Surveying Calculator

Surveying Calculator is the professional-grade coordinate geometry tool built specifically for civil engineers, mining professionals, surveyors, and GIS technicians who need precision calculations in the field or office.

Powered by 15 specialized COGO (coordinate geometry) calculation tools, you gain instant access to essential surveying operations without switching between multiple apps. Calculate new points from bearing and distance, perform inverse distance and bearing computations, execute forward and backward intersections, find line-line intersections, compute perpendicular distances, and generate interpolated coordinates along survey lines. Advanced features include Helmert transformation for datum shifts, horizontal curve calculations for road design, and circumscribed circle computations—all with professional accuracy.

Navigate and visualize your survey work with the interactive UTM map interface. Real-time GPS integration displays your position in latitude/longitude, UTM, and MGRS coordinates simultaneously. Add, edit, and manage survey points, lines, and areas directly on the map, measure distances between features, and overlay UTM zone grids for spatial reference. All map data persists in GeoPackage format, enabling seamless workflow between field reconnaissance and office analysis.

Coordinate conversion across 592 coordinate systems covering 55 countries eliminates the friction of working with local Cartesian projections. Whether you're surveying in Algeria, Australia, Brazil, Canada, India, the United States, Turkey, or anywhere globally, the built-in PROJ library—the same engine powering QGIS and ArcGIS—handles accurate transformations instantly. Support includes state-level coordinate systems for the USA and comprehensive coverage across Africa, Europe, Asia, and the Americas.

Import survey data in CSV, TXT, GeoJSON, KML, or KMZ formats, then export results as text, DXF, GeoJSON, or GeoPackage files. Full interoperability with QGIS, ArcGIS, Google Earth, and AutoCAD ensures your workflow integrates with industry-standard software. GDAL-accelerated import handles large spatial datasets without lag.

Additional calculation tools compute slope from levels, coordinates, or horizontal and vertical distances; calculate polygon areas using the Shoelace formula with graphical visualization; and convert between DMS and decimal degree formats. Customize units across meters, kilometers, miles, nautical miles, yards, feet, and inches; angle formats in degrees, DMS, DM, or grads; and decimal precision to match your project requirements. Choose North-East or East-North coordinate ordering, enable RTL language support, and work completely offline—all calculations run locally on your device with no internet required.

Surveying Calculator delivers professional surveying capability in your pocket.
