Engineering Survey Calculator vs Radius on Map +

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) Questions or suggestions? contact.pugal.apps@gmail.com

Easily make a radius on a map and share a url showing the radius via email or text message that can be viewed with any browser. The full version is a one-time purchase at a reasonable price. There is no recurring 'subscription' . Extra functionality of the full version includes: - Support for landscape and iPad split screen. - Share multiple radii in one url. - Lock a radius center to your current location. - Import radii stored as polygons in a .kml or .kmz file. You can import a file from a cloud service such as iCloud or Dropbox. - Export your radii as polygons saved to a kml file to view in Google Earth™ or other mapping applications. You can attach the .kml file to an email or save to iCloud, Dropbox, etc. - Ability to specify which radii show on the map by selecting them in the list view. - Search for keywords in name and/or notes field to find a specific saved radius. - Custom message header and footer. - No adverts Properties for each radius: - Center coordinate - Radius - Fill color and opacity - Perimeter color and opacity - Name - Notes (optional) Coordinate formats include: - Degrees - Degrees, Minutes - Degrees, Minutes, Seconds - UTM (Universal Transverse Mercator) - MGRS (Military Grid Reference System) Distance units include: - Kilometers - Miles - Nautical miles - Meters - Yards - Feet Loading satellite maps requires an internet connection. Datum used is WGS-84. Please visit the support page for more details.
