When I read my shapefile I get this attributes:
S = shaperead('nsrdb_9814_dni_ovit.shp', 'UseGeoCoords', true)
1716115×1 struct array with fields:
Where Geometry is 'Polygon' and DNI is the Direct Normal Irradiance of solar radiation:
I need to plot a result like this (where DNI is the scale for the colormap):
But I have a problem: the structure S is too big for my PC with 16GB of ram (out of memory error) and I didn't see the final result (with smaller pieces of S I can't see if I am in the right direction).
The ultimate question: How can I control the DNI scale to get that result (with hot colormap).
Thank you very much!
