Overview    

See Getting Started for a quick overview of the Jules Verne Voyager map tool capabilities.

For items specific to voyaging GEM Global Strain Rate Map, continue to read this GEM Global Strain Rate Map Features Help page.

To learn how to use the grd, gmt, geo, lbl, vel, mon, msc, and/or opt codes to customize a starting view, see Advanced Help: URL customizing.


Voyager GEM Global Strain Rate Map features     The default GEM Global Strain Rate Map uses a texture underlay grid grd=1 showing the 2nd invariant of lithospheric strain rate, with an image overlay of coastal outlines in white — which forces the texture underlay to have a black background in regions of zero strain rate (i.e. lithosphere is assumed to be rigid in the black areas).

The input data (as image overlays) of the GEM Global Strain Rate Map available in the [Features:] menu of Voyager: GEM Global Strain Rate Map are:

[geodetic sites]  http://jules.unavco.org/GEM_GSRM?msc=256 msc = 256   overlay: sites of geodetic horizontal motion measurement
[geodetic velocities]  http://jules.unavco.org/GEM_GSRM?vel=4 vel = 4   overlay: horizontal velocities at the geodetic sites used as input data
