[georss] [OWS-4-SWE] Georss extension

Sun Sep 24 16:14:56 EDT 2006

Re: [OWS-4-SWE] [georss] Georss extensionAhh - gotcha. Perhaps, then, we need a simple xAL schema that then allows the application developer the flexibility to use existing coding schemas (ISO for country codes, SALB for administrative units, Flinn-Engdahl zones/regions or any other designation as required. This would imply an allowed list of region/zone taxonomies and perhaps something like a geo-mime type. 

Cheers

Carl

  Carl,

  But we need worldwide coverage (including oceans), this is beyond political/administrative regions/districts which are already sufficiently covered.  This is truly a location geocoding problem for remote sensing... Would this be in the scope of xAl?
  Looking at SALB, it is interesting to see the battle between FIPS 10-4/ISO 3166-2
  Pat.

  Something else to chew on over the weekend. The United Nations has a project (in progress since 2000 or so) in which they are working with countries to define what they call second level administrative districts. This is a global project called Second Administrative Level Boundaries - SALB. http://www3.who.int/whosis/gis/salb/salb_coding.htm

  The Flinn-Engdahl zones/regions were originally developed for the seismic community - SALB has been developed for the GIS community in concert with the nations - not just one US agency.

  Something to consider.

  Regards

  Carl
