Training 2

For example, as the 3DIS passes above the tree, the branches will dominate the image. At a point on down the flight line (or an adjacent flight line), the edge of a different image will “see” the road surface under the tree. An ortho-based system will attribute every point with the single, top-most color. In our example of a non-3DIS scheme, all points, including the road point, would be colorized with the top-most tree point from the orthomosiac. As you can imagine, this significantly degrades the value of colorization.
