---|
[ff003b3] | 128 | <Para>&survexsuite; is a multi-platform open-source cave surveying |
---|
[6e420ba] | 129 | package. |
---|
[d959ab2] | 130 | Version 1.2 |
---|
[64d37a3] | 131 | currently runs on &unix;, Microsoft Windows 95/NT and |
---|
[56ad6ad] | 132 | successors, and Mac OS X. |
---|
[64d37a3] | 133 | We're investigating support for various |
---|
[6e420ba] | 134 | palmtop devices. |
---|
[f9535d4] | 135 | Version 1.0 has fewer features, but also runs on &msdos; and &riscos; machines. |
---|

---|
[40647f5] | 137 | |
---|
[c1573d8] | 138 | <Para>We are well aware that not everyone has access to super hardware |
---|
| 139 | - often surveying projects are run on little or no budget and any |
---|
| 140 | computers used are donated. We aim to ensure that &survexsuite; is |
---|
[57a5ebb] | 141 | feasible to use on low-spec machines. Obviously it won't be as |
---|
| 142 | responsive, but we intend it to be usable. |
---|
| 143 | Please help us to achieve this by giving us some feedback |
---|
[c1573d8] | 144 | if you use &survexsuite; on a slow machine.</Para> |

---|
[c1eff09] | 147 | quickly and has a very effective, real-time cave viewer which allows |
---|
[0706076] | 148 | you to rotate, zoom, and pan the cave using mouse or keyboard. We have |
---|
| 149 | tested it extensively using &cucc; and &arge;'s surveys of the caves |
---|
[a3f8737] | 150 | under the Loser Plateau in Austria (over 22,000 survey legs, and over |
---|
| 151 | 120km of underground survey data). This can all be processed in around |
---|
| 152 | 10 seconds on a low-end netbook. |
---|
[0706076] | 153 | Survex is also used by many other survey projects around the world, |

[ff003b3] | 713 | <Para>Survey data is entered in the form of text files. You can use any |
---|
| 714 | text editor you like for this, so long as it has the capability of |
---|
[1a50c3c] | 715 | writing a plain ASCII text file. The data format is very flexible; |
---|
[eb48e2b] | 716 | unlike some other cave surveying software, Survex does not require |
---|
| 717 | survey legs to be rearranged to suit the computer, and the ordering |
---|
| 718 | of instrument readings on each line is fully specifiable. So you can enter |
---|
[1a50c3c] | 719 | your data much as it appears on the survey notes, which is important |
---|
[eb48e2b] | 720 | in reducing the opportunities for transcription errors. |
---|
[1a50c3c] | 721 | </Para> |
---|
| 722 | |
---|
[191536f] | 723 | <Para> |
---|
[a7e3295] | 724 | Also all the special characters are user-definable - for example, |
---|
[191536f] | 725 | the separators can be spaces and tabs, or commas (e.g. when exporting from a |
---|
| 726 | spreadsheet), etc; the decimal point can be a slash (for clarity), a comma |
---|
[1a50c3c] | 727 | (as used in continental Europe), or anything else you care to choose. |
---|
| 728 | This flexibility |
---|
[ff003b3] | 729 | means that it should be possible to read in data from almost any sort of |
---|
[191536f] | 730 | survey data file without much work. |

[1a50c3c] | 734 | of survey legs. You can enter or process data in any order and &survexsuite; will |
---|
[c1573d8] | 735 | read it all in before determining how it is connected. You can also use the |
---|
| 736 | hierarchical naming so that you do not need to worry about using the same |
---|
| 737 | station name twice. |
---|

---|
[1a50c3c] | 740 | <!-- FIXME don't encourage separate processing --> |
---|
[3d5fb53] | 741 | <Para>The usual arrangement is to have one file which lists all the others |
---|
[1a50c3c] | 742 | that are included (e.g., <filename/161.svx/). Then |
---|
[375f7f6] | 743 | <command/cavern 161/ will process all your data. To just process a |
---|
| 744 | section use the filename for that section, e.g. <command/cavern dtime/ |
---|
[c1573d8] | 745 | will process the dreamtime file/section of Kaninchenhöhle. To |
---|
[1a50c3c] | 746 | help you out, if all legs in a survey are connected to one another |
---|
| 747 | but the survey has no fixed points, cavern |
---|
[c1573d8] | 748 | will 'invent' a fixed point and print a warning message to this |

| 749 | effect. |

[40647f5] | 754 | can have one file per trip, or per area of the cave, or just one |
---|
| 755 | file for the whole cave if you like. |
---|
[a7e3295] | 756 | On a large survey project it makes sense to group related surveys in the |

[a4458fd5] | 783 | <Para>&survexsuite; has a powerful system for naming stations. It |
---|
[eb48e2b] | 784 | uses a hierarchy of survey names, similar to the nested folders |

| 785 | your computer stores files in. |
---|
| 786 | So point 6 in the entrance survey of Kaninchenhöhle |
---|
[a4458fd5] | 787 | (cave number 161) is referred to as: 161.entrance.6 |
---|
| 788 | </Para> |
---|
| 789 | |
---|
| 790 | <Para>This seems a natural way to refer to station names. It also |

---|
[eb48e2b] | 793 | another file, specifying a new prefix. So to group 3 nearby caves |

---|
| 1199 | What I mean (though failed to express very well) is that a dataset without |
---|
| 1200 | this information isn't the same dataset (in general anyway). For example: |
---|
| 1201 | |
---|
| 1202 | A1 a2 10.32 140 -05 |
---|
| 1203 | a2 a3 4.91 041 -01 |
---|
| 1204 | a1 a3 7.01 206 02 |
---|
| 1205 | |
---|
| 1206 | is either a traverse of 3 legs or a (probably badly misclosed) loop. If |
---|
| 1207 | these names are on the original survey notes, the surveyors ought to say |
---|
| 1208 | whether "A1" is the same as "a1" (although the usual case for using this |
---|
| 1209 | feature is probably for importing data from elsewhere). Similarly for |
---|
| 1210 | truncation. Whether a clino of +/-90 degrees (or +/-100 grad, etc) is |
---|
| 1211 | interpreted as a plumb is something that should have been noted in the cave |
---|
| 1212 | (unless it's implicit because it's standard practice for a survey project). |
---|
| 1213 | |
---|
| 1214 | It's a similar issue to calibration data in many ways. You can argue it's |
---|
| 1215 | not part of "the survey", but without it the survey won't be the same shape, |
---|
| 1216 | and it's not useful to process the same survey with different settings for |
---|
| 1217 | compass calibration or name case sensitivity. |
---|
| 1218 | |
---|
| 1219 | >Clearly that is unhelpfully strict, but it is |
---|
| 1220 | >important to be semantically clear about what is 'data' and what is 'commands |
---|
| 1221 | >or meta-data' which describe what to do with/how to interpret that data. |
---|
| 1222 | |
---|
| 1223 | Think of the lines starting with a "*" as "command or meta-data". |
---|
| 1224 | |
---|
[3d5fb53] | 1225 | >The most-correct solution to this is (I believe) Martin Heller's idea about |
---|
[c1573d8] | 1226 | >including 'rules' in the datastream, but that's too big a subject for right |
---|
| 1227 | >now. |
---|
| 1228 | > |
---|
| 1229 | >The reason '-C' was made into a command-line option, was that it made very |
---|

---|
[375f7f6] | 1231 | >you suddenly tell cavern to become case-sensitive halfway through a run? |
---|
[c1573d8] | 1232 | |
---|
| 1233 | -C has always had 3 settings - "leave case alone", "force to lower", and |
---|
| 1234 | "force to upper". It doesn't really mean "case sensitivity" but rather |
---|
| 1235 | something like "case processing". So you can usefully change it during a |
---|
| 1236 | run. So if my dataset treats "NoTableChamber" (so named because it was |
---|
| 1237 | lacking in furniture) as different from "NotableChamber" (which was notable |
---|
| 1238 | for other reasons) I can process it with a dataset from someone else which |
---|
| 1239 | needs to be treated as case insensitive like so: |
---|
| 1240 | |
---|
| 1241 | *begin my_cave |
---|
| 1242 | *include my_dataset |
---|
| 1243 | *end my_cave |
---|
| 1244 | |
---|
| 1245 | *equate my_cave.NoTableChamber.14 your_cave.linkpassage.13 |
---|
| 1246 | |
---|
| 1247 | *begin your_cave |
---|
| 1248 | *case tolower |
---|
| 1249 | *include your_dataset |
---|
| 1250 | *end your_cave |
---|
| 1251 | |
---|
| 1252 | You may be thinking of -U<n>, which used to mean "only compare the first n |
---|
| 1253 | characters of station names", but that doesn't allow arbitrary datasets to |
---|
| 1254 | be processed together. |
---|
| 1255 | |
---|
| 1256 | So we changed it to mean "truncate station names to n characters", and |
---|
| 1257 | allowed it to be changed at any point, rather than being set once for the |
---|
| 1258 | whole run. |

---|
| 1394 | |
---|
[ad5bd05] | 1395 | <Para> |
---|
| 1396 | By default, Survex works in an unspecified coordinate system (and this was the |
---|
| 1397 | only option before *cs was added). However, it's useful for coordinate system |
---|
| 1398 | which the processed survey data is in to be specified if you want to use the |
---|
| 1399 | processed data in ways which required knowing the coordinate system (such as |
---|
| 1400 | exporting a list of entrances for use in a GPS). You can now do this by using |
---|
| 1401 | "*cs out". |
---|
| 1402 | </Para> |
---|
| 1403 | |
---|
| 1404 | <Para> |
---|
| 1405 | It is also useful to be able to take coordinates for fixed points in whatever |
---|
| 1406 | coordinate system you receive them in and put them directly into Survex, rather |
---|
| 1407 | than having to convert with an external tool. For example, you may have your |
---|
| 1408 | GPS set to show coordinates in UTM with the WGS84 datum, even though you want |
---|
| 1409 | the processed data to be in some local coordinate system. And someone else |
---|
| 1410 | may provide GPS coordinates in yet another coordinate system. You just need |
---|
| 1411 | to set the appropriate coordinate system with "*cs" before each group of "*fix" |
---|
| 1412 | commands in a particular coordinate system. |
---|
| 1413 | </Para> |
---|
| 1414 | |
---|
| 1415 | <Para> |
---|
| 1416 | If you're going to make use of "*cs", then the coordinate system must be |
---|
| 1417 | specified for everything, so a coordinate system must be in effect for all |
---|
| 1418 | "*fix" commands, and you must set the output coordinate system before any |
---|
| 1419 | points are fixed. |
---|
| 1420 | </Para> |
---|
| 1421 | |
---|
| 1422 | <Para> |
---|
| 1423 | Also, if "*cs" is in use, then you can't omit the coordinates in a "*fix" |
---|
| 1424 | command, and a fixed point won't be invented if none exists. |
---|
| 1425 | </Para> |
---|
| 1426 | |
---|
| 1427 | <Para> |
---|
| 1428 | If you use "*cs out" more than once, the second and subsequent commands are |
---|
| 1429 | silently ignored - this makes it possible to combine two datasets with |
---|
| 1430 | different "*cs out" settings without having to modify either of them. |
---|
| 1431 | </Para> |
---|
| 1432 | |
---|
| 1433 | <Para> |
---|
| 1434 | Something to be aware of with "*cs" is that altitudes are currently assumed to |
---|
| 1435 | be "height above the ellipsoid", whereas GPS units typically give you "height |
---|
| 1436 | above sea level", or more accurately "height above a particular geoid". This |
---|
| 1437 | is something we're looking at how best to address, but you shouldn't need to |
---|
| 1438 | worry about it if your fixed points are in the same coordinate system as your |
---|
| 1439 | output, or if they all use the same ellipsoid. For a more detailed discussion |
---|
| 1440 | of this, please see: http://expo.survex.com/handbook/survey/coord.htm |

[fe16ba3] | 2094 | X is Easting, Y is Northing, and Z is altitude. This convention was chosen |
---|
| 2095 | since on a map, the horizontal (X) axis is usually East, and the vertical |
---|
| 2096 | axis (Y) North. The choice of altitude (rather than depth) for Z is taken |
---|
| 2097 | from surface maps, and makes for less confusion when dealing with cave |
---|
| 2098 | systems with more than one entrance. It also gives a right-handed |

[40647f5] | 2518 | <Para> |
---|
[6048971] | 2519 | To utilise this command fully you need to understand what a |
---|
| 2520 | <emphasis>standard deviation</emphasis> is. |
---|
| 2521 | It gives a value to the 'spread' of the errors |
---|
[c1573d8] | 2522 | in a measurement. Assuming that these are normally distributed |
---|
[770157e] | 2523 | we can say that 95.44% of the actual lengths will fall within two |
---|
[40647f5] | 2524 | standard deviations of the measured length. i.e. a tape SD of |
---|
[770157e] | 2525 | 0.25 metres means that the actual length of a tape measurement |
---|
| 2526 | is within + or - 0.5 metres of the recorded value 95.44% of the time. |
---|
[40647f5] | 2527 | So if the measurement is 7.34m then the actual length is very |
---|
[6048971] | 2528 | likely to be between 6.84m and 7.84m. This example corresponds |
---|
[40647f5] | 2529 | to BCRA grade 3. Note that this is just one interpretation of |
---|
[770157e] | 2530 | the BCRA standard, taking the permitted error values as 2SD 95.44% |
---|
[40647f5] | 2531 | confidence limits. If you want to take the readings as being some |
---|
[6048971] | 2532 | other limit (e.g. 1SD = 68.26%) then you will need to change the BCRA3 |
---|
[c1573d8] | 2533 | and BCRA5 files accordingly. This issue is explored in more |
---|
[40647f5] | 2534 | detail in various surveying articles. |

[40647f5] | 2992 | <Para> |
---|
[ff003b3] | 2993 | &survexsuite; places few restrictions on station naming (see "Survey |

| 2994 | Station Names" in the previous section), so you can number the stations |
---|
| 2995 | as they were in the original survey notes. Although not apparent from |
---|
| 2996 | this example, there is no requirement for each leg to connect to an |
---|
| 2997 | existing station. &survexsuite; can accept data in any order, and will |

[40647f5] | 3007 | <Para> |

| 3008 | Most caves will take more than just one survey trip to map. Commonly |

| 3009 | the numbering in each survey will begin at 1, so we need to be |

[fbc41c2] | 3015 | To accomplish this, &survexsuite; has a very flexible system of hierarchical |

[40647f5] | 3016 | prefixes. All you need do is give each survey a unique name or |

[a4458fd5] | 3235 | <!-- FIXME comments from David Gibson here --> |
---|
[5b5a89f] | 3236 | <Para>This is done by using the *SD command to specify the appropriate |
---|
| 3237 | errors for the radiolocation `survey leg' so that the loop closure |

---|
| 3240 | |
---|
| 3241 | <Para>The best approach for a radiolocation where the underground station |
---|
| 3242 | is vertically below the surface station is to represent it as a |
---|
| 3243 | plumbed leg, giving suitable SDs for the length and plumb angle. The |
---|
| 3244 | horizontal positioning of this is generally quite accurate, but the |
---|
| 3245 | vertical positioning may be much less well known. E.g: we have a |
---|
| 3246 | radiolocation of about 50m depth +/- 20m and horizontal accuracy of |
---|
| 3247 | +/- 8m. Over 50m the +/-8m is equivalent to an angle of 9 degrees, so |
---|
| 3248 | that is the expected plumb error. 20m is the expected error in the |
---|
[e74904e] | 3249 | length. To get the equivalent SD we assume that 99.74% of readings will |
---|
[5b5a89f] | 3250 | be within 3 standard deviations of the error value. Thus we divide the |

---|
| 3641 | Survex can read Compass survey data - both raw data (.DAT and .MAK |

---|
| 3648 | One point to note (this tripped us up!): station names in DAT files are |
---|
| 3649 | case sensitive and so Survex reads DAT files with the equivalent of |
---|
| 3650 | <command>*case preserve</command>. The default in SVX files is |

| 3651 | <command>*case lower</command>. So this won't work: |
