Vektorandmete

Vektorandmete, often translated as vector data, is a method of representing geographic information in a digital format. Instead of using a grid of pixels like raster data, vector data uses geometric primitives such as points, lines, and polygons to represent features on a map. Each point is defined by a pair of coordinates, lines are a series of connected points, and polygons are closed lines.

These geometric shapes are associated with attribute data, which describes the characteristics of the features. For example, a point might represent a city, with attributes including its name, population, and elevation. A line could represent a road, with attributes like its name, speed limit, and surface type. Polygons are used for areas, such as lakes, countries, or land parcels, and their attributes could include names, types, or ownership.

Vector data is particularly well-suited for representing discrete features with well-defined boundaries. Its advantages include high precision, scalability without loss of quality, and efficient storage for sparse datasets. It is widely used in geographic information systems (GIS) for applications such as mapping, navigation, land management, and environmental analysis. The ability to query and analyze based on both spatial location and attribute information makes vector data a fundamental component of modern geospatial technologies.
