  2. LiDAR Compressor • Compress point cloud data to MrSID Generation 4 (MG4) • Lossless • 25% of the original size • Some datasets can be compressed to 15% or smaller of their original size • Lossy • Performs lossless compression first • Points are decimated to achieve target file size

  3. LiDAR Compressor benefits • Rapid viewing • Easily manage your entire point cloud • MrSID Generation 4 LiDAR files are supported in: • ESRI ArcGIS 3D Analyst • Merrick MARS® 6.0 • Global Mapper 11.0 • LizardTech GeoViewer • More to come soon! • Easy to use • Minimal training required

  4. LiDAR Compressor

  5. GeoExpress 7 • Compression without compromise • Visually lossless at 5% of the original file size • Digitally lossless at 50% of the original file size 100 MB GeoTIFF 5 MB MrSID

  6. GeoExpress 7 Your choice of output image format: JPEG 2000 MrSID • ISO standard • Unlimited file sizes • Lossless compression • Multispectral images • Profiles • Industry standard • Unlimited file sizes • Lossless compression • Optimization

  7. GeoExpress 7 Images load and display faster 100 MB GeoTIFF (3 seconds) 5 MB MrSID (< 1 second)

  8. GeoExpress 7 • Supportedin almost every major GIS application • ESRI • ERDAS • Bentley • Autodesk • Intergraph • MapInfo • Google Earth and many, many others …

  9. Lat/Long UTM Zone 10N GeoExpress 7 GeoExpress 7 • Image Reprojection • Reproject imagery to over 2000 pre-defined systems • Easily define, save, and share custom coordinate systems for later use • Mosaic images from multiple coordinate systems

  10. GeoExpress 7 GeoExpress 7 Color Balancing • Automatically or manually balance images • Automatically correct vignette and tilt • Automatically smooth seam lines

  11. GeoExpress 7 • “Despeckling” tools in GeoExpress 7 • Compress “collar” areas of imagery losslessly • Retain color values • No speckling • Apply to old datasets to clean up edges

  12. Before despeckling…

  13. …and after despeckling

  14. Express Server • Rapidly deliver large datasets of raster imagery to any device – ever over low bandwidth connections • Satisfy more image requests faster • Increase the speed of delivery without any additional investment in hardware or bandwidth • Easy to set up and easy to administer

  15. Express Server • Works with existing image servers • View your maps up to 25 times faster than with ArcGIS Server or ArcGIS Image Server alone • Serves imagery to most GIS applications • Work with remote datasets hundreds of gigabytes in size right on your desktop • WMS Support delivers imagery to any WMS client
