Our algorithm takes as input a standard shape-file i.e. geospatial vector data format for geographic information system (GIS) software. The input is initially coarsened in order to automatically remove unwanted channels that are under a desired resolution. A valid non-overlapping 1D mesh is then created on the sphere using the Euclidean coordinates system x, y, z. A modified Delaunay kernel is then proposed that enables generation of meshes on the sphere in a straightforward manner without parametrization. One of the main difficulty in dealing with geographical data is the over-sampled nature of coastline representations. We propose here an algorithm that automatically unrefines coastline data. Small features are automatically removed while always keeping a valid (non-overlapping) geometrical representation of the domain. A Delaunay refinement procedure is subsequently applied to the domain. The refinement scheme is also multi-threaded at a fine grain level, allowing to generate about a million points per second on 8 threads. Examples of meshes of the Baltic sea as well as of the global ocean are presented.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Fast and robust mesh generation on the sphere-Application to coastal domains","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-10 01:32:22.930669","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Delaunay triangulation on the sphere; Geophysical flows; Parallelmeshing","OtherDescriptors":null,"Notes":null,"AnaPub":2018,"MonPub":null,"DateUpdate":"2019-06-04","DateCreate":"2019-05-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000437997400003","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.cad.2018.03.002"},"refs":null,"anarec":{"AnaID":311510,"PubliDate":2018,"Pagination":"14-23","XtraPublOfAnaID":null,"ISBN":null,"Volume":"103","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42759,"SerRR":"Computer-Aided Design.
