This is a mosaic of black and white orthorectified aerial photos of Montana and Yellowstone National Park that were taken predominantly in the 1990s. Some areas in Missoula, Lake, and Sanders counties were photographed in 2000 through 2003. The mosaic footprint layer has an attribute field called Image_Year that gives the year the image was taken and a field called Image_Main_Date that gives the first date from the USGS metadata for the image. Some images contain data from multiple dates, but there is no indication of which parts of an image may be from a different date than the Image_Main_Date.The images that form this mosaic were obtained by the Montana State Library between 1998 and 2004 from the U.S. Geological Survey and converted from UTM coordinates to State Plane coordinates. In order to allow zero to represent no-data values for the resulting images, all pixels with a value of 0 were assigned a value of 1. The images of the mosaic are all in Montana State Plane coordinates, units meters, datum NAD83. The coordinate system of the image mosaic is Web Mercator Auxilliary Sphere.The images overlap each other by about 400 meters around their edges. The mosaic is configured by default so that the images with higher record numbers always cover images with lower record numbers, so that the appearance of the mosaic is static. Users of the mosaic may choose other mosaic methods that allow control over which image is displayed in areas where they cover each other.

Raster
Link to raster image
Name
Raster file name. For the doqq images, this string is built by concatenating the latitude and longitude of the southeast corner of the 1-degree block that contains the parent 7.5-minute quadrangle with the row and column number of the parent quadrangle (from the southeast) and the quarter quadrangle NE, NW, SE, or SW designation. Other images are reduced-resolution overviews of the data that are used for rapid display of the mosaic at small scales. The overview file names begin with the characters "Ov_".
MinPS
Minimum pixel size, used by ArcGIS to determine at which scale the image will be displayed
MaxPS
Maximum pixel size, used by ArcGIS to determine at which scale the image will be displayed
LowPS
Smallest pixel size contained in the raster
HighPS
Largest pixel size contained in the raster
Category
This is either 1 for Primary data sets or 2 for Overview images used for rapid display of the data at small scales.
Tag
This field is used by ArcGIS for mosaic functions not implemented for this data. The value is always "Dataset".
GroupName
This field is used by ArcGIS for mosaic functions not implemented for this data. The value is always an empty string.
ProductName
This field is used by ArcGIS for mosaic functions not implemented for this data. The value is always an empty string.
CenterX
Web Mercator x coordinate of the polygon centroid
CenterY
Web Mercator y coordinate of the polygon centroid
ZOrder
This field is used by ArcGIS for mosaic functions not implemented for this data. The value is always null.
Shape_Length
Length of the polygon perimeter in Web Mercator meters. Because of the scale distortion of the Web Mercator projection, this value, in Montana, is 40 to 50 percent larger than the actual perimeter.
Shape_Area
Area of the polygon in Web Mercator square meters. Because of the scale distortion of the Web Mercator projection, this value, in Montana, is 96 to 125 percent larger than the actual area.
Image_Year
This is the year during which the image was acquired.
Image_Main_Date
This is the date listed first by the U.S. Geological Survey in the list of dates of the photographs that were used to create the image. An image might contain data from several dates.
