Image Mosaic Improvements

• Attach attributes to tiles• Filter by attribute• Filter by time/elevation• Autoindexing of directories• External indexes 

o any GT datastoreo third party indexes

• Multithreaded loading of granules• Footprint support

Automatic Image Pyramids

Automatically:• recognize gdal_retile structure• building mosaic index

ImageIO-Ext Improvements

• BigTiff supporto  Read/Writeo  Overviews

• Improved GeoTiffo external overviewso new plugin underway

• Improved JPEG2000 supporto kakadu basedo additional code paramso fine grain control on writing

• Improved Tiff metadata managemento wiser cachingo less memory - more speed

Direct Raster Rendering Path

• Hit JAVA2D Bottleneck – Scalability Issueo http://bit.ly/qJcZBio http://bit.ly/oe0CHo

• Created direct raster rendering path with JAIo Drop-in replacement (1 raster at 

time)o 2x speedupo 2x/3x scalability improvement under
