GEOG 506, Advanced Geographic Information Science Projects for 2015


Welcome to another year of GEOG 506 projects, ranging from Smart Cities to geospatial ontologies for agriculture. This year we had eleven. Here are the abstracts, with names, (GIScience field) and Project Title

Multi-Scale Change Detection Research of Remotely Sensed Big Data in CyberGIS

Jin Xing and Renee Sieber

Big remotely sensed data, the heterogeneity of satellite platforms and file formats along with increasing volumes and velocities, offers new types of analyses. This makes big remotely sensed data a good candidate for CyberGIS, the aim of which is to enable knowledge discovery of big data in the cloud. We apply CyberGIS to feature-based multi-scale land use/cover change (LUCC) detection. There have been attempts to do multi-scale LUCC. However, studies were done with small data and could not consider the mismatch between multi-scale analysis and computational scale. They have yet to consider the possibilities for scalar research across numerous temporal and spatial scales afforded by big data, especially if we want to advance beyond pixel-based analysis and also reduce preprocessing requirements.
