OPC
user support in the setup of the color image
creation to Level-3. By presenting all images
of a block, sub-assembly or strip, the user
can set the color and ensure that a ground
point has the same color, irrespective of
the image and the location in it.

The large format digital aerial images are collected
in the air by the UltraCam system so that each triggered
image is presented in 13 separate files (Level-0). The
panchromatic image is in 9 separate “tiles”
that need to get stitched, color is in an additional
4 separate files that need to be registered and added
to the panchromatic data. The transition from the raw
Level-0 data to the final Level-3 color images is by
postprocessing using Microsoft Office Processing Center
software (OPC). Since the initial UltraCam deliveries
at the beginning of 2004, we have listened to our customers
and have addressed many of their suggestions. The updates
to the OPC software, as a result, are now greatly improved.
