A set of regularly spaced and contiguous cells with associated numerical values arranged in rows
and columns are called as :
Raster Definition: Cells in Rows and Columns
The question describes a data structure characterized by:
- Regularly spaced cells
- Contiguous arrangement
- Numerical values associated with cells
- Arrangement in rows and columns
This structure is the fundamental definition of a Raster data model.
Comparing Options
Let's analyze the options:
- Datum: Refers to a reference point or system used in geodesy and cartography. Not related to cell arrangement.
- Diagram: A general term for a visual representation, not specific to cell-based data.
- Raster: Represents data as a grid of cells (pixels) arranged in rows and columns, each containing a value. This matches the description perfectly.
- Vector: Represents geographic features using points, lines, and polygons defined by coordinates. It's fundamentally different from a grid of cells.
Conclusion on Raster Data
Based on the definition provided, the arrangement of regularly spaced, contiguous cells with numerical values in rows and columns precisely describes Raster data.
