The annual OSGeo Code sprint was held in Bonn March 18 to 25, bringing 
together nearly hundred members of the OSGeo community together.  A code 
sprint is a chance for the community to meet in person for direct 
collaboration, projects use this as an opportunity to work together or 
tackle larger issues as a team.

We made use of BaseCamp Bonn (http://www.basecamp-bonn.de/) to host the 
code sprint, providing a friendly indoor "campground' with picnic tables 
for working, surrounded by caravans of all shapes and sizes making up 
the accommodation. It can be quite a shock to roll out of bed, and find 
python developers in a cluster before your morning coffee.

Participation was open to all, not only OSGeo projects, and we were 
pleased to welcome over eighty developers from all over the world! This 
was a chance for developers to meet (often for the fist time) and 
collaborate with core developers, gaining a insight into the software, 
and participate in open source development,

An impressive list of projects was represented: uDig, GeoTools, 
LocationTech, JTS Topology Suite, JAI Replacement, TilelessMap, PostGIS, 
SHOGun, react-geo, Saga, OSGeoLive, owslib, debian/ubuntu, UbuntuGIS, 
OpenLayers, MapServer, QGIS, GeoExt 3, Nominatim, GDAL, t-rex, PyWPS, 
GRASS GIS, OWSLib, pygeometa, MapServer, geocatalogo, GeoNode, OTB,

snappy, OSM-Vector-Tiles, Geonetwork, Geoserver, OpenLayers Editor, 
Noise, CouchDB, MS4W, EOxServer,  maposmatic, mapnik, Mapbender, gvSIG, 
gvSIG Mobile, Geopaparazzi, pyModis, GeoMajas, GeoHealthCheck, Stetl, 
Entwine, Greyhound, deegree, TEAM Engine, actinia, 3DCityDB and testing

track the API change

Raster Processing Engine

* Spent a lot of time reverse engineering the raster processing 
requireemnts of the Java community, starting with the GeoTools project 
and branching out to the JAI-Ext and JAI Tools code-base as required.
* An initial architecture spike 
(https://github.com/locationtech/rasterprocessingengine) was created, 
providing an easy to use "builder" API, backed by the JAI-Ext 
implementation of affine transformation

The event also played host to some community building activities:  
FOSS4G 2019 organization, OSGeo board meeting, OSGeo marketing 
committee, MoU between TIB and OSGeo, OSGeo member meeting.

OSGeo Member meeting
------------------------
The OSGeo Member Meeting took place in Bonn at BaseCamp at March 19th 
2018 during the OSGeo Code Sprint. About 50 people came to the Member 
Meeting and from the board María Arias de Reyna, Jody Garnett, Vasile 
Craciunescu, Michael Smith, Angelos Tzotsos and Astrid Emde were

When not working, attendees did enjoy exploring the town, making for 
some great "geobeer" discussion. The sprint was held in conjunction with 
the FOSSGIS Conference (https://fossgis-konferenz.de/2018/), the 
regional "foss4g" event for Germany. The crew enjoyed a little bit of 
socializing, with code sprinters joining the "gala event" and 
contributing to the festive atmosphere and dancing. The city itself 
provided many distractions, with computational device museum being a 
highlight.

We would like to thank Bonn for showing everyone such hospitality, and 
looking forward to the next OSGeo Code Sprint!
