Subject Re: Spatial session at Apache: Big Data North America - Call for interest
Date Fri, 13 Nov 2015 16:11:52 GMT
It good to see the comments of interest in a spatial big data session.

The combination of Open Source, Open Standards and Open Data is very rich and productive in
the geospatial community.

A focus on the topic at Apache Big Data NA aims to extend that synergy into the area of geospatial
search and analytics at scale.

  Several Apache projects are implementing geospatial functionalities and there is an opportunity
to discuss approaches.   One opportunity is to consider the use of open standards to increase
interoperability and code reuse.  Relevant standards include ISO 19115 for geospatial metadata.
OGC standards include Simple Features, coordinate reference systems and WKT, GeoSPARQL. coverages
and DGGS.
>> Relevant projects include Accumulo, SIS, Marmotta, Solr, Tika, Magellan, NiFi, others.
>> Supporters of this spatial session include:
>> George Percivall, OGC
>> Chris Mattmann, JPL/NASA
>> Martin Desruisseaux, Geomatys
>> Sergio Fernández, Redlink
>> Ram Sriharsha, Hortonworks
