Hi!
How hard/feasible would it be to implement elevation profile/drape line
functionality in PostGIS? Since PostGIS already depends on GDAL I assume making
use of the GDAL API would make this quite easy, such as in the Zoo-Project
service:
http://www.zoo-project.org/trac/browser/trunk/zoo-project/zoo-services/gdal/profile/service.c
Providing functionality that could eventually be used for applications like:
http://www.zoo-project.org/site/ZooWebSite/Demo/GdalProfile (using the code
above)
I’m currently using an ad-hoc PostGIS-function to pull out elevation profiles
from my rasters, but it’s quite slow and CPU intensive and as such does not
make a good fit as a backend service for a web application like the above.
