Paris Code Sprint 2016 : PostGIS Agenda

2016-02-25T10:46:56Z

Wiki-Pnorman: /* Possible PostGIS function improvement and addition */

Discussion and group review topics for the [[Paris Code Sprint 2016]].

== Discussion ==

* Clustering functions: Aggregate or Window?
** What naming convention
** What to do with the existing aggregate functions
* [http://www.postgresql.org/message-id/20178.1423598435@sss.pgh.pa.us Expanded object headers], introduction and testing
** How they work
** Potential advantages, disadvantages
** Discussion on clean implementation possibilities
** Testing and benchmarks, is it worth it?
* Alternate storage formats, beyond GSERIALIZED
** Reasoning
** How to add (version flags?)
** Multiple co-existing formats?
* Breaking raster out as postgis_raster extension (hold off on talking about this until Regina comes)
** Implications / difficulties
* GEOS improvements that would help PostGIS
* Way to know/be sure a geometry is valid, without need to launch an IsValid test (SFCGAL initial purpose)
* Using FDW with PostGIS (hold off on talking about this until Regina comes)
** Functions pushdown
** Current limitations
* PostgreSQL improvements that would help PostGIS
** Parallel query, review experiments, plan and execute more (hold off on talking about this until Regina comes)
** Feed back parallel query results to pgsql-hackers
* [https://github.com/postgis/postgis/pulls Open pull requests from GitHub]
** Merge, modify, or reject
* Tickets with design implications
** https://trac.osgeo.org/postgis/ticket/2529
** https://trac.osgeo.org/postgis/ticket/3405
** https://trac.osgeo.org/postgis/ticket/3246
** https://trac.osgeo.org/postgis/ticket/3326
* Do we want to bundle example datasets w/PostGIS for docs, tutorials?
* Adding more checks to automated builds?
** valgrind (would need to add suppressions for GEOS leaks)
** gcov (identify untested or unused code paths)

== Tasks ==

* Benchmarking of expanded object headers test branch
* Benchmarking of parallel query and parallel aggregate work from pgsql-hackers

* BRIN indexes implementation for PostGIS geometries
* postgis/lwgeom_in_* move to liblwgeom dir (or any code that doesn't depend on Postgres?)

== Possible PostGIS function improvement and addition ==

* improvement
** <s>st_pointN -> make a negative input count backward [rémi]</s>
** <s>st_setPoint -> make a negative input count backward [rémi]</s>
** <s>st_asText -> optionnal arg to limit digit number [marc]</s>
** <s>st_centroid -> work on circular string (simply dump points, then classical centroid) [remi] </s>
** st_exteriorRing -> make it work on multipolygon, returns a collection
** <s>st_makeline -> make it work on multipoints [pauln]</s>
** st_scale -> optionnal argument to define the center of scaling (allows to scale "in place") [marc]
** st_split -> allow splitting (multi)line by (multi)point
** st_asgml -> allow GML 3.2.1 support (not only namespace handle) http://portal.opengeospatial.org/files/?artifact_id=26765
** st_asgml (and st_geomfromgml) -> handle gml:Envelope
** ST_AsX3D -> Bug fix - how to determine if 3D geometry is convex without resorting to CGAL. http://trac.osgeo.org/postgis/ticket/3435
** ST_GeogFromText -> make the longitude swap 180 deg when entering a latitude over 90 (postgis already counts the latitude backwards from 90 when crossing)
* slight addition
** st_angle(P1,P2,P3) [remi]
** st_MakeRing((multi) linestrings and/or points
** st_DumpLines -> dump everything to line (rings in poly, lines in multilines, etc. )
** st_DumpSegments -> dump segments (in the mathematical sense), that is every consecutive pairs of points in lines
* big addition
** generate grid (regular and hex)
** st_snapToLine -> st_snap = snap vertex to vertex. This one = snap vertex to vertex or edge. (note: st_snap also snap line to vertex)
** st_splitLineByPoint(line,point,tolerance) -> using curv absc, the only current way to not be sensible to precision issue (st_split doesnt work)
** st_VariableBuffer(geomM) -> buffer on geometry, the radius is given by M of each vertex, linear transition between. A lots of uses
** St_FindCurve(geom,radius_range,min_number_of_support_points,tolerance) -> in a classical geometry, find the point describing arcs
** St_MakeArc(P1,P2,centre) and St_MakeArc(P1,P2,radius) -> create arcs (_not_ using 3 points on arc!)
** St_OrientedBBox(geom) -> returns the oriented bbox of the geom (returns a geom and an angle)
** ST_KMeans -> window function - pramsey to integrate into 2.3 code base - https://github.com/pramsey/postgis/tree/kmeans

== Purpose ==

Bring together project members to make decisions and tackle larger geospatial
problems as in previous years:

* [[Philadelphia Code Sprint 2015|Philadelphia]] (2015)
* [[Vienna Code Sprint 2014|Vienna]] (2014)
* [[Boston Code Sprint 2013|Boston]] (2013)
* [[IslandWood Code Sprint 2012|Island Wood (Seattle)]] (2012)
* [[Montreal Code Sprint 2011|Montreal]] (2011)
* [[New York Code Sprint 2010|New York City]] (2010)
* [[Toronto Code Sprint 2009|Toronto]] (2009)

== Dates and Times ==

Dates:
* Welcome event: evening of Mon, Feb 22 (see below)
* Sprint: Tues, Feb 23 - Fri, Feb 26 (4 days), from 9h30 till 19h00

== Place ==
* 16bis Boulevard Montmartre, 75009 Paris - Mozilla Foundation
* https://www.openstreetmap.org/node/2883451098
* Metro: Grand Boulevard or Richelieu Drouot

'''To be noticed: For security reason, you have to be registered (on this Wiki page) to be allowed to enter in Mozilla place.'''

We could use three kind of spaces:
# The main code sprint room (with seats and tables, video projection, paperboard)
# A "bar" room, just beside the main one (for meals, breaks, T-Time...)
# Meeting room (allowing group to talk without making too many noise in the main room)

Few rules to follow:
# Keep in mind to carefully close Mozilla outside door (aim is to not allow any outsider to get in).
# No meal, nor drink in the main sprint room (plain water is tolerated).
# Don't waste Internet bandwith (as we share all the same Wifi connection).
# Food and drinks are available in the bar room, you could use freely OSGeo ones (but not Mozilla ones).
# As others events could be organized on evening, we could so be asked to tidy the main room before we leave.

== Logos ==

Sylvain Beorchia will be on the sprint on D3 (Thursday), with a graphic design focus.

(He designed this Code Sprint logo, yeah the chicken one,
and this other OSGeo event one http://osgeo.asso.fr/foss4gfr-2016/ or Oslandia logo among others... )

If you’re interested to got a (new) clean and fresh logo for you project, just say it so:

== Communication ==

* Please join the mailing list: http://lists.osgeo.org/mailman/listinfo/tosprint
* IRC chat during the event: #tosprint Server: irc.freenode.net
* Twitter: #TOSprint ( https://twitter.com/search?q=tosprint )

== Photos ==

* On Flickr thanks to use, as tag name, for Code Sprint photos: ''ParisCodeSprint2016''

* If you want to play, we also open a Paris urban photos contest. Weird and arty points of view are welcome ! On Flickr tag is: ''ParisCodeSprint2016Urban''

== Costs ==

Participants should plan for the following costs:

* Travel to Paris
* Accommodation for four nights (including breakfast)

All other costs - food, outings and entertainment - should/will be covered by the sponsors

== Hotel and co ==

Center of Paris is indeed quite small, the sprint place quite central, and metro network quite dense. 
So no special need to be that close from the sprint place (anywhere else in Paris could also be fine, with less than 30-45' by tube).

However, nice hotels, quite close to the sprint place:
* http://www.astotel.com/hotel/hotel-le-34b/overview
* http://www.hotel20prieure.com/

A common way to find a discounted room in Paris is to use: booking.com

Paris is also well known to became an AirBNB city. 
Could be so a way to share (big) flat, among some sprinters.

And there's also hostels, for those who want/need to find a cheaper hosting solution.
* http://www.hostelworld.com/Paris

== Individual preparation ==

* Bring your own laptop
* Install GIT and compiler tools, and come with a working development environment
* For North American folks take an European power adapter, for Swiss and Italian ones depends on ground slot ( http://wikitravel.org/en/File:Plugs.png )
* If your laptop need it, video export adapter to DVI and/or VGA
* Optional: something to take pictures (camera, smartphone, small tablet...)

== Sponsors ==

We have three sponsorship levels:

* Gold: >= 2500 €
* Silver: 1500 €
* Bronze: 750 €

We encourage sponsors to support nutriment and entertainment for the
sprinters as they work hard and play hard for four or five productive days.
Contributions will be put towards lunch, snacks, and dinner costs for the
sprinters, and potentially bringing in sprinters who might otherwise be unable
to attend. Any surplus at the end of the event will be turned over to OSGeo or
used for a future code sprint.

Sponsors will receive the following honors:

* Your logo at the top of this page
* Mention in all of our public communication
* Our undying gratitude, which comes in handy when you least expect it (Remember that feature you wanted...)
* And as extra, for Silver and Gold: Kakemono in the event room (if you provide it)

To sponsor, please contact Olivier Courtin (olivier dot courtin at oslandia dot com) directly.

== Communication ==

* Please join the mailing list: http://lists.osgeo.org/mailman/listinfo/tosprint
* IRC chat during the event: #tosprint Server: irc.freenode.net
* Twitter: #TOSprint ( https://twitter.com/search?q=tosprint )

== Costs ==

Participants should plan for the following costs:

* Travel to Paris
* Accommodation for four nights (including breakfast)

All other costs - food, outings and entertainment - should/will be covered by the sponsors

== Hotel and co ==

Center of Paris is indeed quite small, the sprint place quite central, and metro network quite dense. 
So no special need to be that close from the sprint place (anywhere else in Paris could also be fine, with less than 30-45' by tube).

However, nice hotels, quite close to the sprint place:
* http://www.astotel.com/hotel/hotel-le-34b/overview
* http://www.hotel20prieure.com/

A common way to find a discounted room in Paris is to use: booking.com

Paris is also well known to became an AirBNB city. 
Could be so a way to share (big) flat, among some sprinters.

And there's also hostels, for those who want/need to find a cheaper hosting solution.
* http://www.hostelworld.com/Paris

== Sponsors ==

We have three sponsorship levels:

* Gold: >= 2500 €
* Silver: 1500 €
* Bronze: 750 €

We encourage sponsors to support nutriment and entertainment for the
sprinters as they work hard and play hard for four or five productive days.
Contributions will be put towards lunch, snacks, and dinner costs for the
sprinters, and potentially bringing in sprinters who might otherwise be unable
to attend. Any surplus at the end of the event will be turned over to OSGeo or
used for a future code sprint.

Sponsors will receive the following honors:

* Your logo at the top of this page
* Mention in all of our public communication
* Our undying gratitude, which comes in handy when you least expect it (Remember that feature you wanted...)
* And as extra, for Silver and Gold: Kakemono in the event room (if you provide it)

To sponsor, please contact Olivier Courtin (olivier dot courtin at oslandia dot com) directly.
