Surveyor is a measurement application running on a smart phone. It has the characteristics of accurate calculation, easy and efficient, intelligent and convenient. Surveyors can be used in roads, bridges, railways, tunnels, subways, municipal works, etc. Except for the functions of tunnels and subways, the functions of other projects are free, and the online measurement function is also free. The software is stable and accurate in basic calculations and supports the following features:
Multiple lines can be established, independent of each other, and quickly switched.
Supports broken chains, including long chains and short chains.
It supports two types of flat curve input methods, the intersection method and the line element method, and supports various linear routes, such as ramps, oval curves, turning curves, and S-shaped curves. Supports multiple flat curve calculation methods, such as commonly used calculation expansions (6 terms), Gaussian 5-node integrals, etc.
The vertical curve supports not only the point of slope change, but also the point of polyline, which has wider applicability.
The standard cross section adopts the concept of plates, and each plate has independent superelevation, widening, and strong applicability. There are multiple gradients for super height and widening: linear, cubic parabola, and quadratic parabola.
Tunnel sections and slope sections support direct import of CAD section views, eliminating the complexity and annoyance of editing sections.
Support for subway tunnel offset
The tunnel is supported to rotate with the super-high full section and local cross-slope section.
It supports online total station measurement, which is efficient, time-saving and easy. The currently supported instruments are: Leica, Topcon, Nanfang, Sojia, Sanding, Su Yiguang, Pentax, Zhongwei, Kelida, Nikon, Kewei, Bofei, Ruide, Zhonghaida.
Supports online RTK, supports instruments that can enter NMEA-0183 format, and can be used as a substitute for handbook to stake out after online.
Supports calculation of coordinates for any mileage, any offset, and any included angle.
The coordinate back calculation of the station number supports the calculation of multiple solutions in complex lines, without the need to enter nearby mileage, and the algorithm is complete.
Supports graphical staking, which is more intuitive and easier to check for errors.
Support batch calculation and export to Excel, TXT.
Support record function, you can export the stake out record to Excel, TXT.
Support tunnel section scanning to export CAD drawings, instead of section scanners, set up stations at any point, without computer post-processing, and produce CAD drawings directly from mobile phones.
Support calculation of structures such as culverts and pile foundations.
There are simple, advanced coordinate inverse calculation tools.
Supports importing easily measured system parameters.
Icon support drag sort, hide infrequently used icons
Support calculation of metro segment attitude and shield machine attitude
