1. A computer implemented method for creating, formatting or editing a database for representing a three dimensional physical environment where a wireless communications network will be deployed, comprising the steps of: accepting at least one raster image representing a physical environment in which an in-building or campus communications network is or will be deployed; verifying the sufficiency of said at least one raster image to provide a useful definition of said three dimensional physical environment, said verifying step producing a verified set of data defining said three dimensional physical environment, wherein said verifying the sufficiency step includes scaling said at least one raster image; notifying a user of results of said verification of sufficiency; using the resulting verified set of data to generate at least one formatted drawing or a set of formatted data which includes at least one or more objects for use in and being transportable to a communications engineering or network management application; and rendering a three dimensional view representative of said physical environment using the drawing or set of formatted data having the at least one or more objects.
