What is the difference between photogrammetry and cartography?

Photogrammetry vs. Cartography: Understanding the Differences

Photogrammetry Overview

• Definition: Photogrammetry is a technique used to obtain accurate measurements and 3D information from two-dimensional photographs.

• Process: It involves the analysis of overlapping images to create 3D models, leveraging the principles of triangulation for precise measurements.

• Applications: Photogrammetry finds applications in various fields, including topographic mapping, architecture, forestry, and geology.

Cartography Overview

• Definition: Cartography is the science and art of map-making, encompassing the design, production, and interpretation of maps.

• Process: Cartography involves the representation of spatial information on a map, incorporating data from various sources to create a visual representation of the Earth's surface.

• Applications: Cartography is essential for navigation, land-use planning, environmental studies, and a wide range of other disciplines.

Key Differences Between Photogrammetry and Cartography

1. Nature of Discipline

• Photogrammetry: Focuses on the extraction of measurable data and three-dimensional information from photographs.

• Cartography: Primarily deals with the creation and interpretation of maps for visual communication.

2. Methodology

• Photogrammetry: Involves the use of overlapping images and triangulation for accurate measurement and modeling.

• Cartography: Utilizes various data sources, including surveys, satellite imagery, and geographic information systems (GIS), to create maps.

3. Output

• Photogrammetry: Outputs detailed 3D models, point clouds, and terrain information.

• Cartography: Outputs traditional paper maps or digital maps for navigation and analysis.
