Thread: Flinn-Engdahl implementation

Hello Fabien,

The IRIS Flinn-Engdahl service's underlying code is indeed the feregion.plPERL script you mention in your email.

So, it is just PERL under the hood and not Python.

Regards,

Rich Karstens

Hi,

I would like to translate this script to Python :
ftp://hazards.cr.usgs.gov/feregion/fe_1995/feregion.pl
This is already a Python implementation (though ObsPy) allowing to
query Iris webservice but it can be slow for a bunch of coordinates so
I would like to resolve coordinate to region locally.

What is the language used for the webservice implementation ? If it's
Python, does the code is open ? (To be added to ObsPy)

Cheers,
Fabien

Hi Fabien,

I have a translation to C if this is of interest to you.

Ciao,

Anthony


feregion.c :
