(v) The process of evaluating actions requested by the operator to determine if such actions resulted in invalid geometry. Depending on the system, error checking may be done automatically (such as when a file is saved to disk) or manually at the request of the user.

The process of examining input data to make sure it is both appropriate (within specified value or scalar ranges) and accurate (correctly reflects the input).

Process of testing transmitted or received data to ensure data integrity and to ensure the that the data meets all partner-specific requirements. The most efficient way to handle error checking is to use the chosen standard's dictionary for validation, then the mapping only has to evaluate that the fields that have requirements that are more restrictive than the standard, e.g. a field that is optional in the standard but required by one trading partner, or a field where the standard allows a certain number of characters but the a partner limits the use to fewer characters.

n. A method for detecting discrepancies between transmitted and received data during file transfer.
