VMOD is a python-based object oriented framework. Its main purpose is to model multiple types of geodetic data including:
- GNSS
- InSAR
- Level
- EDM
- Tilt
These observations can be interpreted with one or more analytical models that represent pressurized sources such as:
- Pressurized sphere in elastic medium
- Pressurized sphere in viscoelastic medium
- Pressurized sphere in a viscoelastic shell in elastic medium
- Pressurized prolate spheroid in elastic medium
- Dislocation (Fault/Sill) in elastic medium
- Penny shaped crack in elastic medium
- Point source in elastic medium
- Wellsite in porelastic medium
- Ring fault in elastic medium
- Regularized fault/sill in elastic medium
- Open conduit in elastic medium
The framework offers two different inversion techniques to solve for the source parameters:
- Non-linear least squares
- Bayesian approach
The inversions can include one or multiple data types in the inversion and the model can be composed by multiple sources. The user can customize or inherit current models to create complexer geometries.
