No TIN support is unfortunate. I guess it means that I need to pick a single compromise spatial resolution, and that will cause all sorts of problems near the coastal boundary.
The TIN consists of two types of ascii files: 1) grid details: node, lat, long, code for type of node (wet, coastal, boundary, etc), approx depth, and pointers to linked nodes 2) temperature and salinity files: 52 specified depth levels (-5000m to 0m), rows of T/S data at the 52 levels for all nodes Do I recall some TIN support in the GDAL library somewhere? (I can no longer find it) >From the paper in GEOPHYSICAL RESEARCH LETTERS, VOL. 35, L22606, doi:10.1029/2008GL035152, 2008 "Dynamic ocean topography for the northeast Pacific and its continental margins M. G. G. Foreman, W. R. Crawford, J. Y. Cherniawsky, and J. Galbraith" "... the triangular grid was constructed with the software package GRIDGEN and its predecessor TRIGRID [Henry and Walters, 1993]. It has 97,959 nodes, 169,869 triangles and a resolution that varies from 100 m in some narrow coastal channels to 70 km in the deep ocean. The grid is essentially a combination of that used by Foreman et al. [2000a] for the northeast Pacific with the high resolution Vancouver Island grid described by Foreman et al. [2004]. Model depths were computed by a smooth interpolation of data from the Canadian Hydrographic Service, Smith and Sandwell [1997], National Oceanic and Atmospheric Administration (NOAA) charts and GEODAS hydrographic survey data." --terry ------------------------------ Date: Tue, 30 Aug 2011 08:18:39 +0200 From: Andrea Aime <[email protected]> Subject: Re: [Geoserver-users] Trainagular Irregular Network (TIN) Documentation?

GeoServer does not support TIN data as far as I know. To publish it you probably have to turn it into a raster. Out of curiosity, what data format is the TIN stored in?
