Raster Data & Vector data. Raster Data: A raster consists of a matrix of cells (or pixels) organized into rows and columns (or a grid) where each cell contains a value representing information, such as temperature. The raster data are the data that have individual pixels where each pixel has its spatial location in referenced to real earth.

In the vector world, we have points, lines, and polygons that consist of vertices and paths. Vector and raster data both have their advantages and A vector GIS works by storing three types of geography Points (a power pole), lines (a power line) and polygons (a power utility service area) in a geographical database, and their attributes are stored in a separate database. Raster GISs (grid cell) work by storing attribute data as grid cell values. There are two essential methods used to store information in a Geographic Information System – GIS for both reflections: Raster and Vector Data Model.

• Geographic features stored in a GIS can be considered as one of three types: • points: no area at this scale (e.g. building, tower). Other more comprehensive GIS offerings provide both integrated raster and vector analysis techniques.

Where vector data (coordinates that create an image) is somewhat abstract, raster data is quite literal. Raster data is grid or pixel based. Commonly found as aerial surveys, topographic maps, and satellite imagery, raster file extensions include TIFF, PNG, and JPEG.. In GIS mapping, raster data generally represents surfaces.. Unlike vector data, raster data cannot be scaled infinitely.

Mastering QGIS is designed to bring users who want to go beyond the basics of QGIS to an advanced level of Georeferencing a raster to a vector. When georeferencing, you should look for well-defined objects within your images, such as road intersections or land features. This way you can be certain that you are referencing the same location in both the raster and aligned layers. GIS data represents real items such as roads, rivers, urban areas, place labels, railway, tourist destinations, town labels etc.
