Type I Progress ReportERTS-A
a. Title: A Study of Morphology, Provenance, and Movement ofDesert Sand Seas in Africa, Asia, and Australia
ERTS-A Proposal No.: SR 131
b. GSFC ID No. of P.I.: IN 402
c. Problems relating to progress:q
The new mode of operation referred to as "dodging" in the preparation
of black-and-white prints produces material that is not useful in the
present study of dunes. It seems to degrade the images and so the sand
features being investigated are less clear than in the former products.
d. Discussion and plans-
Because of the poor quality of the "dodged" black-and-white prints,
this project plans to use color prints entirely. Color prints are excellent
because of the ease with which sand is recognized and distinguished from
other similar features.
e. Results and application:
ERTS prints received to date are being put to use as follows:
1. One color prints of each locality within our areas has been chosen for
incorporation into area color photomosaics. Assembly of photomosaics has
been started by L. F. Harris for all foreign sites, but because of erratic
coverage, only the Thar (area 8) is essentially complete. Table 1 shows
present status of photomosaics.

Because the mosaics necessarily incorporate images from many separate
passes representing various seasons, land surface and atmospheric conditions,
and because they include differences in photographic developing, the color
tones are not uniform. The completed mosaics, however, will be excellent
bases for thematic maps and for plotting wind data on overlays, especially
when used in conjunction with the Air Force Aeronautical Charts at the same
scale (1:1,000,000).
2. Duplicate color prints, along with significant black-and-white prints,
are being categorized, according to pattern, in files now being developed
by Carol Breed. A tentative classification of sand sea morphologic types
is thus emerging (table 2).
Table 2. Elements of tentative classification as entered in files
Sand sea type. Geographic area
Linear dunes (seifs) Saudi Arabia
Reticulate (fishscale) Saudi Arabia
Sigmoidal (sinuous) Gobi
Basketweave (herringbone) Takla Makan
Cluster (tassel) Thar
Star Dunes (strings of beads) Algeria
Feathered seifs Mauritania
Seifs with wide interdunes Mauritania
Fixed and degenerate dune areas South Africa
Sand sheets and streaks (ubiquitous)
Isolated valley dunes N. Saudi Arabia

a. ERTS images are superior to all previous coverage for this purpose
because all ERTS images, though from widely differing areas, are at exactly
the same scale and can be compared directly.
b. The images in these files, unlike their counterparts in the mosaics,
can easily be separated chronologically and so seasonal changes, if any, in
a particular locality can easily be observed.
c. "Ground truth," in the form of lower-altitude aerial photos, wherever
available, is being placed in the files for corroboration.
f. Reports: None
g. Changes in operation: None
h. Changes in standing order forms: None
i. ERTS Image Descriptor forms: Attached
j. Data Request forms: Attached
