## What is Engineering Survey Calculator?

The field companion for surveyors and civil engineers — 42 calculators, reference tables, and field tools in USCS and SI units.

Engineering Survey Calculator covers the everyday math of land surveying, from tape corrections to vertical curves, with instant results, clearly stated formulas, and one-tap unit switching.

CALCULATORS — grouped the way you work
• Errors & Precision: standard deviation, probable errors, error of the mean, full observation sets
• Taping Corrections: temperature, tension, sag, slope — individually or chained into one corrected length
• Leveling: curvature & refraction, reciprocal leveling, relative accuracy orders
• Traverse: latitudes & departures, misclosure, precision ratio, Bowditch adjustment, area by coordinates
• Curves: horizontal circular curves (T, L, C, M, E, D) and parabolic vertical curves with high/low point
• Stadia & Tacheometry, Earthwork volumes, Photogrammetry scales, and angle converters (DMS ⇄ decimal, azimuth ⇄ bearing)

AUTO-FILL REFERENCE DATA
Tap the magic wand to fill tape constants, instrument constants, camera focal lengths, and accuracy coefficients from built-in reference tables — no more hunting through handbooks. A dedicated Reference tab keeps all tables one tap away, in your chosen unit system.

FIELD TOOLS
• GPS field points: capture coordinates and elevation, then get distance and elevation difference between points
• Clinometer: measure slope angles with your device's sensors
• DMS quick-entry keyboard for angle inputs

SAVE, ORGANIZE, SHARE
Save any calculation to a project, attach field notes and photos, share results, and export a whole project as a PDF report.

BUILT FOR THE FIELD
• USCS and SI units everywhere, one tap apart
• Formulas shown with every result
• Favorites and search
• Dark mode, iPhone and iPad (side-by-side split view)
• Works fully offline
• Available in English, German, Spanish, French, Italian, Dutch, Portuguese, and Chinese (Simplified)

### 3/5 — Functional but not slick

*2013-06-11*

The app is pretty basic, the calculations seem to work fine, but the UI could use some work.  Units default to imperial too often, can't be set and stay on Metric.  It would also be nice to see things like resulting values for things like a slope correction to horizontal distance, ie. if I say SD is 10, slope is 32%, I do want to know the correction is subtracting 1.52, but it would be nice to also get 8.48 as the corrected HD shown somewhere.  Unique icons for calculations would help in searching too.

All in all it works, just klunkily.
