Surveying, Mapping, and Geodesy
Surveying
Surveying is a set of technical and scientific operations used to determine the spatial position of points to represent a plane land surface and its elements. Common units used in surveying include:
- Length: meter
- Area: square meter or hectare (10,000 m2)
- Angle: Grad
Cartography
Cartography is the science that studies the different methods and systems used to represent part or all of the Earth's surface on a plane.
Geodesy
Geodesy is the science that studies the shape and dimensions of the Earth.
Map Projections
Map projections aim to minimize distortions caused by transforming a three-dimensional surface into a two-dimensional plane. These distortions can be linear, angular, or surface-related. Different types... Continue reading "Surveying, Mapping, and Geodesy Fundamentals" »
