Which of the following statements with reference to raster data format is/are correct? 1. It has a simple data structure which is compatible with remote sensing imagery. 2. The relationship between cell size and number of cells is expressed as the resolution of the raster. Select the answer using the code given below.

Your answer: —  Â·  Correct: C
Explanation

Raster data is characterized by a simple data structure consisting of a matrix or grid of cells (pixels), where each cell contains a value representing a specific attribute. This structure is inherently compatible with remote sensing imagery, as satellite sensors capture data in a grid-like format. Statement 1 is therefore correct. Regarding statement 2, the resolution of a raster is fundamentally defined by its cell size; smaller cell sizes represent higher spatial resolution. For a fixed geographic extent, the resolution is expressed through the relationship between the cell size and the total number of cells (rows and columns); a higher number of cells within the same area results in smaller cell sizes and thus finer resolution. Consequently, both statements accurately describe the technical characteristics and resolution dynamics of the raster data format.
