-Much of the PocketTopo information below on station numbering and survey legs seems to be needlessly complicated,​ or just wrong, so it will probably get deleted in due course. Changes will probably be made sporadically. ​ If you have any changes you'd like to see, let me know via the forum. ​ \\ +

 This way the centrelines of other surveys remain visible and only the sketches of the currently open file can be seen (reduces confusion). ​ It also reduces the chance of accidentally changing the data from a previous days survey.\\ This way the centrelines of other surveys remain visible and only the sketches of the currently open file can be seen (reduces confusion). ​ It also reduces the chance of accidentally changing the data from a previous days survey.\\

-The definition of '​series'​ in the next two sections is quite restrictive,​ and in practice I ignore it, without I think, many consequences. 
-  
-==PocketTopo Station Numbering== 
-  *The logic of PocketTopo numbering follows the so-called "​Toporobot method"​. You may find the description of this method here:\\ 
-        *[[http://​tinyurl.com/​yln45n8|history of Toporobot and several recomendations]]\\ 
-        *[[http://​tinyurl.com/​yefkbtr|Toporobot Method French version]]\\ 
-        *[[http://​tinyurl.com/​yc9x3df|Toporobot Method German version]]\\ 
-        *[[http://​tinyurl.com/​yhsjpwr|Google Translated EN version -> Manual -> Toporobot method]]\\ 
-        *The cave survey is divided into a number of "​series",​ one or more for each survey trip. Each series has its own number beginning 1, 2, //m//... Each series starts with 0 and continues 1, 2, 3, ... It means, the first station of first series has number 1.0, then 1.1, 1.2, 1.3 etc, the second series 2.0 and then 2.1, 2.2, 2.3, 2.4 and so on.  
-        *The station label //m//.0 is only used when starting at a previously unsurveyed location. ​ If you are starting from an existing station, you use that stations name, then the next station is //m//.1, where //m// is the number of the next series. 
-        *Each series needs to be stored in it's own separate file. ie You use Menu.File.New when you need to start a new series. 
- 
-==PocketTopo Survey Loops and Connections== 
-I break these rules (for numbering and series) regularly, and don't seem to suffer too many consequences. ​ PocketTopo is getting better (1.36) but is perhaps helpful to know where it has come from. 
- 
-  *The series MUST NOT cross itself. This means that loops can ONLY be formed at the start or end of a series. ​ In PocketTopo you must divide surveys in a similar way, and start a new file for each series.\\  ​ 
- 
-  *The series are linked at start or end points. That is, each series can ONLY attach to the start or end point of a different series, or to somewhere in the middle of itself. A series can also start or end without attaching to another series (but must be attached at one end if there are more than one series in the cave, unless of course you know the co-ordinates for a point in the '​disconnected'​ series). 
- 
-  *This means that each survey station has one and only one number/​name/​label as far as PocketTopo is concerned (this can be relaxed once you get the data into Therion).

-{{:​paperless:​toporsurveyloops.png?​450|How to join up all the survey '​series'​}} 
- 
-This is why series 4 (yellow) ends when it gets to station 1.4, and continues as series 5.  Similarly for series 7 (green) to series 12, and series 8 (purple) to series 9. 
- 
-As mentioned above, the rules above on station numbering, loops and connections seem to be overly restrictive and in my experience PocketTopo works just fine 98% of the time when i ignore them.
