An ideal vertical curve to join two gradients is a parabolic curve.

• A parabolic curve provides a smooth transition between two gradients

• It ensures a gradual change in slope, reducing the risk of sudden changes in elevation

• The length and radius of the curve can be calculated based on design standards and the specific site conditions

Hydrographic surveys deal with the mapping of underwater features and terrain.

• Underwater features such as the seabed, shorelines, and water depths are mapped.

• Data collected is used for navigation, marine construction, resource exploration, and environmental protection.

• Techniques used include sonar, GPS, and satellite imagery.

Diopter is the power of a lens having a focal length of 1 meter.

• Diopter is the reciprocal of the focal length of a lens in meters.

• It is used to measure the optical power of a lens.

• For example, a lens with a focal length of 0.5 meters has a power of 2 diopters.

The accuracy of fix by two point problem is dependent on the distance between the two points and the quality of the measurements taken.

• The accuracy of the fix increases as the distance between the two points increases.

• The accuracy also depends on the precision of the measurements taken at each point.

• Errors in measurements or inaccuracies in the data can affect the accuracy of the fix.

• Using more than two points can impr
