Faster Raster Reprojection

Piecewise linear approximation

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 Pyramids

Automatically:● 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

● Oracle GeoRaster● JPEG 2K improvements● More Concurrency● Simplified/Shrunk Raster Operation
