Temporal Signature Matching for Land Cover Classification
نویسندگان
چکیده
Objects on the surface of earth describe unique patterns in time and this is exploited in the proposed land cover classification method enumerated in this paper. The applicability of various distance measures to reasonably find similarity or dissimilarity between time series vegetation index patterns for land cover classification is demonstrated. These distance metrics have inherent advantages for satellite image classification as land use practices such as field crops/vegetation exhibit temporal shifts from pixel to pixel based on the geographic location. Experimental results on time series of MODIS EVI (250m) and AWiFS derived NDVI (56m) demonstrate the applicability and validate the performance of the proposed method. The classification method is also compared with k nearest neighbor (kNN) and support vector machine (SVM) classifier to understand its utility. * Corresponding author.

Land cover/land use categories are relevant components in land management. Understanding how land cover/land use change over time is necessary to assess the consequences of humans and natural stressors on the earth’s environment and resources. The aim of the study was to map and monitor the spatial and temporal change in land cover/land use for the periods of 1977, 1991 and 2016 and to predict ...
