The vanishing divide between CAD and GIS
For decades, computer-aided design (CAD) and geographic information systems (GIS) have been like oil and water. CAD users, who see their work as engineering-based, focus on very accurate measurements and high-precision placement. They view GIS as neither accurate nor precise. GIS users, who see their work as larger scale and more cartographic in nature, cannot achieve the same accuracy over large geographies.
