High Level Model

Deviation Survey, at a high level, is composed of a series of points (also referred to as stations). Each of these points has a series of corrections associated with it in order to calculate, with some degree of certainty, the exact position of the point.

The information regarding the action of performing a deviation survey are captured in the class Deviation_Survey_Acq.

A deviation survey can have many thousands of points associated with it. In some cases, the engineer may create a Decimated Survey, which would be composed of a subset of the available data. For example, the engineer may choose to have only every tenth point. In this case, the parent survey is the survey that contains all the points.

The Status of each point, along with the time that it changed status and the reason why it changed status, is captured in the Survey_Point_Status class with the reference list of statuses held in R_Survey_Point_Status.
