H'mmm.... Since no-one here is directly engaged with these people, I'm
wondering how to channel experienced contributions to this process...
I've tried, but have been rebuffed. Was told that data interchange is
too "researchy" for the " AR industry" And here they are running off,
missing some pretty important issues.
Talking to ourselves about this is somewhat silly. Somehow the key
players need to be engaged here. Mobilzy - the proponents of this
inititive are already shovelling in 2d KML into their service, oblivious
of some of the issues we've thrashed to death here re, CRSs, epsg

" Since mid 2009 companies started to develop augmented reality (AR)
applications for the latest generation of smart phones (iPhone, Android,
...). Many of those applications overlay the phone's cam view with
interesting location aware data. Such information can be points of
interest from travel or tourist services or real time data for instance
There is already a standard available to describe geo data. KML is an
open standard officially named the OpenGIS KML Encoding Standard (OGC
KML). It is maintained by the Open Geospatial Consortium, Inc. (OGC).
The complete specification for OGC KML can be found at
Many companies and organizations have their geo data already available
in KML. Therefore it makes perfect sense to base the AR data on KML and
enrich it with custom extensions.
The basic idea behind this specification is that data that is prepared
using this specification can be viewed on augmented reality browsers
like Wikitude but also in Google Earth. Augmented reality browsers can
include an open URL dialog where the user can enter an URL pointing to a
valid ARML document. For instance such a document can contain all
affiliates of a company. People can easily bookmark those URLs.
Augmented reality (AR) specific data is defined in an own KML extension
Very Simple ARML Document
The simplest ARML documents are just plain KML. Any ARML compliant
browser must support these documents. Only the elements <kml>,
<Document>, <Placemark>, <name>, <description>, <Point>, <coordinates>
01.<?xml version="1.0" encoding="UTF-8"?>
04. <Placemark id="153630">
07. Getreidegasse (also known as Grain Lane) is a busy
shopping street in the Old Town section of Salzburg.
08. The house at no. 9 Getreidegasse is where the famed
Wolfgang Amadeus Mozart was born and lived ...
