GNSS Deformation Analysis

Gnss Strain

Compute 2D strain rate tensor from GNSS station velocities.

Uses least-squares inversion of the velocity gradient tensor to compute the strain rate field including principal strains, dilatation, maximum shear, and rotation rate. Requires >= 3 stations.

Parameters (JSON body):

  • station_lat : list[float] -- Station latitudes (degrees)
  • station_lon : list[float] -- Station longitudes (degrees)
  • north_vel : list[float] -- North velocity components (mm/yr)
  • east_vel : list[float] -- East velocity components (mm/yr)

Returns strain rate tensor components in nanostrain/yr, principal strains, dilatation, max shear, and rotation rate.

Pricing: Included in subscription tiers (legacy list price: GET /api/v1/billing/pricing).
