dear all,

A *lot* of dots that join up nicely in this...

Jo,


Dave Sampson here... I'm just going to pump out some info here and maybe 
you can direct it to the right people.

I run the Ottawa GRASS Users Group (OGUG) 
[http://cemml.carleton.ca:8080/OGUG/] and we have a bunch of mini local 
projects that would work nicely with some of the working groups....  
Pass this info along and see what people want to do with what.

Lets go on a tour.

Canadian verison of the PGL Liscence that we are trying to promote...

Some of our listings for free geographic data
http://cemml.carleton.ca:8080/OGUG/test/public-data-sources/

Sources for GRASS Data
http://cemml.carleton.ca:8080/OGUG/test/grass-data

Sources for papers on GRASS
http://cemml.carleton.ca:8080/OGUG/ogug-community/grass-papers/

Some home brew tutorials and student workshops
http://cemml.carleton.ca:8080/OGUG/ogug-community/tutorials/

OGUG datasets
http://cemml.carleton.ca:8080/OGUG/test/ogug-data

We are trying to create local training datasets using free geo data from 
disparate sources... same idea as the GRASS spearfish data but something 
with a Canadian context.

here we want to develop a method of community mapping interchange 
files... I am thinking in grosse concept something like an SVN using 
non-binary GML  but this is outside my expertise. I'm only a geographer 
not a DBAdmin of Concurrent versioning pro.... I also know little about 
GML... but the process seems to work well with sources code, so why not 
non-binary GML's.

There are many things that OGUG can do with some additional networking 
and support. Perhaps some of our projects can co-operate... you at least 
have a keen group interested in working with OS GEO foundation to get 
the ball rolling. Let us know how we can help and perhaps some joint 
funded projects might come out of the woodworks.

For your metadata projects. As much as I hate the whole subject I spent 
4 months managing a project to implement metadata search capabilities 
into a government web site.  Check out the final porduct here:
http://geoportail-geoportal.ainc-inac.gc.ca/metaindex_e.asp

This page uses IFrames ot exploit the tools found at this canadian 
geospatial website:
http://geodiscover.cgdi.ca/gdp/index.jsp?language=en

There is a whole API available for people to search their DB.  Also 
theey can also search a z.39.50 type database and working to work with 
http metadta servers. heck out their developer section. No sense 
re-inventing the wheel....  its a pretty widely used site for North 
American data.
http://geodiscover.cgdi.ca/gdp/help?request=WebAPIGuide

The only thing I would like to see with this services is a caching 
ability to quickly retrieve search results.

Anyhow.. some thoughts for your groups.

Cheers
