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

PHOTOMOD 5. Importing UltraCam metadataPHOTOMOD 5. Importing UltraCam metadata

UltraCam metadata contains Interior orientation parameters Angular and linear exterior orientation parameters GPS-time

PHOTOMOD 5.PHOTOMOD 5. Creating block layout for automatic tie points Creating block layout for automatic tie points measurementmeasurement

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
