color=#0000ff size=2>In the thesis you will find a link to <A
href="http://www.openstreetmap.org/">http://www.openstreetmap.org/</A> where
all ( well most ) roads and rr-lines are plotted.</FONT></SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=931211906-20102010><FONT face=Arial
color=#0000ff size=2>It's possible to export an geo area in xml format. Roads
are in diffrent colour and railroads have diffrent shape depending on
trackwidth.</FONT></SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=931211906-20102010><FONT face=Arial
color=#0000ff size=2>An example: look at Landquart in east swiss where there are
2 rr-companies on the same rr-station SBB and RhB and you will note the
diffrences in shape of the track. Same as in Altstätte north of
Landquart.</FONT></SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=931211906-20102010><FONT face=Arial
color=#0000ff size=2>The programs describes the rout of the track ( in 2D ) and
changes the pattern on the track with railwidth.</FONT></SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=931211906-20102010><FONT face=Arial
color=#0000ff size=2>One "challenge" can be to add the 3-dimention ( altitude )
to tracks and roads, to make them usefull in a 3D
sceene. </FONT></SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=931211906-20102010><FONT face=Arial
color=#0000ff size=2>As roads also have diffrent pattern and colour it could be
possible to convert them to different 3D shapes.</FONT></SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=931211906-20102010><FONT face=Arial
color=#0000ff size=2>A second challenge can be to find points in the rr/street
roads where ther can be banks, cutting or bridges. <A
href="http://www.openstreetmap.org">www.openstreetmap.org</A> gives some usefull
hints where rr or/and streets crosses eachother.</FONT></SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=931211906-20102010><FONT face=Arial
color=#0000ff size=2>Anyone who have merged geo-space with openstreetmap

<DIV></DIV>Hello Don<BR><BR>A very interesting topic.<BR><BR>I would have got a
humble question.<BR><BR>Will the provisioning of this data base be a centralized
provisioning or a distributed provisioning?<BR><BR>As some may know, I'm
thinking about simulated railroads by X3D, and my question would
be:<BR><BR>Assume two countries A and B with two railroad operators, who use
such simulator for international trains moving from A to B or vice
versa.<BR><BR>Would the X3D-Earth database be provided by <BR> -
railroad operator A<BR> - railroad operator B<BR> - both
of them somehow "together"<BR> - a third party<BR> -
everyone has an own copy of the whole data base<BR> -
etc.<BR><BR>Just I'm curious (I read that first interest is military interest,
but I wouldn't preclude non-military usage)<BR><BR>Kind regards<BR>Christoph<BR>

Dale, X3D-Earth: Full-Globe Coverage Utilizing Multiple Datasets,<BR>Masters
Thesis, Naval Postgraduate School, Monterey California, September
2010.<BR>Second readers Byounghyun Yoo and Don
McGregor.<BR><BR>Abstract:<BR>U.S. Armed Forces are typically utilizing and
paying for commercial proprietary licensed products to visualize geospatial
scenes, which nevertheless are themselves derived from government-produced
data. This is unsatisfactory. This thesis has developed an open-source,
royalty-free method for generating full-coverage 3D globes using the
Extensible 3D (X3D) Graphics International Standard. Specifically, this thesis
designs and generates robust globe models developing an instance of full
global coverage utilizing X3D-Earth. In order to show interoperability and
“Mash up” capabilities, multiple formats are used, including DTED Level 0 and
NGA-produced satellite imagery. Imagery and corresponding terrain datasets are
preprocessed using image processing and terrain parsing software, creating the
X3D-Earth quad-tree tiles into multiple level-of-detail (LOD) file archives.
Finally, these pyramidal, locale scenes are grouped and connected to form an
overall X3D-Earth globe. Preproces<BR><BR>sing, processing and data storage
are performed with the NPS Hamming Supercomputer. The result of this work is a
methodology for generating X3D-Earth locales that is suitable for massive
replication, optimization and reuse. Current results are promising and further
work is warranted. The ultimate product is expected to further enable new
tactical capabilities, provide direct end-user control of visualization-data
pedigrees, and enable improved operational and navigational situational
awareness for all deployed warfighters.<BR><BR>all the best, Don<BR>-- <BR>Don
