![]() Vector points are one XY coordinate they have no length or width, therefore no area. based on its discrete boundaries.Īnother difference between raster vs vector data is that vector data comes in three types: points, lines, and polygons. These coordinates, also known as vertices, define the shape of an object such as a river, building, forest, road, etc. While raster data is composed of cells in a matrix, vector data is composed of XY coordinates. One of the main differences between raster vs vector data is how it is represented. In an image, each pixel will have a red, green, and blue value, but the value of a pixel could also represent average rainfall, temperature, elevation, CO2 levels, etc.Įvery pixel in a raster dataset is identical in size and shape, and the amount of land each pixel represents is known as the spatial resolution. Each pixel in this grid, also referred to as a cell, contains a value of some sort, which represents a piece of data. Raster data is represented as a matrix of pixels arranged into rows and columns, aka, a grid. So, what is raster vs vector data, and which is best? Below, we’ll dive into everything you need to know about these two data representations. ![]() While attribute data is always represented in tabular format, geospatial data is a bit more varied, as it can be represented in either vector or raster forms. What makes GIS so interesting is that it can handle both attribute data, which describes the characteristics of a feature, and geospatial data, which describes the absolute and relative location of a feature. However, a lot of programs deal with data. Without data, there would be no reason for GIS to exist the whole point of GIS is to create, manage, analyze, and map data.
