When running the code a bunch of magick-Tiff warnings are given: "unknown field with tag ***** encountered - These all seem to be related to the georeferencing, so they might not result in any issues, but just be magick not knowning what to do with geospacial information
magick: Unknown field with tag 33550 (0x830e):
Used in interchangeable GeoTIFF files.
This tag is optionally provided for defining exact affine transformations between raster and model space. Baseline GeoTIFF files may use this tag or ModelTransformationTag, but shall never use both within the same TIFF image directory.
This tag may be used to specify the size of raster pixel spacing in the model space units, when the raster space can be embedded in the model space coordinate system without rotation, and consists of the following 3 values:
ModelPixelScaleTag = (ScaleX, ScaleY, ScaleZ)
where ScaleX and ScaleY give the horizontal and vertical spacing of raster pixels. The ScaleZ is primarily used to map the pixel value of a digital elevation model into the correct Z-scale, and so for most other purposes this value should be zero (since most model spaces are 2-D, with Z=0).
magick: Unknown field with tag 33922 (0x8482)
Originally part of Intergraph's GeoTIFF tags, but now used in interchangeable GeoTIFF files.
This tag is also known as 'GeoreferenceTag'.
This tag stores raster->model tiepoint pairs in the order
ModelTiepointTag = (...,I,J,K, X,Y,Z...)
where (I,J,K) is the point at location (I,J) in raster space with pixel-value K, and (X,Y,Z) is a vector in model space. In most cases the model space is only two-dimensional, in which case both K and Z should be set to zero; this third dimension is provided in anticipation of future support for 3D digital elevation models and vertical coordinate systems.
magick: Unknown field with tag 34735 (0x87af):
Used in interchangeable GeoTIFF files.
This tag is also know as 'ProjectionInfoTag' and 'CoordSystemInfoTag'
This tag may be used to store the GeoKey Directory, which defines and references the "GeoKeys".
magick: Unknown field with tag 34736 (0x87b0)
Used in interchangeable GeoTIFF files.
This tag is used to store all of the DOUBLE valued GeoKeys, referenced by the GeoKeyDirectoryTag. The meaning of any value of this double array is determined from the GeoKeyDirectoryTag reference pointing to it. FLOAT values should first be converted to DOUBLE and stored here.
magick: Unknown field with tag 34737 (0x87b1)
Used in interchangeable GeoTIFF files.
This tag is used to store all of the ASCII valued GeoKeys, referenced by the GeoKeyDirectoryTag. Since keys use offsets into tags, any special comments may be placed at the beginning of this tag. For the most part, the only keys that are ASCII valued are "Citation" keys, giving documentation and references for obscure projections, datums, etc.
