An automated technique to determine spatio-temporal changes in satellite island images with vectorization and spatial queries

Abstract. For spatio-temporal and topologic analyses, vectorial information (car- rying coordinate values defined as point sets) gives better information than its raster (grid of pixels) counterpart. The study presented in this paper is based on (i) recogni- tion and extraction of an island object in a set of digital images captured by LandSat-7 satellite and … Read more
