I am, strangely enough, highly spatial and tested off the charts for it when I was younger. I can do exactly what you describe, with a high degree of precision.

I am, strangely enough, highly spatial and tested off the charts for it when I was younger. I can do exactly what you describe, with a high degree of precision. I do this mainly by elimination, which is likely due to the fact I can't consciously perceive the imagery, but only get a feeling if it is "right" or not. One way I put it to a visualizer recently was that I am not conscious of seeing the map, but I am definitely operating on the mesh. The way he described it was that he was actively seeing the map, overlayed on the model, as if it were a screen in mind. He waved vaguely to "up here" where it "was".
