How do we define the extent of a raster map?

1. By its resolution and size.

2. By its attribute queries.

3. By its color palette.

4. By the style of visualization used.

The correct answer is: By its resolution and size.

The extent of a raster map is defined by its resolution and size because these elements determine the geographical area that the raster covers and the level of detail (resolution) within that area. The size refers to the total number of pixels that constitute the raster, while the resolution indicates how much ground area each pixel represents. Together, these factors define the spatial boundaries of the dataset, allowing users to understand what geographic features are included and how detailed those features are on the map. In contrast, attribute queries pertain to the data associated with the raster's pixels, not the spatial extent. The color palette is related to how the raster data is visually represented but does not define the spatial extent itself. Similarly, the style of visualization alters the appearance of the raster but does not influence the geographic area it covers. Therefore, it is the combination of resolution and size that accurately defines the extent of a raster map.
