Which of the following is a vector data format?

Shapefile is a widely recognized vector data format used in Geographic Information Systems (GIS). Vector data formats represent geographic features using geometric shapes such as points, lines, and polygons. This structure allows for the representation of discrete features like roads, rivers, and land parcels with precise geometric properties.

Shapefiles are composed of various files that work together to store the geometry and attributes of spatial features, making them effective for various GIS applications, including mapping, analysis, and data visualization. Their compatibility with many GIS software programs further solidifies their importance in the field.

In comparison, GeoTIFF and raster graphics are associated with raster data formats, which depict continuous surfaces through a grid of cells or pixels. JPEG is also a raster image format used primarily for compressing images and does not support the complex data structures needed for geographic analysis. Thus, the unique capabilities and characteristics of shapefiles align them with vector data formats, distinguishing them from the other options.
