Vertical Curves app for iPhone and iPad

This app was designed to calculate equal and unequal tangent vertical curves. It uses a simple interface to make it easy to input known vertical curve information.

This app calculates Sag, Crest, Uphill and Downhill vertical curves based upon the information shown on typical engineering drawings.

- Calculate the High and Low point for Sag and Crest curves.
- Calculate the elevation for any station value.
- Calculate the station value given a elevation along the curve.
- Calculate all station and elevations for any interval.

There are many different codes to chose from, some are required and others are optional.

Works in Feet or Meters.

This app is a companion to the book "Vertical Curves" in the math series "Surveying Mathematics Made Simple".
