IMMI is well prepared to handle large-scale mapping project Packages and language support
such as Strategic Noise Maps and others. Calculation run
times depend on a number of factors, the most obvious
ones are number of grid points, number of sources and
propagation effects. IMMI offers a series of efficiency
