## Description

Your field book, in your pocket. Run leveling calculations and adjustments right at the site.<br><br>Level and Staff replaces the paper field book and the evening spreadsheet session. Enter readings as you work — the app computes height differences, adjusts the run, and hands you a finished file.<br><br>━━━━━━━━━━━━━━━━━━━━<br><br>CALCULATION &amp; ADJUSTMENT<br><br>- Manual and automatic adjustment of measurements<br>- Line adjustment — misclosure distributed across individual staff stations<br>- Loop adjustment for runs that start and end at the same elevation<br>- Maximum permissible error calculation to verify run quality<br>- All values rounded to the nearest millimetre<br><br>IMPORT FROM DIGITAL LEVELS<br><br>- Leica — GSI<br>- Sokkia SDL — SDR<br>- Trimble DiNi — DAT<br>- Generic CSV<br><br>Pull data straight from the instrument instead of retyping it.<br><br>EXPORT<br><br>- Detailed report of raw and adjusted elevations<br>- Results saved to a .CSV file<br><br>YOUR DATA IS SAFE<br><br>- Automatic saving whenever the app closes, including by accident<br>- Data kept in the level_books folder<br>- Remove a bad row with a long press (1 second) on its height-difference cell<br><br>SITE CONTEXT<br><br>- Store GPS coordinates of the project site directly in your notes<br><br>━━━━━━━━━━━━━━━━━━━━<br><br>COLLIMATION CHECK<br><br>A built-in calculator for the line-of-sight (i) correction.<br><br>Fields unlock in sequence — I1, A1, I2, A2 — each one opening only after the previous is filled. No skipped readings, no mixed-up values.<br><br>The result appears at the bottom of the screen as soon as the last value is entered:<br><br>x = ((I1 − I2) − (A1 − A2)) / 2<br>x = ((1270 + 1910) − (1674 + 1520)) / 2 = −7<br><br>Corrected reading: A2 + x = 1520 + (−7) = 1513<br><br>━━━━━━━━━━━━━━━━━━━━<br><br>TIPS FOR ACCURACY<br><br>- Rock the staff back and forth and record the lowest reading<br>- Keep backsights and foresights roughly equal in length to cancel out collimation error<br><br>━━━━━━━━━━━━━━━━━━━━<br><br>VIDEO<br><br>Walkthrough of entering survey data and adjusting equalization manually:<br>https://youtu.be/4szdeGg3iNM
