Name a common output format for GIS data.

A shapefile is a widely used format for storing the geometric location and attribute information of geographic features. It is a popular output format in Geographic Information Systems (GIS) because it is specifically designed for spatial data, allowing for the efficient storage and retrieval of both vector data (like points, lines, and polygons) and their associated attributes.

Shapefiles can be easily integrated with various GIS software applications, making them essential for spatial analysis and mapping tasks in geospatial projects. Unlike other formats like CSV files or XLS spreadsheets, which are primarily designed for tabular data, shapefiles maintain the spatial structure needed for geographical analysis. This capability to handle complex geospatial data makes shapefiles a fundamental format in the GIS community.
