Dear Scott,

Thank you very much for your answer and sorry for the delay of my reply.

I have been discussing with my colleagues internally and we are considering the possibility of working within the OGC DGGS framework to come up with a Postal-specific standard being develop that could define the minimum requirements or the actual mapping process between postal addresses and grid systems, as you suggested. I am not sure however that we could or be interested in developing a neutral reference grid to which other grid could be mapped but more as I mentioned just right before, establish the principles, characteristics, minimum requires or whatever is needed for the interoperability of the grid systems used in absence or as a complement of traditional postal addressing systems. Somehow on a similar way it was done with ISO TC 211 Addressing 19160 and its part-4.

Do you have any information that you could help us to have a better idea on the OGC working methods and what will be expected from us if we go for it?

Thank you in advance,

With my best regards, ,

Patricia Vivas

Dear Patricia,

Thank you for your comments. Unfortunately, we are not able to extend the public comment period in advance of voting on this candidate Abstract Specification Topic. You are still welcome to provide comments in the coming weeks as the comments may be considered in the text as it undergoes final revision prior to publishing.

I will make one clarification that might suit your use case well. The OGC DGGS standard is being considered as an Abstract Specification Topic. As such, it would form a foundational element from which implementation standards could be built. I can see the value of a Postal-specific implementation standard being developed that could define the mapping between postal addresses and grids and perhaps develop a neutral reference grid to which all other grids could be mapped.

I appreciate your contact and look forward to further comments or ideas.

Thanks and Regards,

Scott Simmons

In response to the request for public comment on its Discrete Global Grid System Abstract Specification Topic, the Universal Postal Union (UPU), as specialized agency of United Nations in charge of postal issues, would like to contribute to this document with comments. However due to various external factors, it would be very difficult to provide you with our comments within the time limits.

Nevertheless the UPU reminds interested in the topic for several reasons.  On the one hand, the UPU is actively involved in the development of postal addressing, including postcodes. At the UPU we know that providing an address for everyone remains a challenge. On the other hand, during the last decade with the advent of internet and communication through electronic networks and more recently with the generalization of the use of maps and coordinates, we have witnessed an evolution in the way in which addresses are generated and used. The increase use of geographic information systems (GIS) have resulted in recent years in the invention of numerous new means for geo-coding / geo-locating points more quickly and at a much lower cost than heretofore possible using traditional addressing systems. However, these grid systems (actually called Discrete Global Grid Systems) do not generate addresses properly speaking, as per addressable object, but uses a hierarchy of equal area tessellations to partition the surface of the Earth into grid cells, and do not identify an object as addresses do, but a cell on the ground. These grid systems are meant to be used with devices, which could limit the use and access of such systems by the population in general. We should remind at this point that the UPU White paper states that address infrastructures are global public goods, which means that should be non-rival and non-excludable. Furthermore, these systems use algorithms to translate coordinates into geo-codes which are often not open sourced and not free of use for the user, especially for international bulk mailers or international logistics companies. Finally these grid systems are not interoperable and often incompatible at international level  from a purely postal point of view.

In view of the above, the UPU would like to know if there is a possibility for an extended deadline for submission of comments.

I look forward to hearing from you soon.

With our kind regards,

Patricia Vivas


OGC seeks public comment on new Abstract Specification Topic for Discrete Global Grid Systems (DGGS)

6 March 2017: The Open Geospatial Consortium (OGC®) is requesting public comment on its Discrete Global Grid System (DGGS) Abstract Specification Topic.
DGGS enable rapid integration of spatial data without the difficulties of working with legacy coordinate systems, particularly projected coordinates such as Universal Transverse Mercator (UTM). DGGSs represent the Earth as a hierarchy of equal area cells with progressively finer spatial resolution. Individual observations can be assigned to a cell corresponding to both the position and size (or uncertainty) of the phenomenon being observed. DGGSs provide significant benefits when encoding, scaling, threading, streaming, combining, and analysing spatial data.
DGGSs are characterized by the properties of their cell structure, geo-encoding, indexing strategy, and associated mathematical functions. The OGC DGGS Abstract Specification supports the specification of standardized DGGS infrastructures that enable the integrated analysis of very large, multi-source, multi-resolution, multi-dimensional, distributed geospatial data. Interoperability between OGC DGGS implementations is anticipated through implementation standards, and extension interface encodings of OGC Web Services.
OGC Abstract Specifications provide a conceptual foundation for the development of implementation standards. The intention of OGC’s DGGS Abstract Specification is to provide the geomatics and decision-making community with a formal document with which DGGS can be recognized, designed, built and used. The Abstract Specification defines the framework components that make up a compliant DGGS and the variability within those components.
The DGGS standard is available for public review and comment atportal.opengeospatial.org/files/72475<http://mail.opengeospatial.org/lists/lt.php?tid=fR4IAAFSBFFfWh1UVgxRSFBSUgQZCQJdVhkNV1IHDw8FAQkDXQZKUwICAwFRCVBIUAUDURkEB1JXGVsAB1sVBQNVBVIAWlAABVIAGVALVlJdVgcEGVIJBlQZDQcFUhUPBFsIGVZbBQZTUQkBBwpTBw>. Comments are due by 5 April 2017 and should be submitted to requests at lists.opengeospatial.org<mailto:requests at lists.opengeospatial.org>.
About the OGC
The OGC is an international consortium of more than 525 companies, government agencies, research organizations, and universities participating in a consensus process to develop publicly available geospatial standards. OGC standards support interoperable solutions that "geo-enable" the Web, wireless and location based services, and mainstream IT. OGC standards empower technology developers to make geospatial information and services accessible and useful with any application that needs to be geospatially enabled.
