[6af6d51] | 130 | <Para><Application>Survex</Application> is a multi-platform open-source cave surveying |
---|
[6e420ba] | 131 | package. |
---|
[d959ab2] | 132 | Version 1.2 |
---|
[6af6d51] | 133 | currently runs on UNIX, Microsoft Windows 95/NT and |
---|
[56ad6ad] | 134 | successors, and Mac OS X. |
---|
[64d37a3] | 135 | We're investigating support for various |
---|
[6e420ba] | 136 | palmtop devices. |
---|
[6af6d51] | 137 | Version 1.0 has fewer features, but also runs on DOS and RISC OS machines. |

---|
[40647f5] | 139 | |
---|
[c1573d8] | 140 | <Para>We are well aware that not everyone has access to super hardware |
---|
| 141 | - often surveying projects are run on little or no budget and any |
---|
[6af6d51] | 142 | computers used are donated. We aim to ensure that <Application>Survex</Application> is |
---|
[57a5ebb] | 143 | feasible to use on low-spec machines. Obviously it won't be as |
---|
| 144 | responsive, but we intend it to be usable. |
---|
| 145 | Please help us to achieve this by giving us some feedback |
---|
[6af6d51] | 146 | if you use <Application>Survex</Application> on a slow machine.</Para> |

[c1eff09] | 149 | quickly and has a very effective, real-time cave viewer which allows |
---|
[0706076] | 150 | you to rotate, zoom, and pan the cave using mouse or keyboard. We have |
---|
[6af6d51] | 151 | tested it extensively using <Acronym>CUCC</Acronym> and <Acronym>ARGE</Acronym>'s surveys of the caves |
---|
[a3f8737] | 152 | under the Loser Plateau in Austria (over 22,000 survey legs, and over |

| 153 | 120km of underground survey data). This can all be processed in around |

[ff003b3] | 699 | <Para>Survey data is entered in the form of text files. You can use any |
---|
| 700 | text editor you like for this, so long as it has the capability of |
---|
[1a50c3c] | 701 | writing a plain ASCII text file. The data format is very flexible; |
---|
[eb48e2b] | 702 | unlike some other cave surveying software, Survex does not require |
---|
| 703 | survey legs to be rearranged to suit the computer, and the ordering |
---|
| 704 | of instrument readings on each line is fully specifiable. So you can enter |
---|
[1a50c3c] | 705 | your data much as it appears on the survey notes, which is important |
---|
[eb48e2b] | 706 | in reducing the opportunities for transcription errors. |

---|
| 708 | |

[191536f] | 709 | <Para> |
---|
[a7e3295] | 710 | Also all the special characters are user-definable - for example, |
---|
[191536f] | 711 | the separators can be spaces and tabs, or commas (e.g. when exporting from a |
---|
| 712 | spreadsheet), etc; the decimal point can be a slash (for clarity), a comma |
---|
[1a50c3c] | 713 | (as used in continental Europe), or anything else you care to choose. |
---|
| 714 | This flexibility |
---|
[ff003b3] | 715 | means that it should be possible to read in data from almost any sort of |

---|
[c1573d8] | 721 | read it all in before determining how it is connected. You can also use the |

[c1573d8] | 731 | will process the dreamtime file/section of Kaninchenhöhle. To |

[1a50c3c] | 732 | help you out, if all legs in a survey are connected to one another |

| 772 | So point 6 in the entrance survey of Kaninchenhöhle |

---|
| 1185 | What I mean (though failed to express very well) is that a dataset without |
---|
| 1186 | this information isn't the same dataset (in general anyway). For example: |
---|
| 1187 | |
---|
| 1188 | A1 a2 10.32 140 -05 |
---|
| 1189 | a2 a3 4.91 041 -01 |
---|
| 1190 | a1 a3 7.01 206 02 |
---|
| 1191 | |
---|
| 1192 | is either a traverse of 3 legs or a (probably badly misclosed) loop. If |
---|
| 1193 | these names are on the original survey notes, the surveyors ought to say |
---|
| 1194 | whether "A1" is the same as "a1" (although the usual case for using this |
---|
| 1195 | feature is probably for importing data from elsewhere). Similarly for |
---|
| 1196 | truncation. Whether a clino of +/-90 degrees (or +/-100 grad, etc) is |
---|
| 1197 | interpreted as a plumb is something that should have been noted in the cave |
---|
| 1198 | (unless it's implicit because it's standard practice for a survey project). |
---|
| 1199 | |
---|
| 1200 | It's a similar issue to calibration data in many ways. You can argue it's |
---|
| 1201 | not part of "the survey", but without it the survey won't be the same shape, |
---|
| 1202 | and it's not useful to process the same survey with different settings for |
---|
| 1203 | compass calibration or name case sensitivity. |
---|
| 1204 | |
---|
| 1205 | >Clearly that is unhelpfully strict, but it is |
---|
| 1206 | >important to be semantically clear about what is 'data' and what is 'commands |
---|
| 1207 | >or meta-data' which describe what to do with/how to interpret that data. |
---|
| 1208 | |
---|
| 1209 | Think of the lines starting with a "*" as "command or meta-data". |
---|
| 1210 | |
---|
[3d5fb53] | 1211 | >The most-correct solution to this is (I believe) Martin Heller's idea about |
---|
[c1573d8] | 1212 | >including 'rules' in the datastream, but that's too big a subject for right |
---|
| 1213 | >now. |
---|
| 1214 | > |
---|
| 1215 | >The reason '-C' was made into a command-line option, was that it made very |
---|

---|
[375f7f6] | 1217 | >you suddenly tell cavern to become case-sensitive halfway through a run? |
---|
[c1573d8] | 1218 | |
---|
| 1219 | -C has always had 3 settings - "leave case alone", "force to lower", and |
---|
| 1220 | "force to upper". It doesn't really mean "case sensitivity" but rather |
---|
| 1221 | something like "case processing". So you can usefully change it during a |
---|
| 1222 | run. So if my dataset treats "NoTableChamber" (so named because it was |
---|
| 1223 | lacking in furniture) as different from "NotableChamber" (which was notable |
---|
| 1224 | for other reasons) I can process it with a dataset from someone else which |
---|
| 1225 | needs to be treated as case insensitive like so: |
---|
| 1226 | |
---|
| 1227 | *begin my_cave |
---|
| 1228 | *include my_dataset |
---|
| 1229 | *end my_cave |
---|
| 1230 | |
---|
| 1231 | *equate my_cave.NoTableChamber.14 your_cave.linkpassage.13 |
---|
| 1232 | |
---|
| 1233 | *begin your_cave |
---|
| 1234 | *case tolower |
---|
| 1235 | *include your_dataset |
---|
| 1236 | *end your_cave |
---|
| 1237 | |
---|
| 1238 | You may be thinking of -U<n>, which used to mean "only compare the first n |
---|
| 1239 | characters of station names", but that doesn't allow arbitrary datasets to |
---|
| 1240 | be processed together. |
---|
| 1241 | |
---|
| 1242 | So we changed it to mean "truncate station names to n characters", and |
---|
| 1243 | allowed it to be changed at any point, rather than being set once for the |
---|
| 1244 | whole run. |

| 1380 | |
---|
[ad5bd05] | 1381 | <Para> |
---|
| 1382 | By default, Survex works in an unspecified coordinate system (and this was the |
---|
| 1383 | only option before *cs was added). However, it's useful for coordinate system |
---|
| 1384 | which the processed survey data is in to be specified if you want to use the |
---|
| 1385 | processed data in ways which required knowing the coordinate system (such as |
---|
| 1386 | exporting a list of entrances for use in a GPS). You can now do this by using |
---|
| 1387 | "*cs out". |
---|
| 1388 | </Para> |
---|
| 1389 | |
---|
| 1390 | <Para> |
---|
| 1391 | It is also useful to be able to take coordinates for fixed points in whatever |
---|
| 1392 | coordinate system you receive them in and put them directly into Survex, rather |
---|
| 1393 | than having to convert with an external tool. For example, you may have your |
---|
| 1394 | GPS set to show coordinates in UTM with the WGS84 datum, even though you want |
---|
| 1395 | the processed data to be in some local coordinate system. And someone else |
---|
| 1396 | may provide GPS coordinates in yet another coordinate system. You just need |
---|
| 1397 | to set the appropriate coordinate system with "*cs" before each group of "*fix" |
---|
| 1398 | commands in a particular coordinate system. |
---|
| 1399 | </Para> |
---|
| 1400 | |
---|
| 1401 | <Para> |
---|
| 1402 | If you're going to make use of "*cs", then the coordinate system must be |
---|
| 1403 | specified for everything, so a coordinate system must be in effect for all |
---|
| 1404 | "*fix" commands, and you must set the output coordinate system before any |
---|
| 1405 | points are fixed. |
---|
| 1406 | </Para> |
---|
| 1407 | |
---|
| 1408 | <Para> |
---|
| 1409 | Also, if "*cs" is in use, then you can't omit the coordinates in a "*fix" |
---|
| 1410 | command, and a fixed point won't be invented if none exists. |
---|
| 1411 | </Para> |
---|
| 1412 | |
---|
| 1413 | <Para> |
---|
| 1414 | If you use "*cs out" more than once, the second and subsequent commands are |
---|
| 1415 | silently ignored - this makes it possible to combine two datasets with |
---|
| 1416 | different "*cs out" settings without having to modify either of them. |
---|
| 1417 | </Para> |
---|
| 1418 | |
---|
| 1419 | <Para> |
---|
| 1420 | Something to be aware of with "*cs" is that altitudes are currently assumed to |
---|
| 1421 | be "height above the ellipsoid", whereas GPS units typically give you "height |
---|
| 1422 | above sea level", or more accurately "height above a particular geoid". This |
---|
| 1423 | is something we're looking at how best to address, but you shouldn't need to |
---|
| 1424 | worry about it if your fixed points are in the same coordinate system as your |
---|
| 1425 | output, or if they all use the same ellipsoid. For a more detailed discussion |
---|
| 1426 | of this, please see: http://expo.survex.com/handbook/survey/coord.htm |

| 2076 | standard file of benchmarks, some of which won't be used. |
---|
| 2077 | In this sort of situation, specify "REFERENCE" after the station name |

[e74904e] | 2081 | <Note><Para> |

[fe16ba3] | 2082 | X is Easting, Y is Northing, and Z is altitude. This convention was chosen |
---|
| 2083 | since on a map, the horizontal (X) axis is usually East, and the vertical |
---|
| 2084 | axis (Y) North. The choice of altitude (rather than depth) for Z is taken |
---|
| 2085 | from surface maps, and makes for less confusion when dealing with cave |
---|
| 2086 | systems with more than one entrance. It also gives a right-handed |

| 2087 | set of axes. |

| 2521 | <standard deviation> must include units and thus is typically |

[63dc4eb] | 2522 | "0.05 metres", or "0.02 degrees". See *units below for full list |

[6048971] | 2526 | <!-- FIXME mention central limit theorem --> |
---|
[40647f5] | 2527 | <Para> |
---|
[6048971] | 2528 | To utilise this command fully you need to understand what a |
---|
| 2529 | <emphasis>standard deviation</emphasis> is. |
---|
| 2530 | It gives a value to the 'spread' of the errors |
---|
[c1573d8] | 2531 | in a measurement. Assuming that these are normally distributed |
---|
[770157e] | 2532 | we can say that 95.44% of the actual lengths will fall within two |
---|
[40647f5] | 2533 | standard deviations of the measured length. i.e. a tape SD of |
---|
[770157e] | 2534 | 0.25 metres means that the actual length of a tape measurement |
---|
| 2535 | is within + or - 0.5 metres of the recorded value 95.44% of the time. |
---|
[40647f5] | 2536 | So if the measurement is 7.34m then the actual length is very |
---|
[6048971] | 2537 | likely to be between 6.84m and 7.84m. This example corresponds |
---|
[40647f5] | 2538 | to BCRA grade 3. Note that this is just one interpretation of |
---|
[770157e] | 2539 | the BCRA standard, taking the permitted error values as 2SD 95.44% |
---|
[40647f5] | 2540 | confidence limits. If you want to take the readings as being some |
---|
[6048971] | 2541 | other limit (e.g. 1SD = 68.26%) then you will need to change the BCRA3 |
---|
[c1573d8] | 2542 | and BCRA5 files accordingly. This issue is explored in more |
---|
[40647f5] | 2543 | detail in various surveying articles. |

[40647f5] | 3001 | <Para> |

[6af6d51] | 3002 | <Application>Survex</Application> places few restrictions on station naming (see "Survey |

| 3004 | as they were in the original survey notes. Although not apparent from |

| 3005 | this example, there is no requirement for each leg to connect to an |
---|
[6af6d51] | 3006 | existing station. <Application>Survex</Application> can accept data in any order, and will |

[40647f5] | 3016 | <Para> |

| 3017 | Most caves will take more than just one survey trip to map. Commonly |

[5b5a89f] | 3255 | <Para>This is done by using the *SD command to specify the appropriate |

| 3260 | <Para>The best approach for a radiolocation where the underground station |
---|
| 3261 | is vertically below the surface station is to represent it as a |
---|
| 3262 | plumbed leg, giving suitable SDs for the length and plumb angle. The |
---|
| 3263 | horizontal positioning of this is generally quite accurate, but the |
---|
| 3264 | vertical positioning may be much less well known. E.g: we have a |
---|
| 3265 | radiolocation of about 50m depth +/- 20m and horizontal accuracy of |
---|
| 3266 | +/- 8m. Over 50m the +/-8m is equivalent to an angle of 9 degrees, so |
---|
| 3267 | that is the expected plumb error. 20m is the expected error in the |
---|
[e74904e] | 3268 | length. To get the equivalent SD we assume that 99.74% of readings will |
---|
[5b5a89f] | 3269 | be within 3 standard deviations of the error value. Thus we divide the |
