PHOTOMOD 5. Project creationPHOTOMOD 5. Project creation. . Import of orientation dataImport 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

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
