Hi Dev,

As some of you know, Sid, Eric and I have done a little work setting up an 
internet map server (we used MapServer) for the folks at Kruger National 
Park, so that the kruger people could select EML2 documents stored in 
their Metacat server spatially.  The GIS that we are using for interfacing 
the GIS with Metacat is the ESRI Shapefile -- kinda the standard vector 
GIS object these days.  These shapefiles can be used with most GIS's 
(including ArcView, ArcInfo, ArcGIS, GRASS, Geotools, Geoserver, and 
Mapserver).

I thought that some of you may be interested in looking at the tool we 
used for getting the EML2 data out of Metacat and into the Shapefile 
format, so I'm putting the application (runs on RH Linux 7.1 - Fedora 
Core2) online.  The application uses perl to query metacat and the 
shapelib project to injest the EML into a Shapefile.

If you are interested in running the application get the tarfile listed 
below and edit the variables in the metacat_to_shapefile.sh script.  For 
the Kruger prototype mapserver we are running this a cronjob so that the 
shapefile is updated every couple hours, and thus the maps served are 
somewhat dynamic.

Map of all the EML2 documents (with locations) in 
metacat.nceas.ucsb.edu/knb:

Take care.  John
