Comparing Igage and Competitor's Scans

It is difficult to directly compare the competitor's scans with the Igage All Topo Scans. The All Topo scans are effectively 250 DPI scans, while the competitor's scans are about 112 DPI scans.

Zooming the competitor's to match Igage image size:
Igage (100%) notice how clean the contour lines and text appear:
 

Competitor (200%) Notice the compression artifacts

All Topo Maps are usable when greatly magnified since they are compressed with loss- less compression. The competitor's maps are worthless when zoomed in. Here are actual screen shots from the two programs:
