The primary design for this application is for onsite Engineering Surveyors to calculate Traverse data from hand booked angles and distances which can be calculated into final Station Coordinates quickly and precisely. The units of input for angles are: Degrees, Minutes and Seconds as is the output of the calculated data. Coordinate data is Input as (UK) Eastings and Northings as is the output of Coordinate data. The application calculates data for both a simple Open Traverse or, more complicated Closed Traverses.

For Closed Traverses there are 3 stages of calculation that this application will carry out and these being:
1) Calculation of unadjusted Coordinates
2) Calculation of Coordinates after automatic Angular adjustment is applied to Observed Angles.
3) Calculation of Coordinates after a Bowditch Correction has automatically been applied to the observed Distances.

Within all 3 stages there is a print function to display the calculated Coordinates which can be highlighted, to be selected for copying and pasting into Email, Text Messaging or can be Bluetooth'ed to a computer or other device.

For an Open Traverse the application Initially calculates and outputs the following Data:
1) Whole Circle Bearing and Coordinates for each Observed Station
2) The total distance of completed Traverse.

The Link Traverse Procedure has been designed to carry out a full Link Traverse adjustment which includes:
1) Calculation of unadjusted WCB and raw coordinates (Including Raw Misclosure)
2) Calculation of adjusted Angles and WCB after Link Traverse Angle Balancing procedure
has been applied.
3) Calculation of actual Misclosure
4) Calculation of Partial Coordinates
5) Calculation of Total Coordinates
6) Calculation of Bowditch corrected coordinates.

The Whole Circle Bearing Direction Procedure can be used by Surveyors and Engineers for tunnelling construction to check and make sure that the tunnel is heading in the correct direction. (This method is basically an open Traverse without the use of coordinates) This method of Surveying requires observed angles only, used to calculate the whole circle bearings throughout the length of a tunnel during construction. ## Similar extensions and apps - [SurvEngCalc](https://chrome-stats.com/d/com.nsbasic.Project1) — 206 users - [Harcourt Traverse & Surveying](https://chrome-stats.com/d/com.harcourttraverse) — 2,452 users, 4.20 / 5 - [Coordinate Calc (Traverse)](https://chrome-stats.com/d/jp.ito.StCalc) — 1,734 users - [AngleDistCalc - Traverse Calc](https://chrome-stats.com/d/com.jps.angledistcalc) — 1 users - [Traverse & Survey Error Calc](https://chrome-stats.com/d/com.traverseerrorcalculation) — 2,121 users - [SurveyCalc Field](https://chrome-stats.com/d/com.juncortech.administrator.surveycalcfield) — 439 users - [Surveying Calc: COGO & Maps](https://chrome-stats.com/d/com.surveyingnext.surveyingcalc) — 862 users - [Land Surveyor](https://chrome-stats.com/d/com.landsurveyor) — 12,883 users, 3.40 / 5 - [Handy Surveying](https://chrome-stats.com/d/net.binaryearth.handysurveying) — 2,892 users, 5.00 / 5 - [Survey Soft](https://chrome-stats.com/d/vlonn.survey.survey_soft) — 31,843 users - [Geodetic NET](https://chrome-stats.com/d/com.GeodeticNET) — 2,812 users - [SurvEngLev](https://chrome-stats.com/d/com.nsbasic.SurvEngLev) — 40 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.nsbasic.SurvEngCalc?hl=ja)
