Edge Matching
Edge matching is simply the procedure to adjust the position of features that extend across typical map sheet boundaries. Theoretically data from adjacent map sheets should meet precisely at map edges.

A quasar is an enormously bright object at the edge of our universe. The word quasar, short for "quasi-stellar radio source" was named in the 1960s when quasars were first detected.
Fill the hole with epoxy resin and insert the disk, with the resin slightly built up around the edge.
The actual edge of each quad image is to the left and right of the seam. Therefore, you will still see some sort of neatline, but you will not see the boundary of the images.
For example, fully one-third of a map lies within 10% of an edge. If the map is 24 inches wide by 36 inches tall, this means that one-third of the map will be within 2.4 inches of the left or right border or within 3.
