reprojection using proj4 strings
interpolation of scalar gridded data
interpolation of vector gridded data using constant and variable vector length
interpolation of lat/lon coordinates to projection (e.g. GHRSST satellite data)
automatic detection of output projection axes using the maximum bounding-box
automatic detection of spatial vectors
linear time interpolation
vertical interpolation to height or pressure levels (lin, log(p), log(log(p))
pre-processing of data for vertical levels: theta2T, add4Dpressure
pre-processing of data: fill 2d data
