<br>
exactly in those areas I have a problem of understanding the OSM

<br>
No, as explained, I do intent to calculate edge weights based on
OSM and elevation data. Is this a trivial change?<br>
<br>
And then I "store" this mixed weights in-memory but this is only a
configuration to make it storing on disc. And would it make a
difference? I read somewhere that "storing" could be also
in-memory with the rise of NoSQL databases this makes indeed sense

What did you mean here? This would make a difference for the
elevation provider license not for the OSM license (?)<br>
<br>

<br>
Of course, but I think this would be another issue. I would like
to understand the OSM implications first :) !<br>

your definition of the "routing database". If you store the
elevation data in the original grid-based form and you request
elevation data on-demand for lat/lon coords without long-term
storing of lat/lon + elevation pairs, then I don't really see the
two data sources "infecting" one another in legal terms.

If it's SRTM it's just public domain isn't it? So
if the resulting database is under ODBL I can't
see that being a problem.<br>

Subject: [OSM-legal-talk] Elevation / SRTM
data<br>

<div><font face="Courier
New,Courier,monospace">Hi there,<br>
<br>
how would like to know how I could
integrate SRTM data with OSM data. It<br>
is not for a mapping service where I could
overlay the elevation<br>
curves/data and keep it separate. It is
for my routing engine<br>
GraphHopper where I would need to do the
following:<br>
<br>
* to calculate the distance I take the
latitudes and longitudes from<br>
OSM, to guess the speed I take the highway
and other tags. Then, with<br>
the help of the SRTM data I modify this
distance and speed to be more<br>
real world.<br>
* to create an elevation profile of the
resulting path. This should be<br>
simple (?) as the elevation data could be
in a separate database and<br>
just fetched on demand.<br>
<br>
Will the resulting routing database fall
under ODbL which the providers<br>
probably do not want as their elevation
data could be guessed or even<br>
recalculated (with a bit effort)?<br>
<br>
Sorry, if this is a stupid question. I'm
really new to OSM licensing<br>
world :) and there was a similar question
but this was regarding hill<br>
shading and the old license:<br>
