If you prefer to have the decimal degrees instead, simply add the -n flag exiftool -r -n -all -csv *.tif > metadata. In order to export all the data in a spreadsheet, you can use the following command: exiftool -r -all -csv *.tif > metadata.csvīy default, Exiftool converts some values into more human-readable format such as You can check against the group All:All but processing will be very slow as it will check against all tags that exiftool knows, not just what is in the file, which numbers in the 10s of thousands. In cases where a tag name exists in more than one namespace, less common namespaces are avoided when writing. With that command, if one of the tags in the EXIF group contains a value that includes 'Unknown', then all the EXIF tags will be displayed. This includes namespaces which are not pre-defined by ExifTool. Or if you want to instead see some GPS information exiftool IMG_0000_1.tif | grep -i gps The tags of any namespace may be deleted as a group by specifying the family 1 group name (eg. exiftool IMG_0000_1.tif | grep -i irradiance Here we use the -i flag to make our search term case-insensitive. Let's say I want to see all Irradiance data from a DLS2. Sometimes, you want to see only a specific tag. If you want to see the data for all bands of a particular capture, you can use a wildcard as follows: exiftool IMG_0000_*.tif This will return all the metadata tag names and its associated values for the specified image. Viewing all metadata of a particular image exiftool IMG_0000_1.tif These commands work on Mac and Linux terminals alike. These examples assume you have navigated to the directory containing your raw images from your MicaSense camera. Below are some examples of common usages and expected outputs. Once installed in your operating system of choice, you will have the ability to use the command line to quickly view and export your desired metadata. There are many solutions out there, but we prefer one called ExifTool by Phil Harvey. In order to view and extract this information, you will need special software that allows you to view and edit EXIF data in your images. All strings occurring as values will be Unicode strings. All keys are Unicode strings with the tag names, including the ExifTool group name in the format :.Note that this is not a necessary step in processing your images in photogrammetry software such as Pix4Dmapper or Agisoft Metashape but is a useful option for being able to view the information stored in your images for analysis. The return value is a list of dictionaries, mapping tag names to the corresponding values. In some instances, more than one name may correspond to a single tag ID. A Tag Name is the handle by which the information is accessed in ExifTool. An Index refers to the location of a value when found at a fixed position within a data block, and Sequence gives the order of values for a serial data stream. MicaSense raw images have a wealth of useful information including imager information, irradiance measurements, GPS coordinates, and more. A Tag ID is the computer-readable equivalent of a tag name, and is the identifier that is actually stored in the file.
