What is .SVX file extension?
ASCII text file created in the Survex format, a raw data format used for capturing cave surveying information; contains "centreline" data which includes the logged locations in the cave; used for mapping caves, exploring relationships between cave systems, and creating 3D visualizations.
SVX files may also contain instructions for including other files, data calibration, and survey stations.
Survex includes a program called "cavern" that reads SVX files and produces .3D files. The 3D files can be opened in another included program, "Aven," for 3D visualization.
