TL;DR
This paper presents a deep learning approach for efficiently mapping land cover features like buildings and roads from aerial images.
Contribution
The study introduces a novel deep learning pipeline that improves the accuracy and speed of land cover classification in aerial imagery.
Findings
The DeepLabV3 ResNet50 model achieved the highest accuracy of 94.77% for land cover classification.
The proposed approach outperformed traditional UNet models in prediction scores across all classes.
ResNet50 UNet and DeepLabV3 ResNet50 models showed better performance metrics than Vanilla-UNet.
Abstract
As more aerial imagery becomes readily available, massive volumes of data are being gathered constantly. Several groups can benefit from the data provided by this geographical imagery. However, it is time-consuming to manually analyze each image to gain information on land cover. This research suggests using deep learning methods for precise and rapid pixel-by-pixel classification of aerial imagery for land cover analysis, which would be a significant step forward in resolving this issue. The suggested method has several steps, such as the augmentation and transformation of data, the selection of deep learning models, and the final prediction. The study uses the three most popular deep learning models (Vanilla-UNet, ResNet50 UNet, and DeepLabV3 ResNet50) for the experiments. According to the experimental results, the ResNet50 UNet model achieved an accuracy of 94.37%, the DeepLabV3…
