Survex 3d files can be downloaded for certain caves and areas. The Aven viewer is required and this can be downloaded from the Survex site. The version currently used is 1.4.5 (at May 2024). An alternative to the Aven viewer is the Loch viewer found in the Therion package. Although this doesn't show station numbers, it does display cave line and walls in stereo when viewed though red/cyan glasses.
PDF files have also been produced for many surveys. The Foxit pdf reader can be downloaded from here.
PNG files have (in 2006) started to be produced from Tunnel. These can be viewed in a browser window.
SVG files can also be viewed directly in a browser window.

The cave descriptions on the Matienzo Caves web site would not be possible without all the "anonymous" log book contributors and the major input from the following contributors, either in writing cave descriptions, drawing original cave surveys, or contributing photographs / videos:

Line diagrams are drawn by Pete Smith (PS).

Most of the surveys have been redrawn by Juan Corrin (JC) using Acorn !Draw, Corel Draw, occasionally Tunnel and more recently InkScape, CaveRenderPro and Affinity Designer 2.
At the risk of leaving people out, the following cavers are those most involved (2010 - now) in drawing and revising final versions of surveys - Diane Arthurs, Simon Cornhill, Juan Corrin, Phil Papard and Pete Smith.
The following cavers have provided original survey drawings or completed surveys (usually pdf files) :

Paul Fretwell (PF) has started the resurvey and redrawing of the Four Valleys System first using Tunnel then Therion. Phil Papard has combined the surveys of the Cubija (North Vega) System using Corel Draw.

A number of descriptions have been modified from previous publications and the primary authors of those include John Yeadon, Juan Carlos Fernández Gutiérrez and Peter Smith. Dozens more people have contributed to the text by writing up activities in the log books. The total of these contributions has given a particularly complete picture about the sites of speleological interest around Matienzo and their exploration since the mid sixties.
[Since the early 1990's greater contact has occurred between British cavers and others working in surrounding areas - (Tortosa, FCME, Lobetum, SEAD, La Cambera, ADEMCO, Jesus, Alix, etc). And also the contributions of other nationalities, eg French. This needs expanding upon].
