A netCDF convention to do a similar action has been developed for atmospheric research aircraft. You can read about it at http://www.eol.ucar.edu/raf/Software/netCDF.html Each measurement or calculation is stored as a 2D variable. The first dimension is time at once per second. It can be unlimited for a realtime growing file. The second dimension is samples per second. There is also a third dimension for vector data, but it sounds as if you don't need that. The use of two dimensions allows data for different rates to be stored. The beta tested netcdf-4 will allow more than one unlimited dimension. Magnus Hagdorn wrote:
Hello world, we are currently considering to use the netCDF library to store data coming from our instruments. The data represents multiple variables together with a timestamp of the measurement. Some variables are updated more often than others. Sample rates are of the order of 100Hz to 1000Hz. I was thinking of storing the data as a table with 3 columns, timestamp, ID and value together with some appropriate header. Do you think this is a reasonable idea, are there other more suitable standard formats?
