Polygons representing 1/100th of a USGS 7.5-minute Quadrangle.
DOGAMI
This polygon feature class consists of 1/100th divisions of USGS 7.5-minute quadrangles covering the state of Oregon.
This dataset consists of 1/100th divisions of USGS 7.5-minute quadrangles covering the state of Oregon. It is utilized by the SP-42 Toolbox to format output 10-foot and 3-foot contour datasets which will allow for easier redrawing of the contour lines in ArcGIS. These contour datasets provide a base map for assisting the landslide geologist in delineating landslide deposit polygons as part of a landslide inventory.

This dataset consists of polygons that are each 1/100th of a United States Geological Survey (USGS) 7.5-minute quadrangle. It was checked to verify that the number of polygons were correct.
This dataset covers the entirety of the extent of the Oregon state boundaries.
The positional accuracy of this dataset is based on the original USGS 7.5-minute quadrangle dataset within the state of Oregon. For more details about the positional accuracy of the USGS 7.5-minute quadrangle dataset, visit https://mrdata.usgs.gov/metadata/quad24.faq.html
The creation of the USGS 7.5-minute quadrangles is based on the Ohio grid system. The Ohio code grid system splits a 1-degree latitude x 1-degree longitude grid block into sixty-four 7.5-minute quadrangles. The Ohio code values are derived from the latitude and longitude of the SE corner of the 1-degree x 1-degree block and an assigned grid number.
