Lines are essential for depicting networks and transportation routes accurately.
Polygons
Polygons enclose areas defined by connecting multiple points and forming closed shapes.
They represent regions such as parks, buildings, or administrative boundaries on maps.
Polygons are vital for spatial analysis involving the calculation of areas and perimeters.
Raster Data
Grids
Grids consist of cells arranged in rows and columns to form a structured layout.
Each cell contains information representing a specific location within the grid system.
Grids facilitate the visualization of continuous phenomena like elevation or temperature.
Cells
Cells, also known as pixels, are the smallest units in raster data representing values or attributes.
They store data related to color intensity, elevation, land cover types, or other characteristics.
Cells enable detailed analysis and interpretation of spatial patterns within raster datasets.
