Below is all the information we have available on file about the .coo (coo) file type.
.coo files are generated and used by AutoCAD, and are also known as cookie files where each cookie file will relate to a single raster file.
A .coo file is a text editable file, and contains the bounding coordinates for a geocoded image/raster file in Cartesian space (for use when for example loading into a mapping system.)
A coo file contains 9 lines, such as:
File name: 5154.tif File type: TIFF B&W PACKBITS LLX: 96000 LLY: 133000 URX: 100000 URY: 136000 Resolution 0.2 Columns 20000 Lines 15000
Each line provides the following information:
| Line 1: | File name | The name of the image/raster file. In the example above the image file is a .tif file but it could be other types of image file or a .dwg file. |
| Line 2: | File type | |
| Line 3: | LLX | X-Coordinate (or Easting) of the pixel at the lower left corner. |
| Line 4: | LLY | Y-Coordinate (or Northing) of the pixel at the lower left corner. |
| Line 5: | URX | X-Coordinate (or Easting) of the pixel at the upper right corner. |
| Line 6: | URY | Y-Coordinate (or Northing) of the pixel at the upper right corner. |
| Line 7: | Resolution | Scale, indicating the effective height/width of each pixel in physical units. In the example above, each pixel corresponds to an area of 0.2m2 |
| Line 8: | Columns | The width of the image in pixels. |
| Line 9: | Lines | The height of the image in pixels. |
Where this is available we would like to include file format information on .coo files, as well as information on how to view or open files of type .coo. If you know of any information which we have missed then please let us know.
