Sample segments of ground-verified land cover data |
|
collected in conjunction with the USDA/ESS June |
|
Enumerative Survey were merged with LANDSAT data and |
|
served as a focus for unsupervised spectral class |
|
development and accuracy assessment. Multitemporal data |
|
sets were created from single-date LANDSAT MSS |
|
acquisitions from a nominal scene covering an eleven- |
|
county area in north central Missouri. Classification |
|
accuracies for the four land cover types predominant in |
|
the test site showed significant improvement in going |
|
from unitemporal to multitemporal data sets. Transformed |
|
LANDSAT data sets did not significantly improve |
|
classification accuracies. Regression estimators yielded |
|
mixed results for different land covers. Misregistration |
|
of two LANDSAT data sets by as much and one half pixels |
|
did not significantly alter overall classification |
|
accuracies. Existing algorithms for scene-to scene |
|
overlay proved adequate for multitemporal data analysis |
|
as long as statistical class development and accuracy |
|
assessment were restricted to field interior pixels. |
