Vectorization of Large Amounts of Raster Satellite Images in a Distributed Architecture Using HIPI

Abstract—Vectorization processes focus on grouping pixels of a raster image into raw line segments, and forming lines, polylines or polygons. To vectorize massive raster images regarding resource and performance problems, we use a distributed HIPI image processing interface based on MapReduce approach. Apache Hadoop is placed at the core of the framework. To realize such … Read more Vectorization of Large Amounts of Raster Satellite Images in a Distributed Architecture Using HIPI

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

Performance Evaluations of Vector-Raster Satellite Image Transfers through Web Services

Süleyman Eken, Ahmet Sayar, Vectorization Performance Evaluations of Vector-Raster Satellite Image Transfers through Web Services, 36th IEEE Annual Computer Software and Applications Conference – COMPSAC 2012, Izmir/Turkey, 2012. Abstract: Applications containing images include spatial and topological queries not requiring pixel-based information. In such applications, using vector representations of raster images is expected to give better … Read more Performance Evaluations of Vector-Raster Satellite Image Transfers through Web Services
