Hi David,

Yes I saw your poster. 

For now, the attached zip file gives the velocity grids that I made for the NGS that are incorporated into their HTDP software (see http://www.ngs.noaa.gov/TOOLS/Htdp/Htdp.html ). The grids are for different regions at different scales, see Table 3 of  the report that's included. They are not at 1 km grid spacing. I could generate a 1 km grid at some point if necessary but that will take a while. Note that my velocity field is extracted from a physical model (not a smoothed version of the GPS) that includes fault slip rates, so faults will show up as high strain rate regions because the velocity field attempts to reflect the long term rates. the frame is itrf 2005

The .info files contain: (V-velocity in mm/yr; S- 1-sigma in mm/yr) (2f9.3, 19(1x,f10.2), 2x, a4 )
items 1-2: Lon Lat 
items 3-6: Ve Vn Se Sn for total velocity (what you want)
7-11:  Ve Vn Se Sn rho for rotational part of field
12-15: Ve Vn Se Sn for anelastic strain rate part of field
16-21: Ve Vn Se Sn Vz Sz for elastic part (fault locking) of field
