Orthophotos combine the image characteristics of a photograph with the geometric qualities of a map. The primary digital orthophotoquad (DOQ) is a 1-meter ground resolution, quarter-quadrangle (3.75-minutes of latitude by 3.75-minutes of longitude) image cast on the Universal Transverse Mercator Projection (UTM) on the North American Datum of 1983 (NAD83).The geographic extent of the DOQ is equivalent to a quarter-quad plus The overedge ranges a minimum of 50 meters to a maximum of 300 meters beyond the extremes of the primary and secondary corner points. The overedge is included to facilitate tonal matching for mosaicking and for the placement of the NAD83 and secondary datum corner ticks. The normal orientation...

There were three major eruptive pulses on July 22, 1980. They begin at 17:14, 18:30 and 19:02 PDT. Slides no. 5 through 25 were taken between 18:25:20 and 18:26:30 This sequence was taken while moving counter-clockwise from the north to the west flank of Mount St. Helens at a distance of about 7 miles and while changing elevation from about 10,000 to 12,000 feet. Approximately 3 seconds after slide no. 20. Skamania County, Washington. (Photo by J. Vallance, USGS) View of...

February 9, 1971, San Fernando Earthquake. Demonstrating the vulnerability of the modern urban society to the damaging effects of a nearby earthquake. Oblique aerial view of collapsed highway over- passes and bridges at the interchange of the Foothill and Golden State Freeways. Because the earthquake occurred early in the morning, only three deaths resulted from this damage. However, the principal highway link between northern and southern California was temporarily cut, and traffic had to be re-routed for several months. See also California Earthquake image 005. Photo by R. E. Wallace. Los Angeles County, California. 1971. Published in U.S. Geological Survey Professional Paper 1360 as Figure 2-B. 1985.
