#3614: r.relief: estimate solar altitude and azimuth for given date and time
-------------------------------------------------+-------------------------
Reporter: mmetz | Owner: grass-dev@…
Type: enhancement | Status: new
Priority: normal | Milestone: 7.6.0
Component: Raster | Version: svn-trunk
Keywords: r.relief, r.sunhours, solar | CPU: All

r.relief uses solar altitude (default 30 degrees) and azimuth (default 270
degrees) to produce a shaded relief. It would be nice to have a mechanism
to estimate solar altitude and azimuth for a given date and time and the
current region.
This could be done with the solpos algorithm as used in r.sunhours, or
r.sunhours gets enhanced to optionally not produce a raster map, but print
estimates for the current region's center.
