Conclusions 
Based upon several years of experience of using MSS data we may summarize 
the experiences as follows: 
- the availability and overall quality of the digital MSS data from 
the Landsat system has been of significant importance for the intro- 
duction of computer techniques to the user community 
- for Swedish inventory problems forest inventory and land use mapping 
seem’ to be promising applications from Landsat data. Classification 
accuracy should however be improved,either by applying multidate ana- 
lysis, improved resolution and/or systematic use of complementary 
databases 
- operational uses of Landsat data in forest inventory and land use 
mapping will be of significance in Sweden when the improved resolu- 
tion of Landsat D will become available 
- the airborne MSS data have higher cost figures, more severe geometri- 
cal and radiometrical distortions than Landsat data 
- as a result of higher distortions classification accuracy for the air- 
borne data decreases drastically towards the edges - the scan-angle 
effect 
- in the central region the accuracy of the classified airborne MSS data 
is significantly higher than for Landsat data due to the better reso- 
lution 
- the airborne MSS data collection system will probably not be important 
for operational work, due to costs and distortions. As a research tool 
the technique however is useful.
