geometry.xsd A GML conformant schema for specialised geometries for geoscience Copyright (c) 2005 CSIRO - see https://www.seegrid.csiro.au/twiki/bin/view/Xmml/LegalNotices#Software_Notice More flexible, and potentially more compact version of a set of triangles, directly derived by restricting the general composite provided by GML, allowing either gml:Triangle or geo:Triangle as members Represents a triangle as a surface with an outer boundary defined by references to three Points. Note that this is a polygon (subtype) with no inner boundaries. Relative to a right-handed coordinate system the vertex sequence is counter-clockwise around the positive normal vector A | 0__| __2 \ | / \ / 1 Represents a quadrilateral as a surface with an outer boundary defined by references to four Points. The points must be co-planar. Note that this is a polygon (subtype) with no inner boundaries. Relative to a right-handed coordinate system the vertex sequence is counter-clockwise around the positive normal vector A | 0__| __3 | | | |_____| 1 2 triMembers contains triangles, each of which is described using either the gml or xmml forms. quadMembers contains quadrilateral patches, each of which is described using either the gml or xmml forms.
