No they are not, GE2KAP creates a chart depending on the real coordinates of the GE viewport, which obviously can later be quilted with other charts
"exactly". The plugin works exactly in the opposite direction - it knows what the chart viewport contains exactly and asks GE to be so kind and show something as close to it as possible - the problem is that the only possible way to do it is by the centerpoint and height of the camera
above ground, which combined with the GE view not being Mercator and to WGS84 datum makes it impossible for the two areas to fit. The plugin view is "live", but at a price
... Of course you get the best if you combine the two wisely.
