Design and Implementation of a Dynamic Map Template Based on Rule Combination

According to the fact that the function of existing map templates is difficult to extend and the control is not flexible enough, a dynamic map template based on combination of cartographic rules was designed. First of all, according to the characteristics of cartography, the cartographic rules contained in each cartographic link were summarized, and then the dynamic map template applied to the whole cartographic process was designed by using cartographic rules as the basic unit, and finally through converting the user's cartographic operations into the cartographic rules and the organic combination of cartographic rules, a dynamic map template was constructed. Compared with the traditional map template, the dynamic map template has strong hierarchical and scalability, which helps to simplify the cartographic process and ensure the scientificity of the user's actions.
