Using Imagery in ArcGIS

  1. 1. TW: Using Imagery in ArcGIS 27th of October 2011 - 16.30 to 18.00held by: Guenter Doerffel Technical Marketing Lead SynerGIS Austria (Distributor Austria) g.doerffel@mysynergis.com
  2. 2. The Description in the Agenda
  3. 3. A rough plan for this afternoon • Images as attributes and attachements • Single Image Files in ArcGIS for Desktop • Images/Raster and the Geodatabase - Raster Dataset - Raster Catalog - Mosaic Dataset • Serving Imagery: Image Services Always included: Whats comming with ArcGIS 10.1
  4. 4. Raster/Imagery as attribute • Create with ArcGIS for Desktop Standard+ • Any picture will do • No need for a Spatial Reference • Only one raster column per Table - Use relationship if you need more than 1:1 • What can you do? Raster in Feld Klick geladen See it!
  5. 5. Raster/Imagery as attachement (new in 10!) • Anything will do • No need for a Spatial Reference • Relationship class to a feature class • Objects stored in Geodatabase • Opened with „System application“ • Usable in WebMapping Apps
  6. 6. DEMO No. 1Add a raster attribute to a table Use it where you see itAdd attachements to a feature class Use it where you see it
  7. 7. Using (single) File-based raster (datasets) • Access in ArcGIS 10 is unified by GDAL-libraries (Geospatial Data Abstraction Library – gdal.org) • Format Support for read/write differs: - Read: Lossless and lossy - Write: predominantly lossless formats • „A Raster“ = the Image PLUS other files: - *.ovr (Overviews/Pyramids) … used to be *.rrd - *.prj/prjx*.??w … Projection/WorldFile - *.aux.xml … Statistics, Spatial Reference, Metadata • Many settings in ArcMap/Advanced Settings
  8. 8. Direct Access using ArcGIS and File based raster • Many Improvements with Default-Formats - Compression - Standards - TIF (vs IMG) - .OVR (vs .RRD) - Stats (.aux.xml) • Imporved GPTools - Recursive Pyramids - Statistics Optimized Access for existing and new/future formats
  9. 9. Settings for Images • ArcMap Settings for Raster - In ArcMap Settings - In GP Environment • Advanced ArcMap Settings - More here
  10. 10. 10.1: ArcMap Options - RasterExtended Defaults • More Raster Properties used • Adjust to meet your preferences
  11. 11. Optimized Raster display • Optimize Display-Performance • Uses Caching/Threading • For all Types of Imagery - Local Raster - “Mosaic Dataset” - Image Services • Dynamic Properties remain • Use as “Operational Layer” • Hardware-Accelleration supported
  12. 12. The “Image Analysis” Window … • Settings at your fingertips - Contrast, Brightness, Gamma, Stretching - Dynamic Range Adjustment - Transparency • Simple Interpretation - Zoom 1:1, Top Up - Difference - Sampling • On-The-Fly Processes - Orthorektifikation, pan-sharpening - Clip, Mosaicking - NDVI, Shaded Relief “One-Click” Access for frequently used functions
  13. 13. … in 10.1 becomes a Image Analysis Window +3 mayor enhancements • Interaktive Stretch (1) • Raster Function Button (2) • Mensuration (3) 12.4m
  14. 14. DEMO No. 2Raster Settings you should be aware ofOptimized Display (vs. Basemap-Layer)Image Analysis Window (10.1)
  15. 15. A raster type is more than a raster dataset … • Introducing the „raster type“ - Supported (only) by Mosaic Datasets - identifies metadata (georeferencing, acquisition date, sensor type) along with a raster format - Files, tables, WebServices products (like satellite sensor) - Online Help
  16. 16. … and with 10.1 becomes the „Raster product“Available to everybody everywhere in ArcGIS • Very easy to handle • „Image Intelligence“ massively improved! 10 10.1
  17. 17. A LITTLE 10.1 DEMOLoad a Raster product into ArcGIS for Desktop
  18. 18. Images as Geodatabase-Datasets • Raster-Dataset - One Entity – managed in the Geodatabase - Often the result of a mosaicking process - Same content in different resolutions (pyramids) • Raster-Catalog - Group of Raster-Datasets - Client regards them One Entity - Every part in fact is a Raster-Dataset - Every part can be different - Managed/Unmanaged - Can be time-aware
  19. 19. Raster-Dataset • For a long time THE element to store rasters in a GDB • Major properties: - Pyramids, Spatial reference, Statistics • Fast display at all scales • Stored with a tiling schema Image Image - Required – not apparent to the enduser - Tilesize defined when loading - Pyramids then tiled, too • Always somehow converts/resamples! Mosaic • Mosaic - Initial tiles are „glued“ together – overlap gets lost • Metadata only on the dataset level
  20. 20. Raster pyramids always show the same content .. 10 m Level 0 20m Level 1 40 m Level 2 Different cell sizes 80m Level 3A
  21. 21. Raster-Catalog • Grouped Raster-Datasets • Storage of Footprint-Polygons with their Raster-Datasets • Managed or Unmanaged - Unmanaged - Only a file location reference gets stored - Supported in Personal- and File-GDB - Advantage: base-Data unchanged - Managed - Pixel converted into Geodatabase - Supported in all GDB-Types - Base-Data gets changed • Usable for Animations/Time-Series
  22. 22. …by the way – still exists • Raster-Catalog based on a simple table - Any Table (in or out of Geodatabase) • Must-structure: IMAGE, XMIN, YMIN, XMAX, YMAX - IMAGE - full Path / relative Path / UNC Path or environment-variable to the source of the data • Display-Order is table record order
  23. 23. „Best of breed“: The Mosaic Dataset • Combines advantages of Unmanaged Catalog and Raster Datset • Can combine data of different resolution, color model, spatial reference, meaning … in different scales • Knows about raster types/products • Knows about (on the fly) raster functions • Can dynamically mosaic using different methods • Allows access to table for selection, download, upload (10.1) • Can create Referenced Mosaics (derived results) • Is time-aware
  24. 24. Organizing rasters as a mosaic dataset Image 1 Image 2 Image 3 Image 4 Source images Mosaic datasetA
  25. 25. Overviews are not (always) pyramids …. 10 m Level 0 20m Level 1 40 m Level 2 Different cell sizes 80m Level 3A
  26. 26. The structure of a MosaicDataset • Group-Layer display in ArcMap: - Boundary Whatever you want the extent of the Service to be - Footprint The extent of participating images Can be changed! - (Seamline) Where mosaicking is to take place - Image The Image delivered – with many additional settings
  27. 27. Mosaic methods control display order Closest to Center Area of InterestA
  28. 28. Mosaic methods control display order Closest to Nadir NadirA
  29. 29. Mosaic methods control display order By Attribute With no Cloud cover With Cloud cover By Cloud cover By Acquisition DateA D
  30. 30. DEMO No. 4Mosaic Dataset PropertiesDifferent mosaic methodsDynamic compressionRaster functionsReferenced Mosaic
  31. 31. Serving single raster datasets • Can be done without Image Extension • Allows IMAGING, WCS, WMS • Set Size, Resampling, compression on server
  32. 32. Serving mosaic datasets • Many more server-sided settings: - Size - Number of rasters - Resampling - Compression - MosaicMethods - Table/catalog access - Metadata level - Fields - Download - Upload (10.1) - Mensuration (10.1)
  33. 33. DEMO No. 5Raster Dataset Properties on the serverMosaic Dataset Properties on the server Client effects A sample web client
  34. 34. Caching Image Services • Why? - Reduce server load - No need for on-the-fly processes - Provide max. compatibility with other cached services - The „Web-feeling“ needs to be there • How? - 10: Always via an mxd-based service - 10.1: Default of ImageService can be cached
  35. 35. Me gustaría dar las gracias aI would like to thank• Tracasa• Aurensis• la Junta de Andalucía• el Instituto Geográfico Nacional• y a Esri Españapor su colaboración en los datos usados en este workshop for their collaboration with the data used for this presentation
