This data series contains 3724 2009 1-foot natural color digital orthoimage tiles. The data cover almost all of Boundary County, Idaho, a portion of Lincoln County, Montana, a portion of Pend Oreille County, Washington, and north of the border into Canada. These data were provided to INSIDE Idaho by the U.S. Geological Survey. For this dataset, the natural color orthoimages were produced at 0.3-meter pixel resolution (approximately 1-foot). The design accuracy is estimated not to exceed 6 meter horizontal RMSE for locations within the United States. Each orthoimage provides imagery for a 1500-meter by 1500-meter block on the ground. The projected coordinate system is UTM with a NAD83 datum, spheroid GRS80. There is no image overlap between adjacent files. The naming convention is based on the U.S. National Grid (USNG), taking the coordinates of the SW corner of the orthoimage.
