In fact, I’ve performance problems loading data in OpenLayers format (WMS) in GeoServer and don’t know what caching mechanism to apply if somoe one can suggest an easier approach to apply in out of the box GeoServer implementation.

Thanks !

I’ve been looking for that for a while without much luck. If it’s just for background mapping then the best option might be to use the mapserver symbologies that can be found on the edonica site listed above, and then use that as a wms feed in your desktop GIS. I guess WFS as well, if you’re feeling patient. If I think of another approach (this being something I’m working with quite a lot at the moment) I will post an update.

Cheers

Don’t suppose you have any ideas on how to sort out the symbology for the resulting shapefiles? Preferably in QGIS, but equally anywhere I could find symbology files for ArcGIS as well?

MMimport is awesome, and thanks for pointing it out!

Stu

Funny, I should known what’s in the GDAL FAQ but seems I didn’t
Anyway, we have answer related to your question in there:
How can I merge hundreds of shapefiles?

Thanks for the suggestions- they are fab! (I sense a little batch file coming up…)

Jo

Yes, I think you are right.

Yes – agreed, though I suspect the bottleneck in this case will be reading in the data, building spatial indexes rather than in the pausing and spawning of new processes.

…or xargs command:

find . -name ABC | xargs ogr2ogr …

xargs is usually faster than -exec, what may be important while working with huge sets of files.

If you want to do anything with some group of files then find’s exec option is (usually) your friend.

eg to find all the files named ‘MM_TopographicArea_*’ in the current directory (and its subdirectories) and append it to foo.shp you’d do something like:

find . -name MM_TopographicArea_* -exec ogr2ogr -update -append foo.shp {} -nln foo \;

the command in the -exec option is executed for each file matching the -name parameter. The -exec option replaces any instances of {} with the matched filename and is terminated by \;

Hope that helps,

Andrew
