| Descriptive name | BLM Arizona Imagery Mosaic | |
| File name | opdoq96b | |
| Spatial domain | Arizona | |
| Abstract | This is a monochrome 1990-1999 Arizona imagery mosaic from various sources and image types. This imagery is a composite believed to have been made by the BLM. The mosiac's images were taken from various sources including the USGS and from various special projects. Some USGS color infrared imagery was adapted by using only the green band to produce the monochrome image. The mosaic includes over 8,000 DOQQ images. Each source image has between 50 and 300 meters of overedge image beyond the latitude and longitude corner crosses embedded in the image. The overedge has been clipped off and the images have been georeferenced to align with each other in a seamless mosaic grid. Due to variations in the individual photos, the seams are often visible. See more information. | |
| Known errors/qualifications | While this layer is a useful state-wide image and represents the best that was available to make a state-wide image at the time it was assembled, one professional's opinion with knowledge of the project calls it "awful stuff", presumably because of the compositing of various types of images and the method used to convert some imagery to monochrome. | |
