Geometrical figures shaping the raster cell and completely covering a flat surface area called___________.

Correct option is C

Tessellations refer to the arrangement of geometric shapes (often squares or hexagons) in a pattern where the shapes cover a flat surface without any gaps or overlaps. In GIS (Geographic Information Systems), tessellations are used to represent raster data, where each cell corresponds to a portion of the Earth's surface.
Information Booster:
· Tessellation is often used in the context of GIS for raster data analysis, where each cell in the tessellation represents an area of the Earth's surface.
· Common shapes used for tessellation include squares and hexagons. Hexagons are especially useful for some applications because they reduce distortion and provide more uniform neighboring distances.
Additional Knowledge: 
Elemental points: Incorrect. Elemental points are basic units used in point data, but they do not refer to geometric shapes covering a surface.
Buffering: Incorrect. Buffering refers to creating zones around a point, line, or polygon to represent proximity or distance in GIS, not the division of space into cells.
Digital Line Graphs: Incorrect. Digital line graphs are vector representations of geographic features, not geometric shapes that cover a surface.
