12/10/2023 0 Comments Vector vs raster tiles mapIn simpler terms, it’s a rectangle filled with individual pixels of color. Raster data, known as imagery, is described by a rectangular grid with simple information filling each cell. A user doesn’t need to see every leaf on a tree when all they’re looking for is the road. The human brain is more capable of processing map information when it’s been preformatted with distinguishable colors and styles. Almost all maps used for navigation are rendered in vector style with shapes and simple colors denoting what the area is. They can be whatever the data producer wants them to be, road names, soil conditions, population information, water depth. A vector tends to have attributes associated with it describing the nature of its existence. The result is that a vector map that takes up 1 gigabyte of data, would take up hundreds of gigabytes if it was a similar resolution raster map. A house that may take hundreds of pixels to render clearly in a raster map may only take 4 points in a vector map. It’s more space-efficient than raster data. A raster image is fairly static once produced, but a vector map can be rendered in any number of ways such as different color schemes for day and night. It can be styled in any way the application wants. However, there are several advantages to vector map data: Its complicated nature means it will often be slower to render than simple imagery. As these shapes can be made up of any number of points, even into the tens or hundreds of thousands, they’re more complicated to render than imagery. Vector data is described as lines, points, and areas. Map data comes in 2 categories: Vector and Raster.
