This 'third progress report gives initial results on Landeat ­
2 data received in the correspondind period. During this period 3 
scenes taken,on December 19, 1975, were received and evaluated. 
The Four CCTS previoualy ordered have been received and treate­
ment has began.

1 - INTRODUCTION 
This report covers the second quarter of 1976 during


which number of significant new techniques has been made opera­

tional using, LANDSAT-1 data.


Over the same period, LANDSAT-2 data has been recei­
ved and reformated to our databank standart (assembly of 4 stripc 
to single scene recording) on direct-access units. 
Interpretation, ULaseification and mapping of 
LNDSAT-2 data has been initiated, singly or in connection with 
LANDSAT-A data, with emphasis on coastal areas, extending seaward 
to the extent of coastal sediment transport and landward into 
saltmarshes, dunes and polders.


-2­

2 - TECHNlIQUES 
2-1 4 strip records were copied on disk using


3240 pixel/line format to facilitate data processing, especial23


in areas bisected by strip borders.


2-2 : Various improvements were carried out on oujr


supervised automatic mapping procedures (using IBM 360 and


Benson Offline Plotting System) to save program execution time.


2-3 ,Time sharing (Tektronix 4013 output7- linked


to IBMI 360) : further development of the FRACAM package have no


made this unsupervised interactive classification system fully


operationnalo


2-4 : A smoothing technique is being tested based on


using each pixel in the mapped outpua.from programs (2-2 and 2-3


as the centre of a rectangular or square matrix and replacing


this pixel with the modal signature found in the surrounding


matrix.


3 - ACOIILISIFhmNTS 
3-I C-round truth - fot LANDSAT-2 data, we have


continued to draft maps of coastal areas showing directions of 
currents and tide heights (following pages). Times given are 
TU.u (Fig, 3o1,1o to 3.13). 
3-2 - Application of.automatic cartography of


ITUDSAT-1 data to the Brouage'iarsh test-site (see Fig. 3.2.1)


Some caracteristic areas of the marshes have been isolated 
and investigated. Remote sensing techniques provide a "neotaxo­
nomy! wvIhioh is usually different and complementary to the 
customary visual taxonomy, ­

5 - DA L D DELIVERY 
Since the last report, 3 frames of B/W,70 mm imagery


have been reoeived. Despite certain delays we find that data


has been reaching us more regularly (2 to 3 months after covera­

ge),,


The four COTS ordered 5urirg the last quarter of 1975


have been received and their interpretation has begun.
