I'm not an expert, but I think it largely depends on 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.<div>
<br></div><div>Except, of course, if you intend to offer the routing as some kind of high-availability web service which would allow somebody to reconstruct the original elevation data using web scraping.</div><div><br></div>
<div>Of course, all of this also depends on you getting the approval/agreement from the CGIAR data owner to use the elevation data for commercial purposes.</div><div><br></div><div>Best regards,</div><div>Igor Brejc<br><br>

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>

Very much IANAL.<br>

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