![]() Line Data– It is used to represent the data that have linear features which contain at least two pairs of coordinates such as X1 Y1, X2 Y2.For example, the location of a house, location of a well etc. It is most commonly used to represent non-adjacent features and discrete data points. Point Data – is represented by one pair of coordinates ( X and Y) and is considered a dimensionless object because it can neither measure its length nor breadth with its data set.As such, vector data tend to define the centres and edges of certain features. It represents in the form of points, lines and polygons depending upon the feature. Vector data models use X and Y coordinates to define the geographic elements. Based on the nature of the display, this data is classified into two models i.e. Image Courtesy:ġ.”Figuur beschrijft fenomeen raster-data en vector-data bij inzoomen” By T.Nijeholt at nl.wikibooks (CC BY-SA 3.Geographic data are geographically referenced data wherein individuals can locate and identify features by a spherical coordinate system i.e. Buckey.” Module 4 – Water Hyacinth, Available here.

The main difference between Raster and Vector Data is that the raster data represents data as a cell or a grid matrix while vector data represents data using sequential points or vertices. Raster data and vector data are two types of spatial data in GIS. However, administrative borders, linear features, roads, and rivers are some examples of vector data. Temperature, air pressure, soil PH, ecotones, elevation, flow, and distance are some example of raster data. Hence, this is also a difference between raster and vector data. Moreover, raster data is simpler than vector data. Data RepresentationĪnother difference between raster and vector data is that raster data represents data in cells or in a grid matrix whereas vector data represents data using sequential points or vertices. Importantly, while raster data is continuous data, vector data is discrete data. Thus, this is the main difference between raster and vector data. Whereas, vector data is a type of spatial data used for storing data that has discrete boundaries. Raster data is a type of spatial data that consists of a matrix of cells organized into rows and columns in which each cell represents specific information. Difference Between Raster and Vector Data Definition Furthermore, it can be expensive to display high-quality colors. It is difficult to simulate them as each unit has a different topological form. Moreover, it is also possible to generalize and update raster data. It also helps to represent accurate graphics. It helps to describe the entire topology. Vector data provides multiple advantages. Moreover, vector data display latitude and longitude using lines, points, polygons, etc. Administrative borders, linear features, roads, and rivers are some examples of vector data. Each vertex contains x coordinate and a y coordinate. Vector data uses sequential points or vertices to represent data. ![]() Moreover, if there is no special hardware or algorithms, the projection transformations can be time-consuming. It can also be difficult to establish network linkages. On the other hand, raster data can cause information loss. They are easier to simulate as all the cells are of the same size and same shape. Chemical concentrations and elevation surface are some examples of raster data. Each cell has a value that represents information. In other words, it is a matrix of cells organized into rows and columns. – Comparison of Key Differences Key Terms ![]() Difference Between Raster and Vector Data In brief, raster data is continuous data whereas vector data is discrete data. It is possible to maintain spatial data as vector data or raster data. One data type or data structure available in GIS is spatial data. Users can visualize, and understand the relationships between geo data in forms of reports, charts, maps etc. Geographic Information System (GIS) is a computer-based tool or technology to manage, analyze and display geographically referenced information. The main difference between raster and vector data is that the raster data represents data as a cell or a grid matrix while vector data represents data using sequential points or vertices.
