CADD technology has become the preferred method for the preparation, distribution, storage, and maintenance of architectural and engineering type drawings. With CADD systems, graphic three-dimensional or two-dimensional digital data are placed on various drawing layers that can be selectively displayed and edited. To improve the speed and accuracy of base map production, CenterGeo has developed and/or implemented numerous “field to finish” mapping techniques. We utilize the recent survey and CADD software to provide high quality maps in various formats.
