1. September 2010, Gaeta, Italy X th International Scientific and Technical Conference From Imagery to Map: Digital Photogrammetric Technologies Alexandra Kiseleva Manager of Technical Support Department Effective techniques for working in PHOTOMOD

2.  Resource system. Creating data structure  Resource system. Network profiles management  ADS imagery processing. Data preparation  Import of orientation data for digital frame cameras  UltraCam data processing. Metadata import  Creating block layout for automatic tie points measurement  Block layout accuracy control  Improving block layout with DEM  Show marker position in Google Maps and Yandex Maps  Distributed processing

3. PHOTOMOD 5. Resource System Share1\ Share2\ Share3\ \\Server2\\Server1 Share1\ Share2\ Share3\ Data distributed over multiple network shares Logical virtual data tree in PHOTOMOD Resources

4. PHOTOMOD 5. Resource System Several TB of data residing in 9 network folders of 3 file-servers Resource tree in the PHOTOMOD Explorer Example: real production configuration

5. PHOTOMOD 5. Resource System Manage network configuration from a single working place

6. PHOTOMOD 5. ADS imagery processing Set of ADS Level 1 source files Necessary ADS Level 1 files for each image: *.sup*.ads*.odf*.odf.adj*.tif Camera files with interior orientation data: *.cammisalignment.dat

7. PHOTOMOD 5. ADS imagery processing Prepare ADS data Solve ambiguities appearing when copying Level 1 data from one computer to another

8. PHOTOMOD 5. Project creation. Import of orientation data 1) Obtain source images  UltraCam images with metadata  JPEG files with EXIF structure 2) Convert the imagery to MS-TIFF  Metadata is extracted into separate XML files 3) Load the converted images into PHOTOMOD project  MS-TIFF files with pyramid  XML files with metadata 4) Use metadata information  for automatic camera file creation and interior orientation  for automatic block splitting into strips and block layout creation

9. PHOTOMOD 5. Importing UltraCam metadata UltraCam metadata contains  Interior orientation parameters  Angular and linear exterior orientation parameters  GPS-time

10. PHOTOMOD 5. Creating block layout for automatic tie points measurement Source data  Survey of mountainous terrain, 600 images  Coordinates of projection centers  Relief elevation 0-1300 meters Accurate block layout helps to increase speed and quality of automatic tie points measurement

11. PHOTOMOD 5. Block layout accuracy control Point search area exceeds 2000 pixels, it may lead to tie points misfiring. It is necessary to improve the block layout  Right-click an image  Press D key to show ruler

12. PHOTOMOD 5. Improving block layout with DEM BeforeAfter SRTM DEM fragment for the site

13. PHOTOMOD 5. Show marker position in Google Maps Google Maps Google Earth Check for consistency between your project and the real world Service – Show in Google Maps Clipboard

14. PHOTOMOD 5. Show marker position in Yandex Maps Check for consistency between your project and the real world Yandex Maps Service – Show in Yandex Maps Yandex Maps

15. PHOTOMOD 5. Distributed processing Distributed processing is supported for  Converting images to PHOTOMOD format  Automatic points computing  Creation of orthophoto sheets File-server with project data Processing workstations

16. See you at Training classes on 22 nd September!
