Hello to everybody,
I have to prepair simulations for a sunpower plant in project, considering the
areas in shadow in the plant in certain sample days of the year in the whole
day. The use of the plugin Hillshade is very easy to understand, but I cannot
understand how to obtain a binary raster with value 1 for pixels in shade
(colored in black) and 0 for the others (to see them transparent). I did it few
years ago with ArcGIS the same task and it was really simple to achieve the
desired result, while the same result with QGIS seems to me not so easy to
do... Can anybody tell me how to do it?
Thank you in advance for your help,
Giuseppe Anardu
GRASS r.sun algorithm is intended for calculating solar radiation, I
believe it includes topography based shading in it's formula.
Enjoy,
Alex
