Vector

Vector files are one of the most important data formats in Geographic Information Systems (GIS), used to represent real-world geographic features with high spatial accuracy. They store data using three primary geometry types: points, lines, and polygons. Points represent individual locations such as wells, landmarks, utility poles, or survey markers. Lines model linear features like roads, rivers, railways, pipelines, and power lines, while polygons define enclosed areas such as land parcels, forests, lakes, buildings, and administrative boundaries. Unlike raster data, vector data stores precise coordinates, allowing accurate measurement of distances, areas, and perimeters without losing quality when scaled. Each feature can also include attribute information, such as names, classifications, ownership records, or demographic data, enabling spatial and non-spatial analysis. Because of their precision and flexibility, vector files are widely used in cartography, urban planning, transportation, environmental management, utility mapping, land administration, and infrastructure development, making them essential for mapping, visualization, spatial analysis, and informed decision-making.
