Gmt Max Net _top_ -

gmt max net gps_data.xyz -T5 -R-120/-110/30/40 -I0.1d -Egrid.nc -Sgaussian -V gmt max net —whether as a scripted workflow or a future built-in module—provides a robust, reference-frame-aware method to locate extreme net displacements in geodetic data. By combining GMT’s vector math, filtering, and statistical tools, it delivers actionable insights for earthquake geology, crustal dynamics, and hazard assessment. Note to users: The exact implementation depends on your GMT version (6.x recommended). Always validate outputs with synthetic data (e.g., using gmt grdmath to create a dipole field) before processing real observations.

Note: Values are highly dependent on Δt and regional tectonic setting. Data: 500 GPS stations, 2008–2023 Command: gmt max net
