EU mapping function

Jos van Schijndel

Eindhoven University of Technology, 2011 April

Abstract This document shows a function in MatLab for the mapping and interpolation of data on

the EU. The function is general applicable. The Matlab Mapping Toolbox is required

Input is a data (txt) file with: Column 1: Longitudes, Column 2: Latitudes, Column 3-n: the

parameters to be mapped

Output see below:

Fig 2. Map of Column 3: Mean external temperature

Fig 4. Map of Column3: Mean indoor solar irradiance in reference building

Fig 6. Map of Column 7: Mean indoor RH of reference building
