1 Μαΐ 2024 · What is the difference between raster and vector GIS data? As mentioned, geospatial data can be represented in one of two main types: vector or raster. A comparison of how rivers and lakes are shown as polygons and lines in vector data (top) and as cells in raster data (bottom). Images: Caitlin Dempsey.
Vector vs Raster: A simple way of identifying whether data is in a vector or raster format is to keep zooming in and see if you see the pixels. It is a raster file if you can see those pixels, otherwise it is a vector file. In Figure 6, you can see how a series of polygons would be represented as raster data. Figure 6.
Raster vs vector GIS: They operate differently and are used to address different types of geographical problems. Vector GISs are most suited to applications that involve the social and engineering sciences, and grid cell (raster) systems to applications that involve the natural sciences.

This pic gives a good idea of raster vs. vector representation of data. In Rastor, the area under consideration is divided into equal squares and a characteristic assigned to it.
These two types of spatial data are the backbone of GIS analyses and mapping, each with its unique characteristics, advantages, and applications. This guide aims to demystify vector and raster data, offering insights into their nature, uses, and how to choose between them for your GIS projects.
