Deviation Survey Data

In addition to the data being held in a relational form, the data can also be stored in its raw form and/or as a bulk array of data. If there is a requirement to store either the raw magnetic or gravitational readings, then they can be held in the class Deviation_Survey_Point_Raw.

The status of a point can change over time as it is interpreted, rejected, or approved and ultimately released for use. This information is stored in the Survey_Point_Status class, which is an extension table to the Deviation_Survey_Point class.

For some applications, it is also beneficial to store the whole survey in a binary format. If this is the case, the data for every point in the survey is combined into one binary object and stored in the Bulk_Array table
