Figures showing the bounding surfaces of a tesseroid (spherical prism)

View of a tesseroid (spherical prism) in a geocentric coordinate system. Red planes show the six bounding surfaces of a tesseroid: two parallels, two meridians, and two concentric spheres. This figure is used in the Tesseroids (http://tesseroids.leouieda.com) software documentation. Created using Inkscape (https://inkscape.org).
