    • And More Rendering● Point label displacement● DPI scaling● Faster Recode/Categorize● Performance improvements on multilayer maps
    • Raster
    • Faster Raster ReprojectionPiecewise linearapproximation
    • Faster Raster Reprojection
    • Non Georeferenced Rasters EPSG:404000
    • Image Mosaic Improvements● Attach attributes to tiles● Filter by attribute● Filter by time/elevation● Autoindexing of directories● External indexes ○ any GT datastore ○ third party indexes● Multithreaded loading of granules● Footprint support
    • Automatic Image PyramidsAutomatically: ● recognize gdal_retile structure ● building mosaic index
    • ImageIO-Ext Improvements● BigTiff support ○ Read/Write ○ Overviews● Improved GeoTiff ○ external overviews ○ new plugin underway● Improved JPEG2000 support ○ kakadu based ○ additional code params ○ fine grain control on writing● Improved Tiff metadata management ○ wiser caching ○ less memory - more speed
    • Direct Raster Rendering Path● Hit JAVA2D Bottleneck – Scalability Issue ○ http://bit.ly/qJcZBi ○ http://bit.ly/oe0CHo● Created direct raster rendering path with JAI ○ Drop-in replacement (1 raster at time) ○ 2x speedup ○ 2x/3x scalability improvement under heavy load ○ Enabled/Disabled via Java Switch
    • And More Raster● Oracle GeoRaster● JPEG 2K improvements● More Concurrency● Simplified/Shrunk Raster Operation Chains
    • Web UI
    • Web UI CRS Area of Validity DisplayEPSG:32612, UTM 12N EPSG:32614, UTM 14N
    • Web UI Legend previewLog viewer
    • Web UI Graphical file chooser
    • Application Schema Support● Recent development by CSIRO● Full extension status● Feature chaining, polymorphism● Better performance, memory use● GML 3.2, WMS (beta)
    • Projections Robinson Mollweide Winkel Tripel Eckert IVEquidistant conic
    • Web Map Service (WMS)

    • SQL ViewsLayers from SQL request=GetMap &layers=continents &viewparams=region:2
    • Virtual ServicesService and catalog views per workspace
    • Control Flow● OWS request throttling based on: ○ Number of concurrent requests total ○ Number of concurrent requests per: ■ service ■ operation ■ output format ■ user● Requests queued when limits reached
    • Control Flow
    • Control Flow
    • Cross Layer Filtering<wfs:Query typeName="sf:bugsites"> <ogc:Filter> <ogc:Intersects> <ogc:PropertyName>the_geom</ogc:PropertyName> <ogc:Function name="querySingle"> <ogc:Literal>sf:restricted</ogc:Literal> <ogc:Literal>the_geom</ogc:Literal> <ogc:Literal>cat = 3</ogc:Literal> </ogc:Function> </ogc:Intersects> </ogc:Filter></wfs:Query>
