Abstract: Massive amounts of geospatial data require better techniques to analyse and display them. A common practice in applying statistical analysis and reporting units is represented by the regional statistical unit grids, which are used for national and European statistics and reporting. In line with the EU’s INSPIRE directive, Austria provides statistics constructed on the European Terrestrial Reference System, which uses the Lambert Azimuthal Equal Area projection (ETRS-LAEA) for spatial analysis and display. Although these units are fixed and allow comparability and replicability, there is no relation with the underlying phenomenon. In this study, we evaluate the suitability of SLICO superpixels to replace the artificial ETRF grid squares when delineating an image for further analysis and using reporting units, or for display purposes. In this approach, we minimize any further parametrization, which is introduced by many other available segmentation algorithms, and aim to replicate the ETRF grid by imposing a size constraint and using the square’s centres as seeds for superpixel generation. Keywords: SLICO superpixels, cell aggregation, multi-scale, image segmentation Published Online: 2017/06/30 09:31:33 Object Identifier: 0xc1aa5576 0x00369d9b Rights:https://creativecommons.org/licenses/by-nd/4.0/
GI_Forum publishes high quality original research across the transdisciplinary field of Geographic Information Science (GIScience). The journal provides a platform for dialogue among GI-Scientists and educators, technologists and critical thinkers in an ongoing effort to advance the field and ultimately contribute to the creation of an informed GISociety. Submissions concentrate on innovation in education, science, methodology and technologies in the spatial domain and their role towards a more just, ethical and sustainable science and society. GI_Forum implements the policy of open access publication after a double-blind peer review process through a highly international team of seasoned scientists for quality assurance. Special emphasis is put on actively supporting young scientists through formative reviews of their submissions. Only English language contributions are published.
