Cave Depth Total from Station Chain Calculator
Actual independently surveyed station vertical range, not total absolute ascent/descent or entrance-relative maximum depth. Common datum and coverage external.
Description
Cave vertical relief is the difference between the highest and lowest surveyed station elevations.
Cave vertical relief is the difference between the highest and lowest surveyed station elevations.1
It uses a common datum rather than summing every vertical shot.
When to use Cave Depth Total from Station Chain Calculator
Use this tool to obtain observedVerticalReliefMeters, observedMinimumStationElevationMeters, observedMaximumStationElevationMeters from the supplied records using the stated calculation. Establish the survey or observation scope, reference frame, units and independently applicable calibration or qualified plan.
How to use Cave Depth Total from Station Chain Calculator and understand its results
- Establish the survey or observation scope, reference frame, units and independently applicable calibration or qualified plan.
- Enter actualStationElevationsRelativeToDatumMeters, using the field meanings and rules below, then run the tool.
- Read result.observedVerticalReliefMeters, result.observedMinimumStationElevationMeters, result.observedMaximumStationElevationMeters. Use the units and sign conventions below, and review any unknown records separately.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualStationElevationsRelativeToDatumMeters | Actual station elevations relative to datum meters | list of number | Required |
Require a nonempty finite common-datum station-elevation list. Return maximum minus minimum as vertical relief and both extreme elevations. Signed elevations and one-station zero relief are accepted.
reliefMeters=max(elevations)−min(elevations) Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Qualified observed calculation or explicit reference | object |
| result.observedVerticalReliefMeters | Highest minus lowest station elevation on the common datum. | number |
| result.observedMinimumStationElevationMeters | Lowest supplied station elevation on the declared datum. | number |
| result.observedMaximumStationElevationMeters | Highest supplied station elevation on the declared datum. | number |

}Limitations and assumptions
The actual observation coverage, calibration and qualified plan determine applicability. A numerical result does not establish survey accuracy, route suitability, atmosphere conditions or equipment adequacy beyond the declared comparison.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries, subject to the narrower lengths and code rules above. Extremely large composite outputs are rejected.
Alternative or Complementary methods
For a related step, use Length Record Ranking Comparator: Cave-length rankings require compatible, independently established record conventions. For a complementary comparison, use Depth Record Ranking Comparator: Cave-depth rankings depend on compatible datum and vertical-relief conventions.
