Land Resource Use Classification Using Deep Learning in Ecological Remote Sensing Images

Abstract

Aiming at the problems that the traditional remote sensing image classification methods cannot effectively integrate a variety of deep learning features and poor classification performance, a land resource use classification method based on a convolutional neural network (CNN) in ecological remote sensing images is proposed. In this study, a seven-layer convolution neural network is constructed, and then the two fully connected layer features of the improved CNN network training output are fused with the fifth layer pooled layer features after dimensionality reduction by principal component analysis (PCA), so as to obtain an effective remote sensing image feature of land resources based on deep learning. Further, the classification of land resources remote sensing images is completed based on a support vector machine classifier. The remote sensing images of Pingshuo mining area in Shanxi Province are used to analyze the proposed method. The results show that the edge of the recognized image is clear, the classification accuracy, misclassification rate, and kappa coefficient are 0.9472, 0.0528, and 0.9435, respectively, and the model has excellent overall performance and good classification effect.

The Use of High-Resolution Satellite Imagery to Determine the Status of a Large-Scale Outbreak of Southern Pine Beetle

“…Abdullah and others [31] found that red-edge spectral data were beneficial in detecting green attacks in trees. This study did not directly assess the attack stage, but future research could address this using PCA and training data from plot-level surveys to build neural network models to classify vegetation threats [22,32]. Early identification of tree stress would allow for mitigating measures to be taken to prevent the further spread of SPB in a forest [11].…”

“…16.09. The map comprises 12 categories, including bamboo forests, bare lands, water bodies, urban regions, paddy fields, croplands, grasslands, deciduous broad-leaf forests, deciduous needle-leaf forests, evergreen broad-leaf forests, and solar panels [ 16 ]. For this study, bamboo forests, deciduous broad-leaf forests, deciduous needle-leaf forests, and evergreen broad-leaf forests are merged into one class and categorized as forests.…”
