Abstract: Beyond the wide applicability of quadtrees in image processing and spatial information analysis there may be numerous further applications in astronomy. Some of these practicable applications based on quadtree representation of astronomical data are presented. Statistics of nodes at different levels may provide useful information on spatial structure of astronomical data in question. A sampling method based on quadtree representation of an image is proposed, which may prove to be efficient where observations were carried out previously either with different resolution or/and in bands.
