The best path of illustrating the Cerberus platform method is to present a short example. Here we see River Meanders in Eberswalde Delta (PSP_001534_1560, HiRise) which our players had to cartograph in order to prove te concept. Click here for some results.
What to do
On the map our players had to mark a variety of features of what they could recognize. An extensive interactive help function, bennefiting the e-learning, provided our players with what to look for in order to mark the features in a correct way. Marking features went with a predefined toolset and a single tool which could be used to mark interesting object textually. Here an example of how a portion of the map looks like once a player had conducted its work. Note each type of marking has its own icon and a score. The higher the score the better you perform.
Cerberus will bring an interactive solution where to insert the to be mapped photographs. These photographs will be uploaded along with its planetary coordinates and automattically inserted into te game. Specific requirements of the photograph provider can of course be used in the game.
The first feature, "Aeolian Processes", covers the study of landforms formed by wind. The players were asked if they could find two different types of these surface evolutionary processes. These are Transverse Aeolian Ridges (TARs) and Honeycomb bedforms.
TARs describe three levels of linear wind erosion which is in the form of ripples, dunes and draas (Zimbelman, 2009). Honeycomb bedforms also come in three levels, but are not linearly shaped (Bridges et al., 2010).
The second feature, "Gullies and River Meanders", are places on mars where there could have been water in the past and thus is caused by water erosion (Berman, 2010, McEwen, 2006; NWT, 2010).
The third feature, "Layers", is about vertically ordered ground. Layers are often created by sediments which have set down on the ground by water, dust storms, volcanic eruptions or crater-impacts (Grant et al., 2010; Ross, 2009).
The fourth feature, "Anomalies", is different from the other three features because this one is not specifically defined. If the player recognized something strange which could not be marked as any other feature it could still be interesting to mention. This feature could for example be about the marking of strange colored mountains, strange shapes or Mars landers like the Phoenix (Bridges, 2006).
