Which file format is commonly associated with vector geographic data?

• A. Shapefiles
• B. GeoTIFF
• C. CSV
• D. PDF

Answer: (A)

Vector geographic data represents features as precise geometry—points, lines, and polygons—and often includes an accompanying attribute table. Shapefiles have long been the standard format for storing that vector geometry along with attributes, using a set of related files that together describe the shapes and their data. This makes shapefiles the most natural and commonly associated format for vector data in many GIS workflows.

GeoTIFF is a raster format designed for grid-based imagery, not geometry. CSV can store coordinates and attributes in a table, but it doesn’t inherently preserve vector geometry or topology. PDF is a document format and not used for native GIS vector data storage.

So, for vector geographic data, shapefiles are the best-known and most commonly associated format.
