of ice investigations using LANDSAT - 2 imagery.	 DECO
By Erkki Palosuo,
seas
In March 1975 Finnish-Swedish project of wide spread ice
a research was arranged to find the best method of using LANDSAT-2
E 7.6 - 10.0.6 2in winternavigation.
r-	 CS 0 CR- I Y6*7^,y00
The recognition of ice situation was made using different kindfn
of methods: air photography IR-scanner, SLAR-, FLAR-systems etc.
cv
A list of these arrangements is included.

a Three sets of LANDSAT - 2 coverage were received:

other methods is going on. A complete report will be ready in a
