3D Visualization and Spatial Data Mining for Analysis of LULC Images
This addresses the need for better analysis tools in remote sensing for domain experts, though it is incremental as it combines existing techniques like K-Means clustering with 3D visualization.
The study developed a 3D visualization tool using spatial data mining to analyze Land Use Land Cover images, enabling user involvement in classification for improved confidence and understanding, demonstrated on high-resolution satellite imagery from Latur district, India.
The present study is an attempt made to create a new tool for the analysis of Land Use Land Cover (LUCL) images in 3D visualization. This study mainly uses spatial data mining techniques on high resolution LULC satellite imagery. Visualization of feature space allows exploration of patterns in the image data and insight into the classification process and related uncertainty. Visual Data Mining provides added value to image classifications as the user can be involved in the classification process providing increased confidence in and understanding of the results. In this study, we present a prototype of image segmentation, K-Means clustering and 3D visualization tool for visual data mining (VDM) of LUCL satellite imagery into volume visualization. This volume based representation divides feature space into spheres or voxels. The visualization tool is showcased in a classification study of high-resolution LULC imagery of Latur district (Maharashtra state, India) is used as sample data.
