SurvEngTrav

This app supports Android 4.4 and above

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.

For a Closed Traverse the application initially computes and outputs the following Data:
1) Whole Circle Bearing and Coordinates for each Observed Station
2) Output of Miss-Closure for Eastings and Northings
3) Output of Calculated Theoretical Angle total for Traverse loop
4) Output of Observed Angle total for Traverse loop
5) Output of Angular Miss-closure for Traverse loop
6) Output of Angular correction for Traverse loop
7) The total Distance of completed Traverse
8) Balances observed Angles
9) Re-Calculates Coordinates relative to balanced Angles
10) Shows Traverse precision
11) Apply's the Bowditch Correction Rule to finalise Coordinate precision.
