Which of the following is NOT a type of raster data?

The correct response identifies vector graphics as the type of data that is not classified as raster data. Raster data, which is structured as a grid of pixels or cells, represents information through continuous data values, typically for images or surface representations.

Classified images are a type of raster data as they categorize pixel values into specific classes, which can be particularly useful for land cover classification. Surfaces, such as Digital Elevation Models (DEMs), also utilize raster data to represent elevation or other continuous phenomena across a geographic area. Remotely sensed imagery, like satellite images, is inherently raster data as it captures information in pixel grids corresponding to geographic locations on the earth.

In contrast, vector graphics represent data through distinct geometrical shapes like points, lines, and polygons. They are primarily used to convey discrete features rather than continuous phenomena, which differentiates them significantly from raster data types.
