About us
Services of ICGEM
• Collecting and archiving of all existing global gravity field models
• Web interface for getting access to global gravity field models
• Web-based visualization of the gravity field models, their differences, and their time variation
• Web-based service for calculating different functionals of the gravity field models
• Tutorials on spherical harmonics and the theory of the calculation service
• Providing a Digital Object Identifier (DOI) for the data set of the model (the coefficients)
