2017 Tapia Conference

Change from Cartesian to Speleologist Coordinates


Presenter: Gustavo Jose Rivera Roca (University of Puerto Rico- Arecibo)

The caveGEOmap program implement codes in Matlab® to create cave maps in 2-D and 3-D for caves that contain more than one path/ramification. Speleologists need maps to explore and characterize caves. We are creating a cost efficiency and friendly user software to the scientific community. The data would be represented in speleologist’s coordinates: latitude, azimuth and length. To collect data we use a digital laser distance measurer, clinometer and a compass to obtain the measurements of the cave. My contribution to caveGEOmap was to create an algorithm that allows the input of data in Cartesian coordinates and change it into the speleologist coordinate system, which is used in the field and as traditional input for the software. This conversion software serves as a tool to visualize fictitious caves and be able to perform the internal adjustments and necessary coding changes to caveGEOmap. Every user can have the advantage of a 2-D and 3-D graphic of the cave and could be more secure of his adventure. It Also can help scientist in research and investigations with our maps in the Northern Karst region in Puerto Rico. This modern cave cartography method could represent a new low cost way to create maps.
