Changes：
1. Road cross section interpolation.
2. Registration code compatible upgrade.
3. Attribute export Excel with multimedia information.
4. Total station optimization.
1) When setting a station with known azimuth and known point, you can specify the azimuth and the horizontal angle of the circle respectively. The coordinate calculation uses the calculated azimuth, and the software displays the horizontal angle of the circle.
2) When setting the horizontal angle in the total station information, only the horizontal angle of the degree disk is set. If the station has been set, create a new station.
3) The station setting direction displayed on the map is the azimuth direction used for calculation.
5. List adaptation.
6. Optimization of renaming duplicate point names in text import.
7. Added input, menu, menu + input, menu + input + record history input in the attribute field input method.
