| Description | The author has identified the following significant results. ERTS-1 imagery has been used to monitor the snow melt in central Alaska. Channel 5 was found to give the best results. The VP-8 analyser was utilized to obtain false color images of grey scales and the built-in planimeter with computer was used to obtain quantitative results. It was found, that the snow cover increased at high altitudes from mid-February to the beginning of May, while at lower altitudes, there was an increase from 19 Feb. to 27 March, but a decrease to 2 May, as the melting had started. Two aerial stereo flights were used as ground truth measurement of the ERTS-1 imagery. It was found that the snow cover increased with increasing altitude as well as with a northerly exposure, a result to be expected. |
