&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;Unstructured cells provide detailed structural information about cells.  Unstructured cells are particularly useful for high-resolution grids that must cover detailed topography -- for instance numerically generated &amp;quot;unstructured triangular&amp;quot; [[GENIE:Gridspec:Diagrams:Discretisation|discretisations]].  Vertices are specified using an appropriate point type, the only available one of which is currently a geo-referenced type consisting of geographic longitude and latitude coordinates.&lt;br /&gt;

''Since vertices are likely to be shared between cells, it may be more appropriate to associate vertices with a tile instead of a cell, and reference the vertices from cells instead (a similar thing is done for edges).  This will avoid storing duplicate vertex data.''&lt;br /&gt;
