Hello all
While we are waiting for the wiki (thanks Adam for forwarding the email
to infra), below is a first draft of an abstract proposal to the Apache
conference (Denvers, April 7-9). The deadline for submission is Friday
night, this week. Do peoples feel okay with that?
Submission type: Presentation
Category: Developer
Abstract:
--------------------------------------------------------------------
Apache Spatial Information System (SIS) is a Java library for developing
geospatial applications in close conformance with international
standards. SIS implements interfaces derived from the UML published
jointly by the Open Geospatial Consortium (OGC) and the International
Organization for Standardization (ISO). This presentation will introduce
why standards matter, OGC vision, the GeoAPI approach, Apache SIS
implementation and its roadmap. This first SIS presentation will focus
on metadata (ISO 19115) and referencing by coordinates (ISO 19111). We
will give a quick introduction to geodesy (did you knew that specifying
latitude and longitude is not sufficient for uniquely identifying a
position on Earth?) and see how existing resources can handle part of
the complexity for the developers.
Who the audience is and what we expect them to get:
--------------------------------------------------------------------
The audience is anyone who wish to handle geographic data in their
product and would like to familiarize with such topic. Attendees can
expect a big picture of standardization efforts, identify where some of
the complexity stands and how to hide it. In particular we will compare
the impact on complexity between using the XSD available on-line or the
UML as the source for application programming interfaces. Finally,
attendees can expect an overview of test suites that may help them to
increase their confidence in the georeferencing performed by their product.
How the content may help better the Apache and open source ecosystem:
--------------------------------------------------------------------
Geospatial data are ubiquitous, but the difficulty of handling them
accurately is very often under-estimated. Many applications just handle
latitudes and longitudes without realizing their ambiguity. This
presentation will hopefully help to improve awareness about standards,
encourage participation to implementation-neutral efforts like OGC works
and GeoAPI interfaces, encourage existing products to test themselves
against available test suites, and encourage participation to the
improvement of those implementation-neutral test suites. Then we hope to
raise interest in Apache SIS as one powerful implementation of the above.
