geoidmodellering
Geoidmodellering is the process of creating a mathematical representation of the geoid. The geoid is an equipotential surface of the Earth's gravity field that best fits mean sea level. It is an irregular surface because the Earth's mass distribution is not uniform. Geoid models are essential for many surveying and mapping applications, particularly for determining accurate elevations.
Traditional geoid models were derived from gravity measurements made at sea and on land. However, these measurements
The process of geoid modeling typically involves several steps. First, raw gravity data is collected and processed
Geoid models are crucial for converting between different vertical datums. For instance, they are used to transform
