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

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 Vectorization and Spatial Query Architecture on Island Satellite Images
