Multispectral and Texture Feature Application in Image-Object Analysis of Summer Vegetation in Eastern Tajikistan Pamirs
by Eric Ariel L. Salas, Kenneth G. Boykin and Raul Valdez
Abstract: We tested the Moment Distance Index (MDI)
in combination with texture features for the summer vegetation mapping
in the eastern Pamir Mountains, Tajikistan using the 2014 Landsat OLI
(Operational Land Imager) image. The five major classes identified were
sparse vegetation, medium-dense vegetation, dense vegetation, barren
land, and water bodies. By utilizing object features in a random forest
(RF) classifier, the overall classification accuracy of the land cover
maps were 92% using a set of variables including texture features and
MDI, and 84% using a set of variables including texture but without MDI.
A decrease of the Kappa statistics, from 0.89 to 0.79, was observed
when MDI was removed from the set of predictor variables. McNemar’s test
showed that the increase in the classification accuracy due to the
addition of MDI was statistically significant (p < 0.05). The
proposed method provides an effective way of discriminating sparse
vegetation from barren land in an arid environment, such as the Pamir
Mountains.
