Evolution of Apollo 11 landing site map designs




10.12 from the Lunar Sourcebook by G.H. Heiken, D.T. Vaniman, and B.M. French, editors, copyright 1991 by Cambridge University Press, and is reproduced with permission. It is dervied from the 1978 air-brush map of the Defence Mapping Agency and the US Geological Survey. 


5 November 2011 LROC image taken from 25-km altitude


Landing site map visualization: SIMPLE AND EFFECTIVE. Diagram based on the Apollo 11, 12, and 14 Traverses map prepared by the U.S. Geological Survey and published by the Defense Mapping Agency for NASA.

This is science (?) Spatially correct, But overcomplicated. Apollo 11 Landing Site Map compiled by G. Schaber, R. Batson, and T. Hait, August 1969 that was presented to President Richard Nixon; USGS photograph P854c, F27042. USGS Open-File Report 2005-1190, Figure 064. - ID. Project Apollo (1960-1973) 064 - pap00064 - U.S. Geological Survey





Same as above, with more annotation. Traverse Map, Figure 3-16 from the Apollo 11 Preliminary Science Report

Welcome to 21st-century infographics! Thomas Schwagmeier has re-drafted a high-resolution version.


Now this is art. At the suggestion of Joe O’Dea, Thomas Schwagmeier has created an overlay of his Apollo 11 traverse diagram on a football (soccer) pitch. Spatially correct, not less complicated and still visually effective (but not very scientific). Size context is given, Lunar context is lost, however. So this may be more art than science. Designed for international audience.
Oops... Americans don't know how large a football field is... so there is a need for a localized version for the American audience. The same problem arises when spacecraft images are compared to coutry/state contours. 
Thomas Schwagmeier used a detail from the 5 November 2011 LROC image taken from 25-km altitude to revise his Apollo 11 traverse diagram overlayed on a baseball diamond, based on a suggestion by Eric Jones. Lunar context is now back but all annotation has disappeared.

So, nothing is good for me, but from these figures, a good one could be combined.










 

The Green Moon

NASA/GSFC/MIT/SVS map of the Moon, based on Lunar Reconnaissance Orbiter data. The map has been made at NASA Goddard Scientific Visualization Studio. This is the first time that yellowish green is used to represent the mare elevations; this gives a much warmer appearance than previously used light blue.



This one below has pale blues to green for mare; also warm, but closer to traditional colors and maria have a better contrast.

Solar System: Age of Discovery

This superbe figure (below) is from the Атлас планет земной группы и их спутников (Atlas of Terrestrial planets and their Moon) published in 1992 and produced during the previous 10 years at MIIGAiK, Moscow. This page shows the Soviet discoveries.

Meteor showers of Earth, Mars and Venus

This visualization shows the positions of observed (Earth) and predicted (Mars, Venus) meteor showers along the orbit of the planets.
Brigh colors are daytime showers, dark ones are nighttime showers; small dots represent slower meteors that are presumed to be less bright, larger dots show speedy meteoroids.

Slope gradient vegetated volcano




Slope map of HRSC-DTM mosaic superimposed on nadir mosaic (same orbits as Fig. 2). Slope inclinations of sector 5 contrasts to sectors 1 –4. The latter rises initially at steep slopes and flattens with progressive altitude. The lava plain to the north and west appears flat, and becomes rougher towards the south and the east. Numbers 1–5 refer to defined sectors. (Vertical and lateral collapse of Tharsis Tholus, Mars (2011) Platz, T.; Münn, S.; Walter, T. R.; [et al.] Earth and Planetary Science Letters, 305, 3-4)

Time series cross section of total horizontal wind speed in a 2 m diameter dust devil from the Mojave Desert in August 2004. The dust devil is moving toward the left, and the time axis that serves as a proxy for the horizontal axis is scaled to be consistent with the height axis. Note that the peak wind speedoccurs slightly outside the visible core (where there is a peak of combined radial and tangential wind speeds) and at about 4 m height in the front wall of the vortex. Note also that that high wind speeds extend almost to the ground in the back wall. After Metzger et al. [2004a]. (Balme and Greeley: DUST DEVILS ON EARTH AND MARS)
