The figure ground plan organizes the primary urban landscape components - plots, streets, constructed spaces, and open spaces [8] – into a diagram of solid and void; the proportions, of which, can be manipulated to create different urban morphologies. If building mass (solid poche) is greater than open space (void), spatial continuity is ...
The solid angle subtended at the corner of a cube (an octant) or spanned by a spherical octant is π /2 sr, one-eight of the solid angle of a sphere. [ 1 ] Solid angles can also be measured in square degrees (1 sr = ( 180/ π ) 2 square degrees), in square arc-minutes and square arc-seconds , or in fractions of the sphere (1 sr = 1 / 4 π ...
