2nd Marble Developer Weekend Sprint, October 19-21 2012

We'd like to invite all people who are interested in Marble Development: may it be through coding, graphics design, promotion, packaging, documentation, website or other areas.

The Marble Developer Weekend Sprint will be held at the OpenSUSE Conference 2012 in Prague.

You have an interesting story to tell about Marble? You'd like to make Marble a great educational tool? You've built some software based on Marble? You're a Marble newbie and you'd like to get involved with KDE-EDU or Marble development? You dream of Navigation and Routing with Marble? -- We'd like to see you at the sprint!

The Marble Weekend Sprint is sponsored by the KDE e.V.. Thanks a lot for supporting Marble!

Dates

The Marble Sprint will be held from October 19-21, with the following basic schedule:

19.10. arrival, starting from 16:00 local time (Friday). I suggest we meet at the Cafe Traverza. That will be the same place where the openSUSE conference welcome party takes place. See:

http://en.opensuse.org/openSUSE:Conference_party_announcement

Jens-Michael and me will arrive at about 21:00 at this place. We could then meet there. Once everybody has arrived we could decide whether we stay in this place or whether we move to a different place in order to have dinner.

20.10. sprint (Saturday), Lightning talks after noon.
21.10. sprint (Sunday) and departure starting from 18:00 local time.
22.10.-23.10. Marble Hacking Marathon

Location & Accomodation

The 2nd Marble Developer Weekend will be held at the OpenSUSE Conference 2012 in Prague. We will get a special dedicated room for our Marble sprint.

For Accomodation the same suggestions apply as for the OpenSUSE conference: See the webpage Accomodation on the openSuSE Conference website for more details.

Hotel Krystal is one of the primary addresses there and costs about 40 EUR for two persons per night.

How to get there

T: task I: information S: suggestion

Outreach

I: __Server__ needed for satellite tiles, routing data, osm vector data
- I: Format/data need of osm vector data yet unknown
- I: current routing data is about 30 GB, RAM > 2 GB would be ideal for conversion
I: No existing KDE server available, __funding__ needed
- T: Approach KDE e.v. and ask for funding to get started
- T: Ask community for funding (permanent possibility, e.g. donations via the website, optional payed (donate) versions of mobile apps)
- T: Determine organizational needs of funding (own account? sub-account of KDE e.v. possible?)
- I: OsGEO might be an alternative as well
PR/Marketing: How to make users and developers aware of Marble?
- I: Communications with people on fairs suggests that Marble is still quite unknown
- I: Articles (e.g. ct, ix), more presence on fairs would help
- (done) ~~T: Redo the edu.kde.org/marble front page, update wikis (wikipedia openstreetmap)~~
  - ~~S: Place content on marble-globe.org and keep only kde edu specific parts on kde-edu.org/marble~~
- T: Bug 310059 Open .kmz files
- (done) ~~T: Open .gpx files~~
- T: Bug 310058 Different user-agent strings for mobile versions
- T: Generate a list of papercuts (and fix them)

Fairs/Events

Technical

Use Case: Partial Map Import/Export
- e.g. storing the visible region of the map shape in an odf file and opening it on a different system without Internet access
- S: Possible implementation: Tile pyramid, .kml creation, merge into .kmz file. Remark: Not easy to implement
- S: Possible alternative: Tile pyramid, store tiles with odf file, insert tiles into local cache on opening .odf again
Notification of all data being loaded/available
- e.g. to create a snapshot, print a map
- S: as a workaround (hack) one could monitor the download queue to become empty (this approach has obvious problems)
Data
- GPS Data Model
  - T: Proper representation of tracks with timestamps (done already), speed, accuracy in KML
  - T: (Bug 303071) Export of tracks to .gpx (keeping all useful information from GPS devices)
- API for Vector Model
- Shapefiles (shp)
- Access to GeoData Model
- KMZ
- Importing Data
Tiles
- Threaded TileLoading
- Blending Extension
- Embedding Tiles into Document
Layers
