KOMPAS.com – Vector data is a type of data that is often used in Geographic Information Systems (GIS).
Through vector data, each spatial object is represented as one entity consisting of location information and attributes.
What is vector data in geographic information systems?
Understanding vector data
According to Chairul Rizal, et al in the book Geographic Information Systems (2023), vector data is data used to represent spatial objects in the real world.
Longley et al., define vector data as a representation of objects in a geographic information system, which consists of points, lines and polygons.

These three points have locations and attributes related to the spatial object.
Quoted from the book Geographic Information Systems and Their Applications in the Field of Geography (2021) by Jumadi et al., vector data displays spatial patterns with coordinates, so it can be used for spatial analysis.
In general, vector data represents the Earth as an object that contains lines, polygons, points and nodes (the intersection of two lines).
In conclusion, the definition of vector data is data that represents spatial objects in the real world, by displaying points, lines and polygons.
Vector data function
One of the functions of vector data in Geographic Information Systems (GIS) is to analyze the accuracy of the position of an area or region.
Vector data functions to define the spatial relationships of various existing features, namely points, lines and polygons.

Another function of vector data is that it is widely used in GIS applications or data processing, such as creating digital maps or others.
Vector data also functions to create network mapping and regional modeling.
If concluded, the function of vector data is:
- Analyzing the accuracy of the position of an area or region
- Defines the spatial relationships of various features
- Create digital maps or other GIS applications
- Create network maps and regional modeling.
