Circular curve coordinate calculation program

The curve coordinate calculation program can calculate the center, edge pile coordinates and tangent azimuth of a circular curve with a transition curve. If you only need to calculate a circular curve, enter 0 for the transition curve.

​

Function introduction

1. This software can calculate the center and edge pile coordinates and tangent azimuth of circular curves with transition curves. If you only need to calculate circular curves, enter 0 for the transition curve.
2. It is equipped with forward calculation and inverse calculation functions. Forward calculation: calculates coordinates through mileage and offset, and inverse calculation: reverses mileage and offset through coordinates.
3. Data input: The curve angle α and the calculated azimuth angle F are input in d.ms format, for example: -14°18ˊ10″ is: -14.1810. When "continuous calculation" is selected, the offset and declination angle are the same as the single point calculation.
4. It has data import and export functions. You can enter known data into a text document for import, and export is to export the entered data to a specified location.
5. After the data processing is completed, click "Save Data" to save the five major curve piles and the curve parameter table. In the continuous calculation mode, "Save Data" can export the calculation results.
