Agenda

  • What more is needed to get OSGeo's Geodata Repository running at Telascience
    • User accounts to ask SAC for if needed
    • Responsibilities for different data sets
  • What kind of portal is needed - is wiki enough?
  • Some type of browsing interface for the data neccesary:
    • OpenLayers for Raster/Vector data? Easy to set up, might not be full featured enough for some people?
    • Perhaps Ka-Map's tile.php as cached layer to feed both kamap and openlayers?
    • Single-image screenshots for Raster data as overviews
    • Vector dataset descriptions: What various attributes are/mean (better metadata)
    • GeoRSS out to get updates, with bounding boxes -- need to get some way to display this data, does anything do GeoRSS rendering with bounding boxes right now?
  • Free Earth Foundation working on distributed open geodata services targeted at WorldWind - how can we help?
  • Feedback appreciated on metadata client
  • Please feel free to add items here

Minutes

In the meeting, we discussed: 

* Current Status of Telescience hosting. The infrastructure is
 set up, and users who are looking to contribute to the effort should
 be able to get accounts -- talk to the System Administration
 Committee for access.
* What kind of Data display framework is necesary for the geodata
 repository to start with? Wiki was discussed: In the backend,
 structured metadata will be stored, but the wiki-nature will allow
 for descriptive (non-normative) content to be added, which may later
 migrate to metadata storage when a more permanent solution arises.
* Data storage should have three 'levels' of data:
  * Raw files. (Shapefiles, images, etc.) These would be designed for
    use in cases where the default styling is 'not good enough' for
    users who are attempting to use the data, or cases where data
    processing is required, or whatever.
  * WMS Server: For cases when you need to have the full WMS support,
    there should be WMS servers available for datasets where it is
    applicable. (WFS, and other similar OGC web services, would also
    fit here.)
  * Tiled Server: Datasets where tiling is applicable would have
    support for making fast, cached requests against tiled-on-disk
    datasets. nhv and others express an interest in getting a standard
    for tile caching set up before we do too much work on this aspect
    of it.

On the agenda, but not covered, were some visual suggestions for how data should be exposed from the geodata repository browsing interface: 

  * OpenLayers for Raster/Vector data? Easy to set up, might not be
    full featured enough for some people?
  * Perhaps Ka-Map's tile.php as cached layer to feed both kamap and
    openlayers?
  * Single-image screenshots for Raster data as overviews
  * Vector dataset descriptions: What various attributes are/mean
    (better metadata)
  * GeoRSS out to get updates, with bounding boxes -- need to get some
    way to display this data, does anything do GeoRSS rendering with
    bounding boxes right now?

This was tabled until the next meeting.

Jo offered 

https://geodata.osgeo.org/source/browse/geodata/trunk/metadata/

as her work on a MetaData client, to collect data from shapefiles, etc. and put it into a database.

At approximately this time, we reviewed the content of the meeting, and adjourned for two weeks, same bat time, same bat channel.
