[Antelope] code to calculate psa?

[glenn at gi.alaska.edu]

Hi Gabe,

I wrote such a program as part of the AEIC ShakeMap system. This  
system fully integrates Antelope with ShakeMap and pushes ShakeMaps  
produced at AEIC to the USGS ShakeMap servers for Alaska. There is an  
internal report describing this system and a publication is planned.

To remain true to the USGS ShakeMap system we took the C subroutines  
that USGS use to compute pseudo-spectral accelerations, and  
incorporated them into our own C program (db2ewpg). There is a Perl  
wrapper (db2ewpg_wrapper) that calls this C program.

There is another program that goes along with this which reads the  
wfmeas table produced by db2ewpg and produces XML files for ShakeMap.

Does it sound like any of this would help?

Glenn
