#610: r.sun: incidout uses 0 instead of NULL ---------------------+------------------------------------------------------ Reporter: hamish | Owner: [email protected] Type: defect | Status: new Priority: normal | Milestone: 6.5.0 Component: Raster | Version: 6.4.0 RCs Resolution: | Keywords: r.sun Platform: All | Cpu: All ---------------------+------------------------------------------------------ Comment (by hamish):
Replying to [comment:8 hamish]: > now, any ideas about why the western most column is all nulls? > consequence of not supplying aspect/slope maps?? weird, if I zoom in to be entirely within elevation.dem, then run with slope=slope and aspect=aspect, now the southern most row and eastern most column are not NULL. I guess that's just because those two edges have only NULL between them and the sun rising in the south-east that day, so no way of knowing that they're on a downslope or not.
