== Purpose ==

Get together project members to make decisions and tackle larger problems (as done last year at the [[Toronto Code Sprint 2009]]). This code sprint is targeting members of the "C Tribe" (eg, Mapserver, GRASS, GDAL, Proj, PostGIS, MapGuide). Other tribes are welcome to join the sprint, of course, but we hope that "C Tribe" members will give this event special consideration.

We have started a [[New York Code Sprint 2010 Agenda]] page for preliminary planning of tasks.

== Timing ==

Dates: February 20 to 23, 2010.

Duration: Four days (Saturday to Tuesday) from approximately 9am-4pm

== Venue ==

The Open Planning Project and OpenGeo will be hosting the event this year, in a penthouse event room ([http://www.flickr.com/photos/philaestheta/3922525728/in/set-72157622375114194/ pic1], [http://www.flickr.com/photos/92995391@N00/4081335110/ pic2], [http://www.flickr.com/photos/92995391@N00/4080572085/ pic3], [http://www.flickr.com/photos/92995391@N00/4080570151/ pic4]) on the top floor of their offices ([http://maps.google.com/maps?q=148+Lafayette+Street+new+york Map]), providing us a beautiful space and free internet access for the duration.

148 Lafayette Street 
New York, New York 
10013, USA 
Telephone: 212.796.4220 

=== Weekend Access ===

Access on the weekend will be complicated due to the main lobby being locked. If you leave the venue, remember to '''bring your cellphone''' so you can call up to get let back in. '''Call or text Paul @ 1-555-555-5555'' if you find yourself locked out.

== Sponsors ==

We will again be looking for sponsors ($750) to support food and fun for the sprinters as they work hard and play hard for four productive days. Each $750 sponsorship will be put towards lunch and dinner costs for the sprinters, and potentially bringing in sprinters who might otherwise be unable to attend.

To sponsor, please contact Paul Ramsey (pramsey at cleverelephant dot ca) directly.

== Individual Preparation ==

* Bring your own computer
* Install subversion and the compiler tools, and come with a working development environment if possible.

* Is the New York Code Sprint just a coding event?
** Yes, a coding and documentation event. It is a working session for people who are already participants in open source projects.
* Will it be possible to present new projects during this event?
** No, this is not a presentation-oriented event. People will get together in small groups and work on areas of mutual interest within their projects.

Wiki-Alanflrida: /* Standard MetaCRS Test Data Files */

'''NOTE: This document has migrated to the MetaCRS Trac Wiki, and is now at: http://trac.osgeo.org/metacrs/wiki/WikiStart'''

------

== Background ==

MetaCRS is a project encompassing several projections, and coordinate system related technologies. Our plan is to treat a variety of coordinate system activities as one Project from an OSGeo point of view. This helps provide enough "project mass" to justify the full OSGeo project treatment. But more importantly it would give us a forum to cooperate. Sharing things like coordinate system dictionaries, test suites and mathematical formulations.

== Project Steering Committee ==

The project steering committee consists of the following individuals and operates according to the [[MetaCRS PSC]] procedures.

* Frank Warmerdam (chair)
* Hugues Wisniewski
* Norm Olson
* Mike Adair
* Howard Butler
* Martin Davis

== Sub-projects ==

The following are sub-projects of MetaCRS:

* [http://trac.osgeo.org/proj PROJ.4] - lead - Frank Warmerdam
* [http://trac.osgeo.org/proj4js Proj4js] - lead - Mike Adair
* [http://trac.osgeo.org/csmap CS-Map] - lead - Hugues Wisiewski
* [http://geotiff.osgeo.org/ GeoTIFF/libgeotiff] - lead - Frank Warmerdam
* [http://spatialreference.org/ SpatialReference.org] - lead - Howard? Chris?
* [http://trac.osgeo.org/proj4j/ Proj4J] - lead - Martin Davis

== Commiters ==

Commiters are technically able to commit on any part of MetaCRS but traditionally they have sub-projects on which they focus, and they will avoid commits on other sub-projects without discussion with the project lead. New commiters may be [https://www.osgeo.org/cgi-bin/auth/ldap_group.py?group=metacrs added] after a vote of the PSC.

* Howard Butler (hobu): libgeotiff, spatialreference.org
* Hugues Wisiewski (hugueswski): CS-Map
* Mike Adair (madair): Proj4js
* Norm Olsen (normolsen): CS-Map
* Paul Ramsey (pramsey): libgeotiff
* Frank Warmerdam (warmerdam): PROJ.4, libgeotiff
* Chris Schmidt (crschmidt): spatialreference.org
* Richard Didier (drichard): PROJ.4
* Martin Davis (?): Proj4J
* Landon Blake (surveyor): Proj4J, testsuite
* Martin Desruisseaux (desruisseaux): testsuite

== Mailing list ==

In order to facilitate further discussion I have created a mailing list. Please join if you have an interest.

http://lists.osgeo.org/mailman/listinfo/MetaCRS

== Practical Questions ==

Answers are not authoritative - they are one opinion on possible answers.

=== Are we trying to merge the source into one super-library? ===

No, though there may be opportunities that arise for consolidation over time.

=== Is my library/component going to be subject to the whim of other contributors? ===

I imagine we will want to use the ''lieutenant model'' of development where particular components are essentially maintained by a chief maintainer. The project steering committee would establish broad policy (such as contributor rules) and facilitation for shared components (perhaps some dictionaries) while leaving technical direction of some components to their primary maintainer (ie. Norm for CS-Map).

=== So will all these packages live in a single subversion repository with a single Trac instance? ===

The current plan is to use a single SVN repository for MetaCRS projects (http://svn.osgeo.org/metacrs) with distinct subtrees for each project. But each project has the option of it's own distinct Trac instance - for example http://trac.osgeo.org/proj and http://trac.osgeo.org/proj4js.

=== What are Java developers doing on the mailing list? ===

The Java developers come from a range of projects; and are very interested in geeking out about correctness and accuracy issues. There are also a couple opportunities for collaboration (shared testing scripts and the like).

We will seek close cooperation with a variety individuals and organizations interested in interchange of spatial reference system descriptions, and related standards including other open source projects, organizations like OGC, national mapping agencies, and proprietary software developers.

== Non-Programming Collaboration ==
What opportunities are there for collaboration with projection libraries in languges that are not directly compatable with C programming language or C++ programming language libraries? (For example: GeoTools includes functional code for spatial reference systems in Java based on the ESPG database.)

Suggestions:
* Common Spatial Reference System or Coordinate Reference System Names and Descriptions
* Coordinate System (and CRS related object) dictionaries. Stuff like the EPSG dictionary.
* Datum shift lists (towgs84), and datum grid shift files (NTv1, etc).
* Transformations, calculations, and algorithms written in pseudocode that can be edited in different languages.
* Descriptions of spatial reference systems that can be used by developers in different programming languages.
* Notes on transformation from different representations of a CRS (WKT, PROJ.4, GCTP, GML,...).
* Test suites with test points in a variety of coordinate systems and their lat/long and WGS84 equivelents).
* Articles on spatial reference systems and translations useful for programmers interested in spatial reference system implementations. For example:
** Understanding The Difference Between National Vertical Datum of 1929 and the North American Datum of 1988

== Standard MetaCRS Test Data Files ==

Work has begun on a set of standard test data files that can be used to verify the coordinate transformations/conversions performed by
the various OSGeo projects that fall under the MetaCRS umbrella. You can learn more on the [[Standard MetaCRS Test Data Files]] wiki page. [http://www.dissertationwritinghelp.co.uk/ Dissertation Help][http://power-scooters.com/ power scooters] [http://www.logoinn.com/ Logo Design]
