Crusta is a virtual globe developed by a computer science graduate student working closely with students in geology who deﬁned the needs, tested the code, and suggested additional features. Crusta combines:
Using Crusta, a student researcher can easily import sub-meter resolution DEM or imagery for arbitrary locations on the globe. Dynamic manipulation of the visualization (illumination, vertical exaggeration, color mapping, iso-lines) support explorative discovery of key surface features and a clear understanding of their three-dimensional embedding. Features can be directly mapped on the virtual landscape. This capability greatly improves the conﬁdence and localization of mapped features.
Crusta is still being actively developed with constant changes to the feature-set and the robustness of the implementations. To keep up to date, we recommend you get involved!
Get involved with Crusta! There are currently three primary parts to doing so:
Crusta was critical to the success of the Haiti Earthquake Team. It enabled the students to identify and label the fault and other geologic features. It has been used by student researchers to investigate settings where it would be difﬁcult to impossible to travel, for logistical or safety reasons.
In the study of the earthquake in Baja-California students were able to visually investigate the high-resolution (~3cm/pixel) topography model from their own terrestrial LiDAR scans in the context aerial and orbital data.
Crusta has been used to investigate potential landing sites for the next Mars rover.
