Surveying Calculator has commonly used land surveying tools. This includes coordinate geometry calculations offline point data collection displaying CAD GIS raster data and online maps in QGIS 3 project format. Surveying Calculator supports QGIS 3 projects. (qgs qgz)
Features:
- Jobs:
→ Create unlimited jobs for collecting points in SHP or GeoPackage formats with coordinate system code (EPSG code).
→ You can also prepare a job in QGIS on desktop with geospatial data. Import CAD GIS raster data or add online map services in QGIS. And transfer the data folder to Surveying_Calculator/projects folder on your device. Select the project in Jobs and Start Survey.
- Start Survey:
→ Collect unlimited points with "name" and "description". You can record your location or any place you want.
→ Add point with coordinates ( x y or latitude longitude).
→ Make surveying easy using QGIS projects.
- Map Viewer: Displays QGIS 3 projects.
→ It is possible to include geospatial data to display maps on this app;
→ Raster (GeoTIFF DEM JPEG PNG GRD XYZ ..)
→ CAD (DXF DGN v7)
→ GIS (ArcGIS shp Google Earth (kml kmz) GeoJSON GPX..)
→ Online map services (Open Street Maps Hybrid Maps Satellite Maps Terrain Maps..) Online maps can be prepared using QuickMapServices plugin in QGIS. You can add Open Street Maps hybrid or satellite maps in QGIS project for Surveying Calculator.
→ Geodatabase (GeoPackage Spatialite) formats in QGIS projects.
- Coordinate System support:
→ Supports 5000 different EPSG coordinate systems.
→ User can search a coordinate system with country name or coordinate system name on epsg.io site. And user can create jobs with a proper EPSG code.
→ The coordinate system can be projected ( in feet or meters units) or geographic (in degree)
- Generate Coordinates: Generate coordinates in latitude/ longitude or in X Y.
- Basic Surveying Tools: X(N) Y(E) Calculation Distance Azimuth Calculation Interior Angle Latitude Longitude from point distance and bearing
- Intersection Methods: Forward Intersection Line - Line Intersection Circle by 3 Points
- Distance between Coordinates: 2D 3D distance from X Y and distance from Latitude Longitude
- Area calculation from coordinates
- Degree - Decimal Conversion
- Coordinate Converter: WGS84 Latitude/Longitude to UTM XY or UTM XY to Latitude/Longitude Conventer 2D Helmert transformation
- Settings: Coordinate order of northing easting or latitude longitude. DMS or decimal options for geographic coordinate systems. Scale bar unit settings in metric or imperial.
- and more.
Surveying Calculator supports Android 6.0 and up. Minimum 2GB RAM with 300MB free space are recommended.

Some of the new modules have bugs with the new update:
- Start Survey: The app sometimes closes unexpectedly when GPS button is active. To prevent this problem turn off GPS mode before exiting Start Survey.
- Scale bar sometimes gives wrong results after adding layers and storing points.
- Projects sometimes display rotated map on Start Survey and Map View.
- Points are sometimes not recorded in Geopackage format.
It is planned to fix the weird bugs for next updates.
