Geoclass is a professional surveying calculator built for engineers (mining, civil, and environmental), surveyors, and GIS technicians. It combines coordinate geometry (COGO), UTM map, coordinate conversion for 592 systems across 55 countries, slope calculations, and area calculation, all in a single app.

15 COGO CALCULATION TOOLS
• Calculate Coordinate — new point from bearing + distance
• Distance and Bearing — inverse calculation between two points
• Forward Intersection — from two known points + angles
• Backward Intersection (Resection) — Tienstra's method from 3 known points
• Line-Line Intersection — intersection of two straight lines
• Middle Point — midpoint between two points
• Perpendicular Foot — drop a perpendicular from a point to a line
• Circle by 3 Points — circumscribed circle through three points
• Generate Coordinates — interpolate points along a line
• Interior Angle — angle from three coordinate points
• Bearing from Angles — compute bearings from measured angles
• Angle Converter — Degree ↔ Radian ↔ Grad ↔ Mil
• Helmert Transformation — 2D similarity (4-parameter) transformation
• Horizontal Curve — road/highway curve calculations
• Map Scale — ground distance ↔ map distance

INTERACTIVE UTM MAP
• Real-time GPS with Lat/Long, UTM, and MGRS coordinates
• Compass with azimuth angle display
• Add, edit, and manage points, lines, and areas on the map
• Measure distances and navigate to coordinates
• UTM zone grid overlay
• Persistent GeoPackage storage for all map data

COORDINATE CONVERTER — 592 SYSTEMS, 55 COUNTRIES
Convert between local Cartesian and geographic coordinate systems for:
Algeria, Australia, Belgium, Brazil, Canada, Chile, Egypt, Ethiopia, Finland, France, Germany, Greece, India, Indonesia, Iran, Iraq, Ireland, Italy, Kenya, Malaysia, Mexico, Morocco, Myanmar, Netherlands, Nigeria, Norway, Pakistan, Peru, Philippines, Poland, Portugal, Russia, Saudi Arabia, Spain, Sweden, Tanzania, Thailand, Turkey, UAE, United Kingdom, USA (state-level), and more.
Powered by the PROJ library — the same engine used by QGIS and ArcGIS.

IMPORT & EXPORT in UTM MAP MODULE
• Import: CSV/TXT, GeoJSON, KML, KMZ
• Export: Text, DXF, GeoJSON, GeoPackage
• GDAL-accelerated import for large spatial datasets

ADDITIONAL TOOLS
• Slope Calculator — from levels, coordinates, or horizontal/vertical distances
• Area from Coordinates — Shoelace formula with graphical shape display
• LatLong ↔ UTM Converter — WGS84 bidirectional conversion with GPS
• DMS ↔ Decimal degree converter

KEY FEATURES
• Configurable units: meters, km, miles, nautical miles, yards, feet, inches
• Angle units: degrees, DMS, DM, grads (gon)
• Adjustable decimal precision for distances and angles
• North-East / East-North coordinate ordering
• Works offline — all calculations run locally on your device
