Re: Apache 2016 Geospatial Track - results in Big Geo Data white paper

[Martin Desruisseaux <ma...@geomatys.com>]

Hello Georges

Thanks for the paper, it is interesting. Of course I support the
proposal for a new geospatial track in ApacheCon 2018 and hope to
participate too.

Section 4.2 (Cloud computing for EO data) mentions the lack of common
API for interacting with the clouds. The section enumerates
authentication, billing, etc. as examples of services for which there is
no common API, but maybe we could add map projections, coverages access
methods, etc. to that list if we envision that some companies may offer
clouds specialized in geospatial data? This section cites web services
(WMS, WCS, WPS) as a common API, but for simple processes like a map
projection, the encoding and decoding parts can count for 90% of the
total execution time. It is possible to avoid that cost in some
situations by standardizing an API at the programming language level, in
addition to web APIs. Inconvenient is that the way to transfer data
become more language-dependent. It would be possible to produce a proof
of concept in OGC test bed 14 as a side-effect of proposed topic on map
projection validations.

Note: I think there is a minor typo in the link to "Big Data from Space
2106 conference"; I presume the intended year was "2016"?
