About Field Codes

In the field, you use field codes to distinguish the points that you measure. For example, field code B10 represents a control point, field code LM21 represents a building corner, and field code WW41 represents a manhole. The field code is an alphanumeric value with a maximum of 64 characters.

You use field code lists to map the measured points to industry model feature classes. You assign the field code list to a project, so that several calculation projects can use the same field code list.

The field codes connect the field measurements to the database. The field code controls how the measured points are introduced into the calculation process, how reference points are searched, and into which document/feature class a new point will be distributed.

• Existing points are base points and reference points that already exist in the database. For each field code, you specify search rules and tolerances.
• Identical points are points that have been measured more then once. For each field code, you specify search rules and tolerances.
• New points can be distributed to multiple target documents. For each field code, you specify the document, the feature class, distribution rules, and optionally up to 10 pairs of attribute/value combinations.

Survey provides a Field Code Manager to manage multiple field code lists. See also Field Code List Manager.
