A Guide to the Role of Standards in Geospatial Information Management: Companion document on Standards Recommendations by Tier

This Companion Document describes which standards may be appropriate to use in each of the Tiers as identified in “A Guide to the Role of Standards in Geospatial Information Management”. This Companion Document provides guidance on geospatial standards that could be used at each Tier in the maturity model. The list of standards provided is not intended to mean that every standard is mandatory at each Tier. Instead, these are meant as recommendations. For example, a number of standards are listed for Tier 1. Of the list provided for Tier 1, an initial Spatial Data Infrastructure (SDI) implementation may only implement one or two of the suggested standards. Further, standards recommended in Tier 2 could be implemented in Tier 1 and vice versa. The final decision as to which standards are implemented must be based on specific requirements and use cases. The first three sections of this companion document recommend essential geospatial standards by Tiers as described in the “Guide to the Role of Standards in Geospatial Information Management”. This discussion is followed by a final section that discusses “foundational” standards that should be consulted. These foundational standards represent two categories of standards: - General information technology and Internet standards on which geospatial standards may be dependent. While not all of these standards may be required for implementation, they may be required within an implementing community’s operational environment. - General Geospatial Standards which include best practice standards regarding geospatial data definitions, representation, data quality, general architecture and other aspects of geospatial information and technology. They collectively provide guidance on geospatial data collection, production, and maintenance.
