GPS Converter (SVY21/MM2000)

SVY21 & MM2000 Pro Converter: The Ultimate Mobile Toolkit for Land Surveyors & Civil Engineers SVY21 & MM2000 Pro Converter is a high-precision coordinate transformation and advanced fieldwork utility application designed specifically for professional Land Surveyors, Civil Engineers, Construction Managers, and GIS Specialists. Whether you are conducting site verification, topographic data collection, setting-out, or complex coordinate geometry (COGO) calculations, this application transforms your smartphone into a powerful, mobile-first surveying instrument. It provides seamless, mathematically rigorous conversions between Global WGS84 coordinates and the local survey datums used in Singapore (SVY21) and Myanmar (MM2000), alongside full Global UTM support. 🌟 MAJOR FEATURES & CAPABILITIES: 1. Precision Coordinate Conversions • Supports WGS84 (Lat/Lon) to SVY21 / MM2000 (Northing/Easting) and vice versa. • Global UTM Converter: Automatically identifies the correct UTM Zone and Hemisphere for any location globally. • High mathematical accuracy ensuring millimeter-level precision for professional use. 2. Advanced RT-GPS & Elevation Tracking • Real-Time GPS (RT-GPS): Monitor your live coordinates, Horizontal/Vertical Accuracy, PDOP, VDOP. • Geoid Models: Integrated with EGM96 (Global) and high-resolution EGM2008 for precise Mean Sea Level (MSL) elevation calculation. • Benchmark (BM) Mode: Set a local Benchmark height and apply Pole Height offsets for pinpoint Z-value MSL elevation tracking. 3. Comprehensive COGO Tools (Coordinate Geometry) • Bearing & Distance (Inverse/Traverse): Calculate distance and bearing between two points, or compute target coordinates using HP DMS (Degree, Minute, Second) or Decimal input formats. • Gradient & Elevation Calculator: Calculate slope percentages (%), 1:N ratios (Fall/Rise), and compute target elevations (Z2) accurately for drainage and road works. • Area Calculator: Calculate land area in Sq. Meters, Sq. Feet, Acres, and Hectares by selecting points directly from the map or imported CSV lists. 4. Visual Stakeout / Set Out Navigation • Navigate to specific design coordinates with real-time visual guidance. • Features an interactive navigation arrow driven by the device's compass, distance-to-target countdown, and audio beep alerts when approaching the target point (within 2 meters). 5. Site Plan (AutoCAD DXF) Viewer & Offline Maps • DXF Overlay: Load and view AutoCAD DXF site plans directly over the map. Features intelligent node-snapping for precise distance measurements on the fly. • Offline Mapping Engine: Download and cache high-resolution satellite and street maps (Tiles) for use in remote construction sites without internet access. 6. Professional Survey Camera • Capture site photos embedded with a highly detailed, non-removable GPS watermark. • Watermark Data Includes: Point Name, Accurate Address (Reverse Geocoding), Lat/Lon, Local N/E (SVY21/MM2000/UTM), MSL Elevation, Compass Bearing, Date & Time (with GMT timezone). • Mini-Map Integration: Automatically generates a mini street map with a location pin directly on the photo for indisputable site evidence. 7. Advanced Data Management (Import & Export) • Bulk CSV Converter: Import thousands of PNEZD points to convert between local grids and WGS84 instantly. • KML Export: Export your collected Topo points and DXF alignments directly to KML format for viewing on Google Earth. • Store, manage, and delete recorded points seamlessly within the app's local database. 🛠️ User-Friendly Interface: Optimized for outdoor field use with instant toggles, intuitive sub-menus, and support for both Light and Dark modes to reduce eye strain under direct sunlight.
