<br><br>I've been thinking a lot about 3D GIS lately, about interoperability of<br>3D objects in real world - virtual worlds like Google earth, Microsoft-<br>virtual earth, NASA wwind, ESRI ARCglobe, companies like Autodesk have
<br>large legacy 3D GIS &CAD systems still moving forward, and no doubt<br>someone like Linden Labs will launch a 3d social apps in a real world -<br>virtual world.. based on geo coordinates instead of 2nd life's random
<br>geography, and even mobile 3Dgis is quickly showing glimmers of<br>promise: mobile augmented reality developers will likely build a<br>geocoded 3D frameworks to hang links on... for services like nokia's<br>MARA prototype (
<a href="http://www.technologyreview.com/Infotech/18291/">http://www.technologyreview.com/Infotech/18291/</a>) ... and<br>a consensus 3D geoweb like GEON ( <a href="http://www.geongrid.org/about.html">http://www.geongrid.org/about.html
</a>)<br>will also be the basis for the worldwide sensorweb, eg. for<br>trans-disciplinary problem solving like macro-ecology, climate models,<br>zoonautic, ( animal born disease) emergency response, &&<br><br>Will we have multiple 3D geowebs? beyond harmonized 2D geodata and
<br>geocoded hypermedia, will 3D data and media producers and service<br>operators have to produce and manage multiple frameworks ( including<br>places, buildings, things - people& avatars ) for each or these<br>environments?
<br><br>So, following digital earth, champion, Tim Foresman's lead - (As<br>Director of Digtal Earth programs for NASA working for vp gore, Tim lead<br>the first DERM - A reference model in the Federal Geospatial Data
<br>Committee and ISO communities in collaboration with the original NASA<br>led Interagency Working Group on Digital Earth. That work is now off<br>on a dusty shelf, out of date, given the future requirements.)<br><br>
I'll be leading sessions at Where2.0<br>(<a href="http://conferences.oreillynet.com/where2007/">http://conferences.oreillynet.com/where2007/</a>) and ISDE5<br>(<a href="http://www.isde5.org/">http://www.isde5.org/</a>
) to raise questions leading to re-starting<br>considering of a consensus reference specification, for a 3D geoweb - a<br>a standard Digital Earth. google, no doubt, sees kml as the answer to<br>these questions, and MS is, no doubt brewing up their own too, clearly
<br>the big guys are going to duke it out from very proprietary<br>perspectives, and it's still not clear that the US gov, OGC, W3C, OR<br>SIGGRAPH communities like x3D focusing on vrml, offers the integrated<br>perspective of the participatoryGIS, FOSS4G and digital graphic arts
<br>communities, here, capability to develop detailed optimum requirements<br>from wide perspectives:<br><br>Let's start again considering, as communities, a meta level layered<br>architectural description for unified earth and geo-related computing,
<br>refining a model including the following topics ( and others) into an<br>ideally coherent and rigorous framework for optimally sharing and using<br>data across all web, geospatial and scientific contexts:<br><br>* geodesics, where experts are still refining descriptions of the shape
<br>of the earth, and where new coordinate systems are argued.<br>* sensor data generation and labelling<br>* geodata and hypermedia coding/decoding/transcoding<br>* open source networked geodata -libraries and feeds- of raw sensor
<br>data, streaming media, tiles, 3D objects , 2Dvectors, polygons, points,<br>text, etc.)<br>* geo metadata models - formal ontologies, logical description, as<br>frameworks for mining informal users' tag systems<br>
* geo server and middleware models for efficient saving, searching, and<br>sharing of all kinds of geodata<br>* sensemanking inference and other spatial intelligence<br>* rendering software for combining many sources of geodata into unified
<br>useful views for many kinds of interaction<br>* user software/ sharing/saving/serving/searching/rendering<br>* human interaction systems, avatars and social nets, gis, mobile gis,<br>3Digs, geoaudio, augmented reality, haptics
<br>* autonomous sensor networks processing geodata.<br>* meta scale geosciences exploring large transdiscipline problem spaces<br>like planetary meteorology, large scale ecosystem modeling,<br>human-ecosystem interaction models, large scale, emergency response,...
<br><br>These are just penciled place holder layers of a hypothetical reference<br>model - that will need to be refined by the appropriate communities.<br><br>I have no idea how to organize a coherent dialog between the e-mail
<br>list communities cc'd here. right now, maybe somewhat loosely<br>connected dialog will be fine. later perhaps starting at where2.0 and<br>ISDE5, maybe some kind of 3D geoweb wiki communities will coalesce to<br>
start organizing these consensus interoperable models.<br><br>See you in San Jose and Berkeley!!<br><br>Mike<br><br>Mike Liebhold<br>Senior Researcher<br>Institute for the Future<br><br><br>_______________________________________________
