-------------------------------------
Resolution: Fixed
> Support spatial referencing by geographic identifiers (ISO 19112)
> -----------------------------------------------------------------
>
> Key: SIS-352
> URL: https://issues.apache.org/jira/browse/SIS-352
> Project: Spatial Information Systems
> Issue Type: Task
> Components: Referencing
> Reporter: Martin Desruisseaux

> Provide a basic support of [ISO 19112:2003 — Spatial referencing by
> geographic
> identifiers|http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=26017].
> Geographic identifiers are location descriptors such as addresses and grid
> indexes. ISO 19112 describes (among other things) how to map geographic
> identifiers to spatial coordinates. Some keys classes defined by ISO 19112
> are listed below (Apache SIS would not necessarily use exactly the same
> names):
> * {{SpatialReferenceSystemUsingGeographicIdentifier}}
> * {{Gazetteer}}
> * {{LocationType}}
> * {{LocationInstance}}
> The {{Gazetteer}} seems the most interesting part for us, since it is the
> class in charge of converting a geographic identifier to something else
> (_e.g._ a geographic coordinate). It seems that {{Gazetteer}} could be
> compared to the {{MathTransform}} interface that we already implement in the
> following package:
> * {{org.apache.sis.referencing.operation}}
> but working on geographic identifiers instead than coordinates. For this
> reason, I propose to put an ISO 19112 implementation in the following package:
> * {{org.apache.sis.referencing.gazetteer}}
> I have hesitation about whether such package should be in a separated module
> (e.g. {{"sis-referencing-by-identifier"}}) or not, but given that I expect
> the amount of classes to be small I'm not sure it is worth creating a new
> module.
> An implementation of [Military Grid Reference System
> (MGRS)|https://en.wikipedia.org/wiki/Military_Grid_Reference_System] is used
> for experimenting what the API may looks like. Despite its name, MGRS is not
> used only for military purpose. It is used also as a way to organize Earth
> Observation data on Amazon S3 cloud storage.
> Note that Apache SIS already have (since the 0.1 version!) a class that seems
> in the scope of ISO 19112:
> [GeoHashCoder|http://sis.apache.org/apidocs/org/apache/sis/index/GeoHashCoder.html].
> As part of an ISO 19112 support, we could also refactor {{GeoHashCoder}} as
> another implementation, side-by-side with {{MilitaryGridReferenceSystem}}.
