Subject: RE: [emergency] GIS Profiles used in Emergency Services
|
Toby, Glad to hear of your interest in the GML simple features profile
developed for use in EDXL. The profile spec and schema are nearing completion
of the process to become a Committee Specification Draft (CSD). This draft spec and associated schema, as you have probably seen
on related emails, have been approved by vote of the EM-TC to become a
Committee Specification Draft (CSD) following a few remaining steps to complete
in the OASIS approval and registration process. Here’s a link to the location as it appears on the EM-TC
page (points to a location in RIM-SC): http://www.oasis-open.org/apps/org/workgroup/emergency-rim/download.php/43482/EDXLGSF_wd10.zip Keep in mind that, until we have completed the OASIS process,
the draft spec and schema are still not ‘final’. However, I believe
the schema and spec are stable enough to begin to consider how it might be used
in EDXL and perhaps other use. Perhaps Elysa Jones might clarify the status and
access/use in case I might have mis-spoke. Regards, Lew Leinenweber SE Solutions, Inc. 301.351.4485 From: Toby Considine
[mailto:tobyconsidine@gmail.com] On Behalf Of Toby Considine Long-time lurker. Can someone give me a pointer to the GML profiles used in EDXL?
There are many reasons to adopt the same or similar profiles. -
Outages and Additional LEO requirements often coincide -
Emergency “Keep Powered at all costs” locations
often overlap with sites of interest to first responders. Pointers? Thanks tc "A designer knows he has achieved perfection not when there

[mailto:Toby.Considine@gmail.com] Received this note from Bruce yesterday… From: Bartell, Bruce
[mailto:bbartell@xtensible.net] I am looking at the use of ApplicableLocation
in eiDistributeQuote. The way it is structured now I only seem to
be able to access gml:AbstractFeature via the ServiceAreaType. I noticed that serviceArea is part of the
emixInterface substitution group. That group has ServiceDeliveryPoint, PNode,
and other locations applicable to a price. Was the intent to be able to get to the
substitution group, extend the type through EmixInterfaceType, or both? Both would seem to be the best way, if
possible. As I said, right now I can only use gml:AbstractFeature in the
ServiceAreaType. Bruce Bartell Xtensible Solutions It highlights an area that EMIX 1.0 did not go to. The GML AbstractFeature is like many of the EMIX objects; it is
a not-useful-by-itself abstract tub in which you can put all sorts of GIS
information. In EMIX, we specify that an AbstractFeature can fit into an
EmixInterface. We never specified what was in it, though. In general, best practice in GML-derived schemas is to derive
specific types. EMIX leaves that as an exercise for the reader. EMIX specifies
the Profile Level 0 be used. This restricts the features to points, lines, and
polygons. No DR messages sent to all forested areas. No Quotes to all lakefront
properties. An abstract feature can be a collection of features. GML is very large. In a perfect world, with infinite time, we
would meet for just as long on the GIS features as we have on everything else.
We should define something similar to three types of features, name them and
go. A good introduction to these issues is at the Penn State
Geography page on GML https://courseware.e-education.psu.edu/courses/geog585/content/lesson06/11.html At a first guess, I think we need: -
A named “Bounded by” object. All things that are
inside this polygon. We should give it a name. -
Points (and collections of points). What is the meaning? Are all
meters / locations w/I [50 ft] of one of those points subject to a DR event? -
Lines, aka circuits. Do we want to support circuits? Again, are
all Nodes w/I [100 Meters] of a Circuit affected? Possible Shortcut. Emergency Management has been through this
exercise. Perhaps we can re-use their definitions and work. tc "A designer knows he has achieved perfection not when there
