, regardless of the zoom factor.
The vector format also gives you more flexibility when using the charts: they can be zoomed in, resized, or moved up and down much more than raster charts. In addition to scanning and paper diagrams, the features of a vector diagram can also be defined as geometric primitives, polygons, points, etc.
If you scan one raster chart at a time, zoom in and out, reach the edge of one chart, and jump to another. With a vector chart, you can turn around and zoom in again, which proves to be the right way, no matter how the chart aligns.
The reality that the raster charts match the paper charts means that you can use the charts the same way regardless of their orientation, even if they are zoomed in or highlighted.
Smaller boats have to use cartridges, while larger boats can choose which cartridge they use, but there is no real difference between a grid and a vector system on board. The “grid” format of GPS maps and plotters is often misused, especially in small boats with many spaces.
Accurate and Reliable Navigation
While raster and vector maps for electronic navigation are generally equally accurate and reliable, the choice between them is a matter of personal taste. I find it much easier to decide when I go through the comparison between vector and raster charts.
When I load my first vector chart, I fill the list with all functions I discovered in this particular vector diagram. Once I have made a list of the essential features of my current and future GPS maps and plotters, I start defining the chart in terms of its size, shape, and other features.
While the raster format is an exact photographic image on paper, the vector format can be overlaid with data displayed in a paper diagram. Since a vector chart is layered, you can choose whether you want as much or as little information as you want to display it.
Although there are no features on a grid diagram, I can quickly get information about features not printed on the diagram itself. A vector chart can contain up to 100 layers, and since they are superimposed, each layer has its properties, such as size, shape, and shape of the data.
Although it is in raster format, it is used on the Internet as a logo, illustration, or engraving. PDFs and are used on our website for logo illustrations and engravings, and many other applications.
A vector diagram is used to create a graphical format to represent diagrams in a more schematic method. A digitized copy of a completely new diagram is created in a scalable vector format. It is much easier to digitize than a raster version of the same diagram in any other format.
A vector chart is a raster chart that contains information from a paper chart and is rendered into an image by a computer in flight. The computer displays the vector information in a vector format that cartographers know is helpful.
A scanned image of the paper diagrams is embedded in both the grids and the vector diagrams, and the Enc is the digital image (ep).
