Compression Recommendations(continued)• Serve ArcSDE raster data via ArcIMS– To avoid too much loss (prototype your solution)– If you store lossy, , serve image with loss-lesslesscompression• i.e. PNG– If you store loss-less, less, serve either lossy or loss-lessless• When loading lossy-compressed files such asJPEG, MrSID, , ECW, JPEG2000– Load and view sample, then verify visual quality– May require use of loss-less less compression in ArcSDE• Lossy compression may affect scale of use– Due to degradation of raster quality
