10. 10 1. Data standardization and architecture National characteristics: Culture, Language, Procedure, admin, Code National standardization for land systems and data under a common technological platform with interfacing capabilities are prerequisite to generation, integration, transaction, connectivity, and sharing and information service. It should be a part of National information Standardization and follow the parent regulation and rules of the nation Case of ONEMAP Indonesia Data Standardization
