Statistical differences between the directional 
distribution of dikes interpreted from radar and 
those interpreted from LFC photos are strongly ef 
fected by radar look direction. The classes in a 
range of 20° around the radar, look direction are 
strongly underrepresented on radar whereas perpendi 
cular to it the directions are overrepresented com 
pared to the LFC image. 
The sun direction azimuth with sun elevation of 
49°, seems neither to have much influence on enhan 
cement of lineaments on LFC photos perpendicular to 
this direction nor on suppression in frequency for 
directions parallel with the sun azimuth. The influ 
ence of radar penetration does not seem to contribu 
te much to the differences observed. 
The study is past of the NASA/JPL SIR-B experiment 
and carried out in the context of ITC research 
project 743401. 
As a member of the SIR-B science team, the author 
wishes to acknowledge the valuable co-operation of 
C. Elachi, principal investigator of the SIR-B pro 
ject, and his JPL co-investigators. Because of poor 
data collection over the author's own test site, he 
was given the opportunity by T. Dixon of JPL to 
study the Sudan/Egyptian radar strip and Large 
Format Camera photography. N.H.W. Donker of ITC 
assisted with the statistical analysis. Drawings 
were made by Lutke Schipholt and the manuscript was 
typed by Anne van der Linde.
