Hebrew to English Tech/Engineering Military / Defense aerial photography unit

I do not know if the ש is part of the word, or if it just precedes it and means that, but here is the overall context in my English translation --

Transferring delineation transparencies for the SAM notepad from scale to scale was moved to the photo arm to be performed with the help of their digitizer, so that cleaner, higher quality and more precise שרסוט would be obtained on a much shorter schedule.

Any ideas?
