terrainShadingMask is a free collection of terrain masks for various locations. They are given in geometrical (.obj files) and textual (.hor files) forms.
A terrain shading mask is a diagram which maps the silhouette of the surrounding terrain (hills, valleys, mountains, tree tops...) around the chosen location.
Building simulation softwares (IES VE, Trnsys 3D, Design Builder...) can use the .obj geometry files, while solar-photovoltaic-thermal software (PV*SOL, PVsyst...) can use .hor files.
