When I calculate a noisemap (or the level of noise of each of my builings using BR_PTGRID3D), I need approximately four days for a commune (aproximately 12 km² for the noisemap but the buildings and the roads surronding the commune are also taken in the calculation).
Is that normal ?
When you have calculated the noisemap of Nantes, how much time did it take ?
This last version available of 2D noisemap is the version 1.1.1 available with OrbisGIS 4.0 .However there is no documentation and there is some computation issues on this old version. We do not give support on this old version.
