It was working well every time in the past and now for some reason it's not. Adding netCDF to Geoserver. We distribute our data sets only in NetCDF, which is an internationally recognized climate data standard. What makes PostGIS raster data particularly interesting, is that since each tile can have various standard database columns, you can segment it in your data source. The good news is that it works with the raster classes too! You simply pass your Raster___ object as the shp argument to the tm_shape() function, and then add a tm_raster() layer like this. Raster Data Structure • ArcGIS can create a multidimensional layer from NetCDF. The raster image marker symbology permits customization of width, height, image ratio, rotation, and opacity. Using coordinate variables works for both of them but the product comes out distorted. It seems that turning my data into a NetCDF file outside of R so R can use it as a rasterStack may be the way to go, but I'm having trouble working out how to gdal doesn't quite seem to grasp that I want to make a NetCDF file with 40,000 layers, for example.
