• Using JMeter to generate load against a local GeoServer Using a XP Pro box, 3GB memory, 3Ghz dual core processor
• Rising number of concurrent requests, reports average response time (lower bars are better)

• WMS requests against a 6000x4800 GeoTiff, extracting 256x256 tiles at various resolutions
• Per layer security• WFS reprojection• GDAL raster drivers, raster symbolizer• GeoWebCache, KML SuperOverlays• ...
New features in detail
Per layer security• Ability to specify access rule on a layer by layer
basis• Simple configuration based on a list of rules
following this template:namespace.layer.mode=role1,role2,...
A name, or * tomean “any”
r: readw: write
The roles that willbe authorized to access the dataunder this rule
Per layer security, example
*.*.r=**.*.w=NO_ONEprivate.*.r=TRUSTED_ROLEprivate.*.w=TRUSTED_ROLEtopp.districts.w=LEGISLATORS
private.* topp.*
TRUSTED_ROLE r/w r r r(no access) r r/w r(no access) r r r
topp.districts
Other layers
LEGISLATORS (all other users)
Basic read only lock down
Per layer overrides
GDAL integration• By means of the ImageIO-ext library,
GeoServer can now support MrSID, JPEG 2000, ECW and a subset of other GDAL supported formats
• Requires platform dependent binary extensions, available only for Windows and Linux at the moment (contributions welcomed!)
• Very good performance, see the benchmark related presentation
• ECW reader not included in the standard download due to licensing issues
geo-solutions.it
Raster symbolizer support• Significantly improved, now supports:
– color ramp– band selection– contrast enhancement– opacity and gamma correction

GeoWebCache integration
GeoServer
GeoWebCache
Persistent raster/KMLtile cache
• Caches tiles as used by most common slippy map interfaces
• Ideal for layers that rarely change
• Delivers raster/KML tiles to:– OpenLayers– Google Maps and Google
Earth– Microsoft Virtual Earth
• Speeds up data delivery by a factor or 10-100
KML SuperOverlays• Problem: you have a huge data set you want to
display on Google Earth– the generated KML is simply too big– the features you want to display have a clear
hierarchy– zoomed out, you want to display only the most
important ones, – less important should appear progressively, as
you zoom in, while leaving the important ones visible
– of course, everything should happen in the most fluid way
KML SuperOverlays •Solution–create a pyramid like structure–have Google Earth regions drive what is visible at each scale–use a tile cache to maximize delivery speed•This requires GeoServer 1.7.0 and the GeoWebCache plug-in
KML superoverlays
A sample from the global biodiversity database (www.gbif.org), distribution of the Cape Hope Squid (Loligo Vulgaris Reynaudi)
Improved preview• Play with tiling, antialiasing, format and map
size• Issue dynamic filters on your data
Other improvements• Significant ArcSDE improvements
– Less connections used during normal operation– Supports versioning, read and write against the
default version– Uses native ArcSDE transactions on write
• Support for Xlink in WFS 1.1
• Fully new WCS 1.1 module (GeoServer being the reference implementation of it)
• New user interface• REST configuration API• Brand new Oracle data store• N-dimensional rasters• WPS 1.0• and more...
What's cooking?
New user interface• Developed in collaboration with interface and
interaction designers• Fully AJAX based• Most functionality within a few clicks from the
root of the administration interface• Service extensions can now plug in their extra
configuration UI• Based on the open source Wicket framework
(wicket.apache.org)
REST configuration• Prototype worked on during the last year• Allows full programmatic configuration using
simple REST calls (e.g., mass configuring 100 layers, adding new data as it comes in, etc.).
• Will be further developed in the 2.0.x series
New Oracle data store• Current Oracle data store giving you
headaches? Try the new one:– Full rewrite– Deeper testing– No more date/time/timestamp issues– Better security– Better performance– Support for some 3D geometry structures
• The base for a new series of database backed data stores (yes, PostGIS, I'm looking at you!)
Forget flat rasters...• Support for N-dimensional coverages (3d + time)• Full WCS support, mapping slices using WMS
time and elevation parameters • Being coded right now in a branch
geo-solutions.it
Web Processing Service 1.0• A new WPS 1.0 plug-in is sitting in the
GeoServer community area• Finally some spatial analysis!• At the moment, only sample processes
– simple addition– geometry union, intersection
• But with an API that allows you to build new ones, so jump in!
And more!• Google searchable datasets:
– Following the KML super-overlays work, make the datasets searchable by Google
– Very interesting if you need to disseminate big amounts of data in a way that allows most people to find them and import them in Google Earth
• Complex features– CSIRO (http://www.csiro.au/) is poking GeoServer in
an attempt to add complex features– Next year might come with big suprises
WFS: full reprojection support• Have your client work in a completely different
projection than the data native one:– Reproject WFS output to another spatial
reference system – Insert data in SRS other than the native one– Express filters in an SRS other than the native
one• E.g., make a OpenLayers web based editing
client and use Google tiles (in spheric mercator projection) as a backdrop
• Works even with WFS 1.0 (as a custom extension)
