MATIENZO CAVES PROJECT
Caves with Survey Issues

Simon Cornhill has suggested that it would be useful to recreate cave centre lines from surveys where the original data has been lost.
• A search through 5000+ online site descriptions has brought to light 334 sites with a survey but no centre line. These range through full plan and elevation, to plans without a N arrow, to sketches. Investigation revealed that only a few of these surveys were suitable for the (armchair) Survex centre line creation process but many sites would benefit from a complete resurvey.
• So the original suggestion has grown to include a number of survey possibilities which are detailed by clicking on the headers below. The final header shows the table of identified caves which have a survey but no centre line along with codes which describe the survey and/or possible action. The whole table can be filtered.
• Of course, there are many sites which have neither a survey nor a centre line. These are not included here.
• Many sites have both a centre line and a drawn survey, but there is no LRUD data on the centre line. These are also not shown below.

Many paper survey notes are archived in Matienzo. It may be best to see these before starting any centre line construction. The survey may also have name(s) to consult as well. Original surveyors may also be holding survey notes or files. Filter with 'mm'.

A centre line cannot be constructed off these surveys as there is no indication of the north direction.

Filter with 'mr' to pick out sites for resurveying.
Many surveys may be just a plan or elevation so are unsuitable to go through the Survex reconstruction as there is no clues for altitude changes or shaft shape. Other 'surveys' may be a sketch with no North.
Such sites may be suitable for a resurvey although some may be classed as trivial. The length / depth on the table provides an indication; the shorter ones may be digs with potential. A number of these sites may be outside the current permit area and may not be 'ours' to (re)survey. Others may have going leads.
Some of the sites may be suitable for survey training purposes and some suitable for future cloud-point surveys using, e.g. Caveatron.
• Anyone wanting to resurvey or survey a particular site should discuss with Phil Papard to avoid duplication.


Filter with 'mrr' to show those sites which have recently been resurveyed.

Sketches are most unlikely to be suitable for centre line construction so the site will either be small or require surveying. Filtering with 'ms' will pick out the sketches

Some of these surveys are decades old but, nevertheless, original survey material may still be available from individuals or caving groups. The list is not exhaustive. Material may also be stored in the Matienzo archive, especially the earlier numbers, before we went 'all digital'.

   Filtering sites with a * will show those where a centre line could be reconstructed from the available survey. There may be additional codes which should be considered.
    There may also be sketches without a N direction that could be suitable if they are shown relative to a road or other feature that can be seen on a map.
• There may be further information hidden away in the logbooks. They can be searched.
• Anybody is very welcome to take on one or more caves - but please inform Juan juancorrin[at]matienzo.org.uk which you are claiming before you start.


    At the heart of the process is Patrick Warren's extension to the Inkscape drawing program - a piece of software that allows the user to click on a scanned survey or file to produce survey stations and eventually a complete svx file.

• Some knowledge of using Inkscape is presumed although there are (slightly out-dated) help files to get you started.
Inkscape : Download Version 1.0.2 and install it.
• Patrick Warren's Extension to Inkscape in a zip file: v2.1 for Inkscape 1.0 : Read Me file (also in the zip file) in HTML or PDF
  - After unzipping the folder, follow the instructions in the ReadMe file to put the extension into the correct folder (2 files to copy/move). For Windows 10, the folder "%APPDATA%\inkscape\extensions\" is usually
"C:\Users\Your user folder\AppData\Roaming\inkscape\extensions\"
  - The ReadMe file contains a suggested work flow.

• Patrick would like suggestions for improvements to the Extension and/or the documentation. patrickbwarren[at]gmail.com
• With the information from the old surveys, as well as producing a centre line, it may also be possible to add left, right, up, down data to the stations. A simple centre line is better than nothing, as long as reasonable Z data is available or can be deduced.
• It may be that, to produce a reasonable 3d file from the svx, extra legs have to be introduced, e.g. into originally unsurveyed rifts or up slopes, etc. Any new length calculation should take a common sense approach and possibly exclude such legs between *FLAGS SPLAYS and *FLAGS NOT SPLAYS.
• Each Survex file should be named nnnn-RCN.svx where nnnn is the site number and RCN indicates that the svx file is reconstructed both when viewed alone and within area or regional groups. "*BEGIN nnnn-RCN" should also be used in the svx file.


Filtering with 'svx' will pick out the sites which have gone through the recent process of having a centre line produced using Patrick's Warren's Extension for Inkscape.

• The information in the table below is updated as people claim a site or new information comes to light and as centre lines are generated.
Each new centre line is added to the Survex / Aven area map to give an increasingly comprehensive picture.
