Earthwork. Volume Measurement play online

The application Volume Measurement allows you to measure the area, volume of stockpile bounded by a maximum of 500 points connected by straight lines in real time. These points must 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 embankment 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 feature:
-positioning the receiver (phone screen) by the Sun for easy orientation on the terrain [1];
-cylindrical coordinates (azimuth(), distance(r) to the previous point, difference in elevation between the points(z);
-editing coordinates manually (and therefore recalculating) P, Lat,Lon, H P X Y Z;
-exporting the surface to autocad (you just need to drag the script generated by the application from the Explorer to the autocad workspace and automatically draw the surface from 3D faces) https://youtu.be/gxceDyb0Bjo;
-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)

location may use sources like Wi-Fi, mobile networks, and sensors - this reduces the accuracy of measurements - for this reason: settings > location > Google Location Accuracy> Off


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.
[1] - 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 asterik coincides with the Sun )
