NAD 1983 NTM zone 10N(west of 120°) or zone 11N(east of 120°) | The photos come in two formats, uncompressed images in USGS DOQQ and compressed images using JPEG compression algorithm. Compressed images are smaller in size while the uncompressed images have the best quality. There is no much difference if they are to be looked by human eyes. But if they are to be machine-analyzed, please request uncompressed images because the errors introduced by compression / uncompression might be a problem for you. |
| Pieces of both compressed and uncompressed imagery can be clipped at the Washington State OrthoImagery Portal (approximately 8 minutes to download 200MB, which is about the size of one USGS DOQQ image tile) | |||||
