Fig. 8.32
Single-scattering albedo maps and perspecitive views of DEMs of lunar highland domes,
constructed based on Figs.

a, b, and d. (
a
) Gruithuisen
γ
and
δ
. The albedo map refers to
1210 nm wavelength, the grey value range is 0-0.4. (
b
) Mons Hansteen. The albedo map refers
to 1978 nm wavelength, the grey value range is 0-0.55. (
c
) Mairan T and Mairan 'middle'. Image
credit: A. Grumpe. The albedo map refers to 1978 nm wavelength, the grey value range is 0-0.55.
The DEMs are shown as perspective views with the albedo-dependent modelled reflectance used
as an overlay. The vertical axis is three times exaggerated
The dome height values independently obtained based on shadow length mea-
surement according to Ashbrook (
1961
) may be used for comparison, yielding a
good consistency with the corresponding values obtained by photoclinometry and
shape from shading (cf. Table
8.1
).
When no ground truth is available, the consistency of height measurements
across several images is a further good indicator of their reliability. Height values
of the domes M3 and M12 were determined based on the images in Figs.
8.22
b
and
8.22
c, which were acquired with different telescopes and CCD cameras from
different locations. The obtained dome heights are 190 m and 230 m in Fig.
