Hi!<br>
<br>
[sorry I missed the beginning of the discussion: I was not registered yet]<br>
<br>
So, when I proposed you to talk about things from MeteoIO that could possibly be interesting for QGIS, I had the following in mind:<br>
*the calculation of solar irradiance on the ground, with terrain shadowing. Here, we are not talking about the (unfortunately) standard (pseudo)shading that is usually done in GIS (ie: adding shadows to highlight the terrain contours), but real shading. The radiation would only be valid for clear sky (we can not easily get the cloud information), but it would provide a valid potential solar irradiance information for a given date+time. We could easily also provide a yearly/montly/daily potential average solar irradiance layer.<br>
*we also offer a bunch of spatial interpolation algorithms (the kriging is not yet 100% finished, but almost). These are the tools that you need to transform point measurements in distributed values over a DEM (we use it for meteorological parameters, the whole thing was initially invented for mining)<br>
</blockquote><br></div>Just a quick note: both (real shading, kriging) are already implemented in SAGA GIS. If a good plugin is available for saga, perhaps better to focus on other functionality.<br>Anyway, let's hope that a processing framework leads to less duplicated code in the long term.<br>
