Pdf Geomorphological Change Detection Using Object Based Feature When challenges related to interpolation techniques are tackled, stratified obia of multi temporal lidar data sets is a promising tool for geomorphological change detection, and affiliated applications such as monitoring risk and natural hazards, rate of change analyses, and vulnerability assessments. Our objective is to test stratified object based segmentation and classification on a multi temporal 1m resolution lidar dataset and to prepare and evaluate a geomorphological change detection layer in a mountainous area suffering from slope instability processes.

This study proposes a novel change detection method implementing change feature extraction using convolutional neural networks under an obia framework. to demonstrate the effectiveness of our proposed method, we compare the proposed method against benchmark pixel based counterparts on aerial images for the task of multi class change detection. Geographic object based image analysis (geobia) refers to a category of digital remote sensing image analysis approaches that study geographic entities, or phenomena through delineating and analyzing image objects rather than individual pixels (castilla and hay 2008; blaschke 2010).
