Conclusions:

Opportunities Posed by Advances in Geodesy

- GPS (L2C, L5, L1C) / GNSS - ‘new and improved’ signals may offer signficant changes - high-rate and overlap with seismology - real-time, e.g. co-seismic displacements; EEW & tsunami (e.g., Chile) - zipper arrays; co-located GPS and strong-motion instruments

- InSAR

- LiDAR - geodetic imaging - open data formats - software development - artifact removal

- Image Differencing (e.g., COSI-Corr)
