The application Volume Measurement allows you to measure the area and volume of stockpiles bounded by a maximum of 500 points connected by straight lines in real time. These points can be measured, taken from memory, or set via the keyboard. The measured volume is projected onto an inclined reference plane defined by its points (3D). Volumes of embankments are automatically measured by calculating the digital terrain model (DTM) in the local coordinate system, where the first base point is taken as the origin. Triangulations of irregularly distributed points, known as Triangulated Irregular Networks (TIN), allow incorporation of terrain break lines (ridges, valleys), and extreme locations (e.g., summits) to better represent the terrain.

Handy features:

- Editing coordinates (recalculating P, Lat, Lon, H ⇆ P, X, Y, H)
- Adding contour lines
- Adding direction arrow with slope labels (two-point)
- Removing duplicate points
- Clipping points that go beyond the base surface
- Calculating the area
- Exporting points to Excel (CSV)
- Exporting survey to SVG, KML (viewable in Google Earth)
- Cylindrical coordinates (azimuth (θ), distance (r) to the previous point)
- Exporting the surface to AutoCAD (drag the script generated by the application from the Explorer to the AutoCAD workspace to automatically draw the surface from 3D faces)
- Positioning the receiver (phone screen) by the Sun for easy orientation on the terrain
- Double tap shifts the center of the zoom

Location may use sources like Wi-Fi, mobile networks, and sensors, which reduces the accuracy of measurements. For this reason: settings > location > Google Location Accuracy > Off. While making a survey, hold the phone in a vertical position because the phase center of the antenna is located at the top of the device.

The latest stage of accuracy enhancement uses the L5 band and is now fully deployed. GPS receivers released in 2019 that use the L5 band can have much higher accuracy, pinpointing to within 30 centimeters or 11.8 inches.

Even when GPS is disabled, the approximate location (1°) and time (~15min) are sufficient to rotate the upper, middle point of the screen, which points to the north if the direction of the yellow asterisk coincides with the Sun.
