[6af6d51] | 129 | <Para><Application>Survex</Application> is a multi-platform open-source cave surveying |
---|
[6e420ba] | 130 | package. |
---|
[aa3ed76] | 131 | Version 1.2 runs on UNIX, Microsoft Windows, and Mac OS X. |

| 132 | We're investigating support for phones and tablets. |

[40647f5] | 134 | |
---|
[c1573d8] | 135 | <Para>We are well aware that not everyone has access to super hardware |
---|
| 136 | - often surveying projects are run on little or no budget and any |
---|
[6af6d51] | 137 | computers used are donated. We aim to ensure that <Application>Survex</Application> is |
---|
[57a5ebb] | 138 | feasible to use on low-spec machines. Obviously it won't be as |
---|
| 139 | responsive, but we intend it to be usable. |
---|
| 140 | Please help us to achieve this by giving us some feedback |
---|
[6af6d51] | 141 | if you use <Application>Survex</Application> on a slow machine.</Para> |

[6aef4f1] | 142 | |

[6af6d51] | 143 | <Para><Application>Survex</Application> is capable of processing extremely complex caves very |

[c1eff09] | 144 | quickly and has a very effective, real-time cave viewer which allows |
---|
[0706076] | 145 | you to rotate, zoom, and pan the cave using mouse or keyboard. We have |
---|
[6af6d51] | 146 | tested it extensively using <Acronym>CUCC</Acronym> and <Acronym>ARGE</Acronym>'s surveys of the caves |
---|
[1352bb9] | 147 | under the Loser Plateau in Austria (over 25,000 survey legs, and over |

| 148 | 140km of underground survey data). This can all be processed in around |

[ff003b3] | 671 | <Para>Survey data is entered in the form of text files. You can use any |
---|
| 672 | text editor you like for this, so long as it has the capability of |
---|
[1a50c3c] | 673 | writing a plain ASCII text file. The data format is very flexible; |
---|
[eb48e2b] | 674 | unlike some other cave surveying software, Survex does not require |
---|
| 675 | survey legs to be rearranged to suit the computer, and the ordering |
---|
| 676 | of instrument readings on each line is fully specifiable. So you can enter |
---|
[1a50c3c] | 677 | your data much as it appears on the survey notes, which is important |
---|
[eb48e2b] | 678 | in reducing the opportunities for transcription errors. |

| 680 | |

[191536f] | 681 | <Para> |
---|
[a7e3295] | 682 | Also all the special characters are user-definable - for example, |
---|
[191536f] | 683 | the separators can be spaces and tabs, or commas (e.g. when exporting from a |
---|
| 684 | spreadsheet), etc; the decimal point can be a slash (for clarity), a comma |
---|
[1a50c3c] | 685 | (as used in continental Europe), or anything else you care to choose. |
---|
| 686 | This flexibility |
---|
[ff003b3] | 687 | means that it should be possible to read in data from almost any sort of |

[c1573d8] | 693 | read it all in before determining how it is connected. You can also use the |

[3d5fb53] | 699 | <Para>The usual arrangement is to have one file which lists all the others |

[1a50c3c] | 704 | help you out, if all legs in a survey are connected to one another |

[6af6d51] | 741 | <Para><Application>Survex</Application> has a powerful system for naming stations. It |

---|
| 744 | So point 6 in the entrance survey of Kaninchenhöhle |

[a4458fd5] | 745 | (cave number 161) is referred to as: 161.entrance.6 |

| 748 | <Para>This seems a natural way to refer to station names. It also |

[513935e] | 1073 | *calibrate is used to specify instrument calibrations, via a zero error |

[513935e] | 1088 | You need to be careful about the sign of the ZeroError. Survex follows |

| 1089 | the convention used with scientific instruments - the ZeroError is what |
---|
| 1090 | the instrument reads when measuring a reading which should be zero. So |
---|
| 1091 | for example, if your tape measure has the end missing, and you are using the |
---|
| 1092 | 30cm mark to take all measurements from, then a zero distance would be measured |
---|
| 1093 | as 30cm and you would correct this with: |

[88569fe] | 1108 | <Para> |
---|
| 1109 | In the first form in the synopsis above, the zero error is measured by the |
---|
| 1110 | instrument itself (e.g. reading off the number where a truncated tape now ends) |
---|
| 1111 | and any scale factor specified applies to it, like so: |
---|
| 1112 | </Para> |
---|
| 1113 | |
---|
| 1114 | <Para> |
---|
| 1115 | Value = ( Reading - ZeroError ) * Scale (Scale defaults to 1.0) |
---|
| 1116 | </Para> |
---|
| 1117 | |
---|
| 1118 | <Para> |
---|
| 1119 | In the second form above (supported since Survex 1.2.21), the zero error has |
---|
| 1120 | been measured externally (e.g. measuring how much too long your tape is with |
---|
| 1121 | a ruler) - the units of the zero error are explicitly specified and any scale |
---|
| 1122 | factor isn't applied to it: |
---|
| 1123 | </Para> |
---|
| 1124 | |
---|
| 1125 | <Para> |
---|
| 1126 | Value = ( Reading * Scale ) - ZeroError (Scale defaults to 1.0) |
---|
| 1127 | </Para> |
---|
| 1128 | |
---|
| 1129 | <Para> |
---|
| 1130 | If the scale factor is 1.0, then the two forms are equivalent, though they |
---|
[e1888e5] | 1131 | still allow you to differentiate between how the zero error has been determined. |

[513935e] | 1135 | With older Survex versions, you would specify the magnetic declination |
---|
| 1136 | (difference between True North and Magnetic North) by using *calibrate |
---|
| 1137 | declination to set an explicit value (with no scale factor allowed). Since |
---|
| 1138 | Survex 1.2.22, it's recommended to instead use the new *declination command |
---|
| 1139 | instead - see the documentation of that command for more details. |

[c1573d8] | 1207 | |
---|
| 1208 | What I mean (though failed to express very well) is that a dataset without |
---|
| 1209 | this information isn't the same dataset (in general anyway). For example: |
---|
| 1210 | |
---|
| 1211 | A1 a2 10.32 140 -05 |
---|
| 1212 | a2 a3 4.91 041 -01 |
---|
| 1213 | a1 a3 7.01 206 02 |
---|
| 1214 | |
---|
| 1215 | is either a traverse of 3 legs or a (probably badly misclosed) loop. If |
---|
| 1216 | these names are on the original survey notes, the surveyors ought to say |
---|
| 1217 | whether "A1" is the same as "a1" (although the usual case for using this |
---|
| 1218 | feature is probably for importing data from elsewhere). Similarly for |
---|
| 1219 | truncation. Whether a clino of +/-90 degrees (or +/-100 grad, etc) is |
---|
| 1220 | interpreted as a plumb is something that should have been noted in the cave |
---|
| 1221 | (unless it's implicit because it's standard practice for a survey project). |
---|
| 1222 | |
---|
| 1223 | It's a similar issue to calibration data in many ways. You can argue it's |
---|
| 1224 | not part of "the survey", but without it the survey won't be the same shape, |
---|
| 1225 | and it's not useful to process the same survey with different settings for |
---|
| 1226 | compass calibration or name case sensitivity. |
---|
| 1227 | |
---|
| 1228 | >Clearly that is unhelpfully strict, but it is |
---|
| 1229 | >important to be semantically clear about what is 'data' and what is 'commands |
---|
| 1230 | >or meta-data' which describe what to do with/how to interpret that data. |
---|
| 1231 | |
---|
| 1232 | Think of the lines starting with a "*" as "command or meta-data". |
---|
| 1233 | |
---|
[3d5fb53] | 1234 | >The most-correct solution to this is (I believe) Martin Heller's idea about |
---|
[c1573d8] | 1235 | >including 'rules' in the datastream, but that's too big a subject for right |
---|
| 1236 | >now. |
---|
| 1237 | > |
---|
| 1238 | >The reason '-C' was made into a command-line option, was that it made very |
---|
| 1239 | >little sense to change it part way though a dataset. What exactly happens if |
---|
[375f7f6] | 1240 | >you suddenly tell cavern to become case-sensitive halfway through a run? |
---|
[c1573d8] | 1241 | |
---|
| 1242 | -C has always had 3 settings - "leave case alone", "force to lower", and |
---|
| 1243 | "force to upper". It doesn't really mean "case sensitivity" but rather |
---|
| 1244 | something like "case processing". So you can usefully change it during a |
---|
| 1245 | run. So if my dataset treats "NoTableChamber" (so named because it was |
---|
| 1246 | lacking in furniture) as different from "NotableChamber" (which was notable |
---|
| 1247 | for other reasons) I can process it with a dataset from someone else which |
---|
| 1248 | needs to be treated as case insensitive like so: |
---|
| 1249 | |
---|
| 1250 | *begin my_cave |
---|
| 1251 | *include my_dataset |
---|
| 1252 | *end my_cave |
---|
| 1253 | |
---|
| 1254 | *equate my_cave.NoTableChamber.14 your_cave.linkpassage.13 |
---|
| 1255 | |
---|
| 1256 | *begin your_cave |
---|
| 1257 | *case tolower |
---|
| 1258 | *include your_dataset |
---|
| 1259 | *end your_cave |
---|
| 1260 | |
---|
| 1261 | You may be thinking of -U<n>, which used to mean "only compare the first n |
---|
| 1262 | characters of station names", but that doesn't allow arbitrary datasets to |
---|
| 1263 | be processed together. |
---|
| 1264 | |
---|
| 1265 | So we changed it to mean "truncate station names to n characters", and |
---|
| 1266 | allowed it to be changed at any point, rather than being set once for the |
---|
| 1267 | whole run. |

---|
[ad5bd05] | 1409 | <Para> |
---|
| 1410 | By default, Survex works in an unspecified coordinate system (and this was the |
---|
| 1411 | only option before *cs was added). However, it's useful for coordinate system |
---|
| 1412 | which the processed survey data is in to be specified if you want to use the |
---|
| 1413 | processed data in ways which required knowing the coordinate system (such as |
---|
| 1414 | exporting a list of entrances for use in a GPS). You can now do this by using |
---|
| 1415 | "*cs out". |
---|
| 1416 | </Para> |
---|
| 1417 | |
---|
| 1418 | <Para> |
---|
| 1419 | It is also useful to be able to take coordinates for fixed points in whatever |
---|
| 1420 | coordinate system you receive them in and put them directly into Survex, rather |
---|
| 1421 | than having to convert with an external tool. For example, you may have your |
---|
| 1422 | GPS set to show coordinates in UTM with the WGS84 datum, even though you want |
---|
| 1423 | the processed data to be in some local coordinate system. And someone else |
---|
| 1424 | may provide GPS coordinates in yet another coordinate system. You just need |
---|
| 1425 | to set the appropriate coordinate system with "*cs" before each group of "*fix" |
---|
| 1426 | commands in a particular coordinate system. |
---|
| 1427 | </Para> |
---|
| 1428 | |
---|
| 1429 | <Para> |
---|
| 1430 | If you're going to make use of "*cs", then the coordinate system must be |
---|
| 1431 | specified for everything, so a coordinate system must be in effect for all |
---|
| 1432 | "*fix" commands, and you must set the output coordinate system before any |
---|
| 1433 | points are fixed. |
---|
| 1434 | </Para> |
---|
| 1435 | |
---|
| 1436 | <Para> |
---|
| 1437 | Also, if "*cs" is in use, then you can't omit the coordinates in a "*fix" |
---|
| 1438 | command, and a fixed point won't be invented if none exists. |
---|
| 1439 | </Para> |
---|
| 1440 | |
---|
| 1441 | <Para> |
---|
| 1442 | If you use "*cs out" more than once, the second and subsequent commands are |
---|
| 1443 | silently ignored - this makes it possible to combine two datasets with |
---|
| 1444 | different "*cs out" settings without having to modify either of them. |
---|
| 1445 | </Para> |
---|
| 1446 | |
---|
| 1447 | <Para> |
---|
| 1448 | Something to be aware of with "*cs" is that altitudes are currently assumed to |
---|
| 1449 | be "height above the ellipsoid", whereas GPS units typically give you "height |
---|
| 1450 | above sea level", or more accurately "height above a particular geoid". This |
---|
| 1451 | is something we're looking at how best to address, but you shouldn't need to |
---|
| 1452 | worry about it if your fixed points are in the same coordinate system as your |
---|
| 1453 | output, or if they all use the same ellipsoid. For a more detailed discussion |
---|
| 1454 | of this, please see: http://expo.survex.com/handbook/survey/coord.htm |

[513935e] | 1823 | The *declination command is the modern way to specify magnetic declinations in |
---|
[f65e7e9] | 1824 | Survex. Prior to 1.2.22, *calibrate declination was used instead. If you |
---|
| 1825 | use a mixture of *calibrate declination and *declination, they interact in |
---|
| 1826 | the natural way - whichever was set most recently is used for each compass |
---|
| 1827 | reading (taking into account survey scope). We don't generally recommend |
---|
| 1828 | mixing the two, but it's useful to understand how they interact if you want to |
---|
| 1829 | combine datasets using the old and new commands, and perhaps if you have a |
---|
| 1830 | large existing dataset and want to migrate it without having to change |
---|
| 1831 | everything at once. |
---|
[513935e] | 1832 | </Para> |
---|
| 1833 | |
---|
| 1834 | <Para> |
---|
| 1835 | Magnetic declination is the difference between Magnetic North and True North. |
---|
| 1836 | It varies both with location and over time. Compass bearings are measured |
---|
| 1837 | relative to Magnetic North - adding the magnetic declination gives bearings |
---|
| 1838 | relative to True North. |
---|
| 1839 | </Para> |
---|
| 1840 | |
---|
| 1841 | <Para> |
---|
| 1842 | If you have specified the output coordinate system (using *cs out) then you can |
---|
| 1843 | use *declination auto (and we recommend that you do). This is supported since |
---|
| 1844 | Survex 1.2.21 and automatically calculates magnetic declinations based on the |
---|
| 1845 | IGRF (International Geomagnetic Reference Field) model for the specified date |
---|
| 1846 | of each survey and at the specified representative location (given in the |
---|
| 1847 | current input coordinate system, as set with *cs). Survex 1.2.27 and |
---|
| 1848 | later also automatically correct for grid convergence (the difference between |
---|
| 1849 | Grid North and True North) when *declination auto is in use, based on the same |
---|
| 1850 | specified representative location. |
---|
| 1851 | </Para> |
---|
| 1852 | |
---|
| 1853 | <Para> |
---|
| 1854 | You might wonder why Survex needs a representative location instead of |
---|
| 1855 | calculating the magnetic declination and grid convergence for the actual |
---|
| 1856 | position of each survey station. The reason is that we need to adjust the |
---|
| 1857 | compass bearings before we can solve the network to find survey station |
---|
| 1858 | locations. Both magnetic declination and grid convergence don't generally vary |
---|
| 1859 | significantly over the area of a typical cave system - if you are mapping a |
---|
| 1860 | very large cave system, or caves over a wide area, or are working close to a |
---|
| 1861 | magnetic pole or where the output coordinate system is rather distorted, then |
---|
| 1862 | you can specify *declination auto several times with different locations - the |
---|
| 1863 | one currently in effect is used for each survey leg. |
---|
| 1864 | </Para> |
---|
| 1865 | |
---|
| 1866 | <Para> |
---|
| 1867 | Generally it's best to specify a suitable output coordinate system, and use |
---|
| 1868 | *declination auto so Survex corrects for magnetic declination and grid |
---|
| 1869 | convergence for you. Then Aven knows how to translate coordinates to allow |
---|
| 1870 | export to formats such as GPX and KML, and to overlay terrain data. |
---|
[58c7b459] | 1871 | </Para> |
---|
| 1872 | |
---|
| 1873 | <Para> |
---|
[513935e] | 1874 | If you don't specify an output coordinate system, but fix one or more points |
---|
| 1875 | then Survex works implicitly in the coordinate system your fixed points were |
---|
| 1876 | specified in. This mode of operation is provided for compatibility with |
---|
| 1877 | datasets from before support for explicit coordinate systems was added to |
---|
| 1878 | Survex - it's much better to specify the output coordinate system as above. |
---|
| 1879 | But if you have a survey of a cave which isn't connected to any known fixed |
---|
| 1880 | points then you'll need to handle it this way, either fixing an entrance |
---|
| 1881 | to some arbitrary coordinates (probably (0,0,0)) or letting Survex pick a |
---|
| 1882 | station as the origin. If the survey was all done in a short enough period |
---|
| 1883 | of time that the magentic declination won't have changed significantly, you |
---|
| 1884 | can just ignore it and Grid North in the implicit coordinate system will be |
---|
| 1885 | Magnetic North at the time of the survey. If you want to correct for magnetic |
---|
| 1886 | declination, you can't use *declination auto because the IGRF model needs the |
---|
| 1887 | real world coordinates, but you can specify literal declination values for each |
---|
| 1888 | survey using *declination <declination> <units>. Then Grid North |
---|
| 1889 | in the implicit coordinate system is True North. |

---|
[513935e] | 1893 | Note that the value specified uses the conventional sign for magnetic |

| 1894 | declination, unlike the old *calibrate declination which needed a value with |
---|
| 1895 | the opposite sign (because *calibrate specifies a zero error), so take care |
---|
| 1896 | when updating old data, or if you're used to the semantics of *calibrate |

| 1897 | declination. |

[40647f5] | 2727 | <Para> |
---|
[6048971] | 2728 | To utilise this command fully you need to understand what a |
---|
| 2729 | <emphasis>standard deviation</emphasis> is. |
---|
| 2730 | It gives a value to the 'spread' of the errors |
---|
[c1573d8] | 2731 | in a measurement. Assuming that these are normally distributed |
---|
[770157e] | 2732 | we can say that 95.44% of the actual lengths will fall within two |
---|
[40647f5] | 2733 | standard deviations of the measured length. i.e. a tape SD of |
---|
[770157e] | 2734 | 0.25 metres means that the actual length of a tape measurement |
---|
| 2735 | is within + or - 0.5 metres of the recorded value 95.44% of the time. |
---|
[40647f5] | 2736 | So if the measurement is 7.34m then the actual length is very |
---|
[6048971] | 2737 | likely to be between 6.84m and 7.84m. This example corresponds |
---|
[40647f5] | 2738 | to BCRA grade 3. Note that this is just one interpretation of |
---|
[770157e] | 2739 | the BCRA standard, taking the permitted error values as 2SD 95.44% |
---|
[40647f5] | 2740 | confidence limits. If you want to take the readings as being some |
---|
[6048971] | 2741 | other limit (e.g. 1SD = 68.26%) then you will need to change the BCRA3 |
---|
[c1573d8] | 2742 | and BCRA5 files accordingly. This issue is explored in more |
---|
[40647f5] | 2743 | detail in various surveying articles. |

[5b5a89f] | 3453 | <Para>This is done by using the *SD command to specify the appropriate |

| 3454 | errors for the radiolocation `survey leg' so that the loop closure |

| 3457 | |

| 3458 | <Para>The best approach for a radiolocation where the underground station |
---|
| 3459 | is vertically below the surface station is to represent it as a |
---|
| 3460 | plumbed leg, giving suitable SDs for the length and plumb angle. The |
---|
| 3461 | horizontal positioning of this is generally quite accurate, but the |
---|
| 3462 | vertical positioning may be much less well known. E.g: we have a |
---|
| 3463 | radiolocation of about 50m depth +/- 20m and horizontal accuracy of |
---|
| 3464 | +/- 8m. Over 50m the +/-8m is equivalent to an angle of 9 degrees, so |
---|
| 3465 | that is the expected plumb error. 20m is the expected error in the |
---|
[e74904e] | 3466 | length. To get the equivalent SD we assume that 99.74% of readings will |
---|
[5b5a89f] | 3467 | be within 3 standard deviations of the error value. Thus we divide the |

| 3468 | expected errors by 3 to get the SD we should specify: |

---|
| 3864 | Survex can read Compass survey data - both raw data (.DAT and .MAK |

| 3865 | files) and processed survey data (.PLT and .PLF files). You can even |
---|
[6af6d51] | 3866 | use <command>*include compassfile.dat</command> in a <filename>.svx</filename> file and |

| 3870 | <Para> |
---|
| 3871 | One point to note (this tripped us up!): station names in DAT files are |
---|
| 3872 | case sensitive and so Survex reads DAT files with the equivalent of |
---|
| 3873 | <command>*case preserve</command>. The default in SVX files is |
---|
| 3874 | <command>*case lower</command>. So this won't work: |

| 3880 | Because the CE1 in the *fix is actually interpreted as ce1. This is |
