Which file format is commonly associated with raster data?

1. Shapefile

2. JPEG

3. XML

4. GeoJSON

The correct answer is: JPEG

The file format commonly associated with raster data is JPEG. Raster data refers to information represented in a grid of pixels or cells, where each pixel contains specific information about a corresponding area. JPEG is a widely used format for storing raster images, particularly photographs, due to its efficient compression methods. Raster formats, like JPEG, are primarily used for images and continuously varying data, making them suitable for applications in remote sensing, digital photography, and other scenarios where image representation is crucial. In contrast, Shapefiles are primarily associated with vector data, which represents discrete features like points, lines, and polygons. XML is a markup language that is not specifically tied to raster data but is used for data representation and storage in a wide array of contexts. GeoJSON is a format for encoding geographic data structures using JavaScript Object Notation (JSON), primarily for vector data rather than raster imagery. Therefore, JPEG stands out as the correct answer due to its direct association with raster data representation.
