    • Whats new inGeoServer 2.2 Andrea Aime GeoSolutions Justin Deoliveira Opengeo
    • Web Map Service (WMS)
    • Time and Elevation
    • Time/elevation for vectors● Single time (instant) support● Interval validity support by selecting two attributes● "Current" time always up to date● Currently investigating integration with measured geometries and dimension based slicing
    • Time/elevation for rasters● Image mosaic with time/elevation attributes in the tile index● Tile index in shapefile or database● Automatic extraction of time/elevation from file names via regular expressions
    • Time and Elevation...&request=GetMap &time=2001-08-01T18:00:00Z/2001-09-01T00:00:00Z ...&request=GetMap &time=2003-08-01T18:00:00Z/2003-10-01T00:00:00Z
    • Animated Time and Elevation...&request=GetMap&time=2001-08-02T10:00:00.000Z,2001-08-02T16:00:00.000Z,2001-08-02T22:00:00.000Z,2001-08-03T04:00:00.000Z,2001-08-03T10:00:00.000Z,2001-08-03T22:00:00.000Z,2001-08-04T04:00:00.000Z,2001-08-04T10:00:00.000Z,.......2001-08-07T16:00:00.000Z,2001-08-07T22:00:00.000Z,2001-08-08T04:00:00.000Z,2001-08-14T16:00:00.000Z,2001-08-14T22:00:00.000Z,2001-08-15T04:00:00.000Z,2001-08-15T10:00:00.000Z,2001-08-15T16:00:00.000Z,2001-08-15T22:00:00.000Z&format_options=gif_frames_delay:200;gif_loop_continuosly:true&format=image/gif;subtype=animated But... why limit animations to just to time and elevation?
    • Rendering transformations
    • Rendering transformations Contour lines
    • Rendering transformations Extract points, show elevation
    • Rendering transformations Heat maps
    • Rendering transformations Surface interpolation
    • Rendering transformations Point clustering
    • Web Feature Service (WFS)
    • WFS 2.0 Paging...&request=GetFeature&startIndex=5&count=6&...
    • WFS 2.0 Stored Queries<wfs:CreateStoredQuery> <wfs:StoredQueryDefinition id=bbox> <wfs:Parameter name=AreaOfInterest type=gml:Polygon/> <wfs:QueryExpressionText returnFeatureTypes=topp:states> <wfs:Query typeNames=topp:states> <fes:Filter> <fes:BBOX> <fes:ValueReference>the_geom</fes:ValueReference> <gml:Envelope> <gml:lowerCorner>${x1} ${y1}</gml:lowerCorner> <gml:upperCorner>${x2} ${y2}</gml:upperCorner> </gml:Envelope> </fes:BBOX> </fes:Within> </fes:Filter> </wfs:Query> </wfs:QueryExpressionText> </wfs:StoredQueryDefinition></wfs:CreateStoredQuery> ...&request=GetFeature&storedQueryId=bbox &x1=-180&y1=-90&x2=180&y2=90
    • WFS 2.0 Extended Operators<fes:Filter><fes:PropertyIsEqualTo> <fes:Function name="strMatches"> <fes:ValueReference>name</fes:ValueReference> <fes:Literal>name-f002</fes:Literal> </fes:Function> <fes:Literal>true</fes:Literal></PropertyIsEqualTo></fes:Filter> <fes:Filter> <foo:strMatches> <fes:ValueReference>name</fes:ValueReference> <fes:Literal>name-f002</fes:Literal> </foo:strMatches> </fes:Filter>
    • Web Processing Service (WPS)
    • Asynchronous calls
    • Security
    • Authentication
    • Authentication LDAP
    • User Groups
    • Passwords
    • Referencing
    • NTv2 and NADCon support● Support for high accuracy datum changes based on datum shift grids● Error down from 4m (if youre lucky) to few centimeters ○ NTV2: canadian grid shift standard, used in Europe and Australia too ○ NADCon: american grid shift standard● Support for official EPSG grid files● Ability to add your own custom ones (work in progress)
    • Reprojection console● Reproject single point or geometries● Check what exact transformation is being used
    • Un-referenced data● Serve unreferenced data: ○ CAD data (floor plans and the like) ○ large photos● Made up new code to handle such data: EPSG:404000
    • Data access
    • Database level security
    • WFS sorting and paging● Available in all WFS versions (in 1.0 and 1.1 as a vendor param, startIndex/maxFeatures)● Native, most efficient in spatial databases● Emulated in all other data sources (suitable for smaller data sets)
    • New experimental OGR store● OGR: rich set of readable formats● Does not need special bridge libraries (uses BridJ to connect to native lib)● Slower performance than native Java formats, suitable for smaller data sets
    • Image collection store● Publish collection of non georeferenced images via WMS (eventually time varying)● List and search provided off band as a separate tool● One layer, select image with CQL_FILTER
