Comment Period Open for GeoPackage Specification Draft

The Open Geospatial Consortium (OGC) has published a draft GeoPackage specification for comment. The GeoPackage specification attempts to create a non-proprietary means for packaging and exchanging all geospatial data in all its forms (vector, raster, and tiles). A couple of things that jump out at me:

  • It calls out SQLite as the reference implementation of a GeoPackage container
  • It calls out SpatiaLite 4 as the reference implementation of a vector feature store
  • It does not call out a reference implementation for rasters or tiles
  • It does not mention exchange of cartography.

Getting Ready for JS.geo

I’m looking forward to next week’s JS.geo event in Denver. It is a small event, spearheaded by Chris Helm of Esri, that focuses on the use of Javascript in geospatial applications. Although I have been more vocal in my recent explorations with Python, I’ve probably done as much, if not more, work with Javascript over the past 18 months.

SpatiaLite 4.1.0 Beta Preview Available

On the SpatiaLite Google Group this morning, Sandro Furieri announced the availability of a beta preview of SpatiaLite 4.1.0. The primary focus of this preview is to get early comment on new capabilities supporting the storage, validation, and query of XML documents.

More information about this update can be found here. Says Sandro:

The main goals of these recently introduced enhancements are:
– storing XML Documents directly within the DBMS
– supporting XML validation
– supporting plain SQL queries on behalf of XML Documents
via canonical XPath expressions

Implementing directly into the Spatial DBMS a common core of XML-oriented features surely is an interesting and useful option, just considering that ISO- and INSPIRE-Metadata or SLD/SE Styles are fully based on XML.

Although I find myself working more with GeoJSON and CartoCSS these days, I think support for XML is a good step for SpatiaLite. There are some very mature use cases based on XML, as Sandro points out. While SLD is not my favorite, this may keep it on my radar. Also, it would be interesting to see how this new capability would possibly affect the evolution of the OGC GeoPackage draft specification.

 

A GIS Day Map for World Diabetes Day

Today is World Diabetes Day. It also happens to be GIS Day so I thought a map (not mine) of new diagnoses would be in order:
