While the maps are compilations from available literature and data, their main purpose is to act as overview maps. Thus incorporating and harmonizing existing data is the main purpose. The maps are prepared as vectorized and georeferenced files that are easily incorporated into Geo-Information Systems. All relevant information, like references or sources, are provided with the files so that the origin of data remains clear and citeable. Thus, easy and straightforward use is guaranteed. They are published under a Creative Commons license (CC-BY 4.0) for free use. Each map is available in two versions: 1. vectorised shapefiles including landmasses, oceans, and ice shields2. an overview of the source data. Contributing Version control Copyright workgroup Currently available maps Available additional data Contributing The project is open for further refinement and contributions. Therefore we encourage colleagues to provide higher resolution data for certain areas or engage in discussions for improving the maps. Preferably we are interested in published maps. Until we have established an open format for discussions, please get into contact with us by e-mail: sonja.grimm@zbsa.eu Version control EPHA is constantly in development and refinement. Hence it is highly recommended to note the version of a respective map used. Copyright Since EPHA is a compilation from various sources, different copyrights may appear. Therefore it is mandatory to cite the respective literature if you use maps or parts of them. EPHA maps are licensed under the Creative Commons Attribution 4.0 International License (CC-BY 4.0).
