With the coming of interactive maps technology,there has been a huge change in both the perspective of graphical rendering and the user-friendly browsing experience.Therefore,only by establishing a new user-centered map visualization mode with advanced graphics rendering technology can users be assisted in carrying out visual anal-ysis activities.In this paper,an adaptive projection scheme based on two-dimensional GIS(Geographic Information System)is proposed,which innovatively takes user preference and projection characteristics as control parameters to form a prediction model that can effectively match suitable projection.In the experimental part,the influence on the results and performance of the hidden Markov projection prediction model were analyzed by controlling the preset user preference and the proportion of quantitative projection characteristics,and the feasibility of the adaptive projection mode was verified from various aspects through statistical sampling.
