[Qgis-developer] Data Download Framework [was [Qgis-user] SRTM-plug-in?]

[Alex M]

Short summary, after brief discussion about if there was a plugin to
pull SRTM (DEM) data for the canvas (which we never found), we turned to
discussing the possibility of build a framework for public data
downloading by canvas extent.

We want to avoid duplication of the same common core functionality, and
make it easy to plug new data in, and for users to be able to find what
they're looking for.

Ideally to me this is just an improvement to CSW, WCS and WFS. However
many such data sets don't exist under services, and are just file based
downloads.

This email is to gauge interest in co-developing such an option in QGIS.

Ideas welcome and encouraged.

Thanks,
Alex

A framework for the common parts would be nice, or an easily clone-able
basic plugin that just needs a specialized function to each service.

Of course, this is kind of the point of CSW, WCS and WFS standards. And
we really should encourage the use of standards.

This idea is similar to the getData function of the Raster package in R:
http://www.rdocumentation.org/packages/raster/functions/getData

Which does include the 90m SRTM already processed (CGIAR version
http://srtm.csi.cgiar.org/)

I'd be interested in moving this discussion to the developer list and
participating. I'm involved with the management of the data for the
above mentioned R function.

Thanks,
Alex
