7.1.3 Wrap Check

When drawing a satellite image on a projection of the entire world, there is the possibility that the polygon drawn to represent a single data point may straddle the most extreme latitude or longitude line, thus needing to appear on both sides of the projection. There is code built into SatView to detect this case, but it is computationally expensive. Since it is not always necessary, the user is given the option of turning it off for the sake of speed. If streaks appear across the screen when drawing a satellite image, simply turn Wrap Check back on.
