Mapping Exposed Silicate Rock Types and Exposed Ferric
and Ferrous Compounds from a Space Platform
Quarterly Report for Period 8 June - 8 September 1974
The following report serves as the sixth quarterly report for this
contract, which is entitled "Mapping Exposed Silicate Rock Types and
Exposed Ferric and Ferrous Compounds from a Space Platform." The financial
reports have been submitted monthly under separate cover.
PROGRESS
Two major activities constitute the effort for this quarter. First we
continued program preparation for utilizing data from the S191 sensor.
Second, S192 data from White Sands was processed to determine that the ERIM
software package could handle the S192 data. Also, Dr. Vincent attended
the Principal Investigators conference in July at Houston.
Programming to read the S191 standard tapes, to calibrate the data, and to
place it in a form compatible with other ERIM listing and plotting routines
continued. A tape reading module capable of reading the data from the two
tapes was written and debugging begun. (The spectral scan of S191 is formatted
on two digital tapes. The data must be read from these tapes and merged to
give data for the entire scan.) A calibration module is planned to apply
information in the title blocks to raw data on the tape to permit reconstruction
of the actual spectral radiance values. These will be written on tape in
a format compatible with existing plot and listing routines. Work on this
task is expected to be complete in the next quarter.
Data from an SL-2 pass over White Sands was processed to verify compati-
bility of the ERIM software package with the Skylab data. Scan line
straightened data were used. We found that the data and the software
package were compatible after the dimensioning of some arrays of the software
was enlarged to accommodate the larger volume of data.
In the middle of July, Dr. Robert K. Vincent attended a Principal
Investigators Conference in Houston.

PLANS
The programming of the S191 software will be completed. When S192 tapes
arrive, processing of that data will begin.
Dr. Vincent is expected to leave ERIM on October 1, 1974 to- assume
duties as president of Geospectra Corporation, Ann Arbor, Michigan. We are
processing the necessary paperwork to transfer responsibility for contract
performance to Mr. F. Thomson. Dr. Vincent will continue to be associated
with the project as a consultant.
TRAVEL
Dr. Vincent travelled to Houston in mid-July for the Principal Investi-
gators Conference.
