  3. Imagery and Raster Management Issues • Multiple Sources • Multiple times • Multiple Formats • Increasing Bit Depths, resolution and Bands • Metadata standards vary • Storage Requirements • Access and Performance Managing Imagery and Raster Data Using Mosaic Datasets

  4. What is a Mosaic Dataset? • Catalog of • Imagery • Associated metadata • Processing functions to be applied • Stored in Geodatabase • Authored using ArcGIS for Desktop • Enables • Dynamic Mosaicking • On-the-fly processing Managing Imagery and Raster Data Using Mosaic Datasets

  5. Creating a Mosaic Dataset Demonstration Managing Imagery and Raster Data Using Mosaic Datasets

  6. Mosaic imagery from multiple tiles User can query mosaic Year = 2014 Dynamic Mosaicking Mosaicking Multiple Images On Demand 2015 2014 2013

  7. Processes Extract Bands Hillshade, Shaded Relief Stretch Applied to Individual rasters Compete Mosaic On-The-Fly Processing Creating Multiple Products from a Single Source

  8. Working with Mosaic Datasets Demonstration

  9. 2 Ways to Serve Imagery Directly from individual raster dataset From mosaic dataset (requires image extension) Sharing Imagery Publish to Server Image.tif Image1.tif Publish to Server Image2.tif Image Extension Mosaic Dataset Image3.tif

  10. On-The-Fly Processing Image processing algorithms OTF Process Imagery as Accessed Multiple information products Directly from single source May be chained together 40+ image processing functions Stretch, filters, orthorectification, NDVI, pan sharpening, hillshade, slope, etc. Image Services Empowering technology - On-the-fly Processing - Raster Functions fx fx fx fx Image service Source images Mosaic dataset Image services Empowering technology on-the-fly processing
