With the iNoise menu option ‘View | Background Maps’ you can add multiple GIS, CAD and Image (bitmap) files as Background map layers underneath your model. iNoise automatically recognises georeferenced image files that include a separate World file. Such georeferenced image files can be purchased or can be created with GIS software. However calibrating an image file yourself is not difficult at all and can be done within minutes by using Google Earth.
