Greetings everyone. I use r.sun for solar radiation modelling in the Philippines. I have a few questions and clarifications and I hope you can indulge me:
1. Aside from NCSU-OSGeoREL (whose resources on r.sun I'm very much thankful for), are there anyone else out there working on r.sun? 2. Has the solar position algorithm in r.sun been updated or what is the solar position algorithm that it uses? SOLPOS? SPA? Will using one or the other have significant effects on the results? 3. I also work with LiDAR and other high resolution data, is it advisable to use multi-threading with r.sun? 4. I'm currently working on Python scripts to compute monthly average solar radiation values using using the average day of the month given by Duffie and Beckman (Solar Engineering and Thermal Processes, 1991) as well as running r.sun for large high-resolution rasters which I'd like to share with the community, if I do finish them. 5. Lastly, is there any effort or interest out there for creating a 3D version of r.sun? One that computes for the solar radiation received by an entire building and not just its roof. I've read about v.sun but I don't think it ever made it to GRASS. Your replies and responses will be highly appreciated. Thank you. Regards, Ben Hur -- *Engr. Ben Hur S.
