SUMMARY FOR REPORTING PERIOD
GEMS Outputs, Post-Analysis
The GEMS Lab relocation-reassembly at Valley Forge during this period
precluded any on-line analysis. However, in anticipation of the facility
move, a rather concerted set of runs initiated during the last visit to
Valley Forge by Jene McKnight was continued, resulting in the generation of
a series of output mag tapes. The offline printouts from these tapes
could be made downstream from the GEMS, per se, in the peripheral support
computer facility. For the ERTS scene 1234-18021 using the NDPF MSS
Bulk Standard Color Transparency, the 12 themes printouts for the follow-
ing urban regions were thus generated:
1. West-Central Los Angeles
2. Long Beach
3. Glendale-Burbank
4. San Gabriel Valley
5. San Fernando Valley
6. Lancaster-Palmdate
7. Oxnard-Ventura
8. Bakers Field
These regions cover areas within the geographic jurisdictions of the
following counties: Los Angeles, Orange, San Bernardino, Ventura, and
Kern.
The offline printouts superpose themes that have been individually recorded
on the slides taken on-line from the combiner TV screen. Here, preliminary
analysis was described in the previous Type 1 Report, July, 1973. While
the single theme and theme-plus-background slides facilitate analysis of
individual themes in relation to reference/ground truth data, the multi-theme
printouts enable inter-themes comparative analysis of both same-sub-scene
themes as well as different sub scenes/spectrally equivalent themes.
Underflight 73-108 Coverage-Data
Early in this reporting period, an underflight was flown by NASA AMES
on July 2, 1973 with an A-I configuration camera aboard a U-2. The rock-
ing mode operation, with flight-lines mostly over the L.A. county main-
land, nevertheless presented oblique coverage over most of the Test Site
SR 124 while also giving additional orthogonal coverage for areas adjoin-
ing the flight-line groundtracks. The extensive amount of imagery from
the 24" lens cameras using Aerial Color SO 242 film and 6" lens using
Ektachrome Aerographic SO 397 film was arriving at both COLA-RPC and
GE-SD locations towards the end of the reporting period. As had been
anticipated even during the proposal write-up/data request scheduling,
cloud-cover smog-occurance problems present problems for summer cover-
age. In fact, the inclement weather during the desired flight period
necessitated rescheduling of an earlier begun underflight to be completed
on a subsequent date. As feared, the nearest-date ERTS coverages (June 30
and July 18) also have had severe cloud cover over the urban regions with
the scenes of interest.
Plan for Next Bi-Monthly Period
Evaluation of the outputs from the GEMS runs reported above will be
continued. Rather than continued analysis of film products only on the
GEMS, the shift to analysis of the digital tapes for scenes already anal-
yzed in transparency formats will be begun during the coming months.
This will initially be attempted on the GSFC-LARS Remote Terminal, while
the GE Image 100 system at Daytona Beach is expected to be operationally
available towards the end of the next period.
