the high-precision TIF satellite map of some regions I downloaded by myself is
superimposed on the low-precision satellite map of the world by using global

I zoomed in on parts of the map with high accuracy and panned it, the map
became blurry, like constantly superimposing an image on the same area.</span><span data-group="0-2" style="box-sizing: border-box;orphans: auto;text-align:start;

Thank you very much!</span></span></p><br></div>
