I don't have any way to make that exact grid. Both Seagrid and my Fortran code are based on a routine called 'rect' which requires your domain to map to a rectangle. Our Python tools instead use a routine called 'gridgen' which can have a more complex boundary. However, I don't know how to get gridgen to make curved edges between the boundary points.The model delft3d has a more capable grid generation tool which appears to be called RGF-grid.

Lyon Lanerolle has had good luck with using it to make ROMS grids. I'm not sure what the licensing and costs are on it. If you are after a GUI tool easy to use and if you use Windows, Delft3D RGFGRID may be your best option so far. You can create detailed curvilinear grids using the tool.Now you can even save grids as ROMS netcdf grid file with RGFGRID. But you will need to tweak a bit after you create a ROMS grid file (I had to do that a while ago for a older version of RGFGRID). You can get RGFGRID for free of charge until Deltares releases its source code (not sure when).You can request the tool from the following site.There is a Linux version as well, but it was not stable when I tried it; whereas, RGFGRID for Windows was (and probably still is) stable.Also, there is a tool called pygridgen and according to the web site, it comes with GUI.

I have never used it, though. You might want to check it out.Hope this helps.DJ.

Arguments inFlRaster group file with the file names of the input time-series.outFlRaster group file with the file names of the output time-series.stepNumber of images taken for each summary.If a value is not supplied, the summary is made on the complete time-series.funSummary function SUM, MAX, MIN, MEAN, COUNT, RANGE, SD, VAR,MEDIAN.refThe reference image.order'FIRST' or 'LAST'; to find the first or the last occurrence in the time-series.silentlogical; if TRUE, comment and non-fatal CPL driver errors are suppressed.Any unmatched parameter will be passed to the writeGDAL function. DetailsAny summary can be computed for the entire set, or for a subset of images.For example, let a time-series made of 36 images representing monthly NDVI.The maximum NDVI found at each grid cell could be computed for the entire series (step not specified), for each year of the series (step = 12), or quarterly (step = 3).The corresponding summary images are then saved to raster files.rgf.when compares a reference image with the images in the time-series (or a subset of it), and returns a composite image where each grid cell contains the order-number at which its reference value is found.
