Orthogonal
Overview
Orthogonal refers to a coordinate system or projection where the axes are at right angles (90 degrees) to each other, allowing for accurate representation of spatial relationships in a GIS. Orthogonal coordinates simplify distance and area calculations.
Key Concepts
Right angle is a 90-degree angle between axes. Cartesian coordinates use orthogonal X and Y axes. Orthophoto is an aerial image geometrically corrected to uniform scale. Grid system uses orthogonal rows and columns.
Applications
- Cartesian coordinate systems
- Orthophoto production from aerial imagery
- Regular raster grids
- Engineering surveys
