Im currently trying to collect some weather data from an API, and to reduce the amount of API calls im trying to batch the calls on 0.5degree longitude and latitude chunks due to its resolution. I had this code def round_to_grid_center(coordinate,grid_spacing=0.5 ): offset = grid_spacing / 2 return round(((coordinate - offset) / grid_spacing)) * grid_spacing + offset but this function rounded values at 0.5 down to 0.25 instead of up to 0.75, so i added this fix. It works for me, but I'm sure there is a better more efficient method to round the coordinates to their closest grid square centre. Please let me know! def round_to_grid_center(coordinate,grid_spacing=0.5 ): #temp fix for round down error if ((coordinate % 0.5)== 0 and (coordinate % 1 )!= 0): offset = grid_spacing / 2 return round(((coordinate + 0.01 - offset) / grid_spacing)) * grid_spacing + offset else: offset = grid_spacing / 2 return round(((coordinate - offset) / grid_spacing)) * grid_spacing + offset Continue reading...
