#258 | fixed | TIFF tagger | chrfi | mggr |
Description |
We need a small tool for adding tags (small text/numerical elements) to TIFF image files. The pre 2009 aerial photos contain metadata inserted by a scanning company. You can see what's in the 2008 photos by doing something like tiffinfo ~arsf/arsf_data/2008/flight_data/uk/GB08_18-2008_176a_River_Frome/photography/08_03_8190.tif | less. Mostly they seem to have created an XML metadata section. Many of their tags relate to the scanning process and are not relevant. Ideally we should duplicate the XML metadata in addition to putting data into relevant tags. There are a large number of defined tags and a mechanism for picking "free" tags. I'd suggest trying to conform to the EXIF standard where possible. http://www.awaresystems.be/imaging/tiff/tifftags.html
For example, there are predefined tags for GPS location that we may wish to use as that'd mean the images could be correctly geolocated in a standard package. There are also some bits for descriptions and comments, which could be used for the project info.. Alternatively, you could pick one of the "free" ranges and make up your own tag. Before making up your own tag, please a) check for a standard one and b) check what the 2008 photos did. Suggested approach:
