A critical convergence of software, data, and data models is opening up a new frontier for computer-assisted mass appraisal (CAMA) management. This convergence will simplify CAMA updates, allow better integration with spatial data, automatically perform appraisal change detection, and allow for the creation of truly integrated management processes. A key to this convergence is the automated spatial registration of CAMA sketches with a new form of property imaging called lidar—light detection and ranging. Recent advances with lidar have led to new, powerful tools that accurately place the CAMA sketch in real-world space while simultaneously performing change detection.
