Metadata are the additional data added to multimedia files. It's a open source program for reading, modifying, and manipulating images, videos, audios and PDF metadata. If you prefer to have the decimal degrees instead, simply add the -n flag exiftool -r -n -all -csv *.tif > metadata.You may have come across ExifTool while searching for an image recovery software. 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 Or if you want to instead see some GPS information exiftool IMG_0000_1.tif | grep -i gps 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. 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. MicaSense raw images have a wealth of useful information including imager information, irradiance measurements, GPS coordinates, and more.
