9. Conclusion

The set of GPS specifications, comprising dimensional, geometric, surface condition, and transition specifications, gives specifiers considerable latitude to express their functional requirements, incorporating modifiers where necessary. It is therefore important that they are familiar with the coding system and that those interpreting these requirements, as indicated on the specified plans or 3D models, understand them according to a given normative reference system (in this case, the ISO GPS system), i.e., that everyone is speaking the same language.

To enable increasingly detailed expression of functional requirements, standards are evolving to complement current capabilities and harmonize the language as a whole, hence the importance of monitoring standards in this area.

It therefore seems natural that ISO GPS specifications should be...
