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.

Other Types

TIN (Triangulated Irregular Network)

  • A TIN (Triangulated Irregular Network) is a type of vector data that uses irregularly spaced points to create triangles.

  • It is particularly useful for modeling terrain surfaces with varying elevations and complex geometries.

  • A TIN (Triangulated Irregular Network) enhances 3D visualization capabilities in spatial analysis.

3D Data

  • 3D Data, also known as three-dimensional spatial data, adds depth information to geographic representations.

  • It enables the visualization of landscapes, buildings, and infrastructure in a realistic manner.

  • 3D Data enhances the accuracy and realism of geospatial models for urban planning and architectural design.
