Plate 2. Comparison of right angle road intersection for inter-scene registration

Cursor positioned at center of 1995 road intersection. Cursor at same pixel/line position in 1985 imagery.
The road intersection in the older image (right) is satisfactory. The cursor offset is less than one pixel. The road to the right appears to have been narrower in 1985 which accounts for the 1/2 line offset in the y-axis. The x-axis is well-aligned with less than 1/2 pixel offset. Note: we do not consider the smaller road to the left in this evaluation. It lacks clarity and does not approach the intersection at a right angle.
