This paper discussed the model design and experiment for linear dynamic annotations in digital map system. The digital differential analyzer (DDA) model was designed for optimum solutions of annotation point position selection and annotation overlay identification. The model was successfully used in the Beijing Digital Atlas, China Regional Development Management System, etc. All practice shows that it has made a great effect.
