The third hardware componentis the printer/plotter. These devices are used to produce a hardcopy map. There are several types of printers including: matrix, inkjet/bubblejet and laser. GIS data represents real items such as roads, rivers, urban areas, place labels, railway, tourist destinations, town labels etc. with digital data deciding the combination. A geodatabase is a databases that is in some way referenced to locations on earth. Customarily, there are two wide methods used to store data in a GIS; raster images and vector.

2021-04-24 · 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. Converting between raster and vector formats allows you to make use of both raster and vector data when solving a GIS problem, as well as using the various analysis methods unique to these two forms of geographic data. This increases the flexibility you have when considering data sources and processing methods for solving a GIS problem. In vector data the lines on the map are determined by a particular phenomena.

Raster vs vector. Both types of data are very useful, but there are important differences. In instances where they did, at least superficially, the vector datasets were first converted to raster format before being inputted into, say, a query in GIS software. So shunned were the issue of joining raster and vector datasets that dealing with them in isolation became somewhat of an industry-standard, mostly because it was – and perhaps still is – the case in Arc-GIS and GRASS GIS software. A common use of raster data in a GIS is as a background display for other feature layers.
