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

Vectorization and Spatial Query Architecture on Island Satellite Images

Süleyman Eken, Ahmet Sayar, Vectorization and Spatial Query Architecture on Island Satellite Images, Procedia Computer Science Journal (ISSN: 1877-0509) by Elsevier, 2012 (Accepted). Abstract: Vector data structure produces smaller file size than raster image because a raster image needs space for all pixels while only point coordinates are stored in vector representation. Raster-to-vector conversion, i.e. … Read more
