Comparative Experiments of Road Extraction from Google Earth Imagery, QuickBird Imagery and IKONOS Imagery

摘要

Main roads were detected using object-oriented method from Google Earth imagery, compared with QuickBird image of the same region and the same capture time and IKONOS image of the same region. All images extract roughly the same region of main road, and also similar image segmentation parameters and establishment of the classification rule sets. Experimental results show that using Google Earth images to extract road could meet applications of less precision demanding.
