Method and system for using raster images to create a transportable building database for communications network engineering and management

Abstract

A Building Database Manipulator to build databases for a variety of physical environments including definitions of buildings, terrain and other site parameters, by scanning in or rapidly editing data. Raster scans may be entered or object files in various formats may be used as input. Detailed information is stored in the drawing database about the object's location, radio frequency attenuation, color, and other physical information such as electrical characteristics and intersections of the object with the ground, floors, ceilings, and other objects when objects are formatted in a drawing. The formatting process is strictly two-dimensional in nature, but the resulting drawing is a true three-dimensional environment. The user sees the three-dimensional building structure by altering the views. The resulting database may be used in a variety of modeling applications, but is especially useful for engineering, planning and management tools for in-building or microcell wireless systems. Grouping objects in layers allows for simultaneous conversion of all objects in one layer to have certain predetermined attributes (e.g., converting objects to be made from glass versus cement; converting objects within a layer to have a uniform, smaller or larger, height or width dimension).
