[GRASS-user] r.sun for multiple days

2014-07-08 Thread Tyler Smith
Hello, I'm preparing some maps for use in a MAXENT ecological niche modelling analysis. We're going to use solar radiation as one of the predictors, so will be using the GRASS r.sun command to generate our input rasters. r.sun provides the solar radiation for a single day of the year. My question
