PyGPS

Extracing displacement and atmospheric parameters from GPS products for improving InSAR geodesy.

GPS products from Nevada Geodetic Laboratory and UNAVCO are supported.

• Search available GPS stations over an interested region [yes]
• Download the GPS products of interest [yes]
• Extract the spatio-temporal displacement and atmospheric products (time-series or near SAR epoch) [yes]
• Mitigating the atmospheric effects for InSAR geodesy [not yet]
• Generate high-resolution atmospheric water vapor map by fusing InSAR and GPS measurement [not yet]
