Georeferencing – Should I Update or Rectify?

Once you have finished choosing and evaluating your links, you are ready to persist your results. There are 2 options to choose from: Update Georeferencing and Rectify.

Update Georeferencing

• Only updates your files- no redundancy created
• Update are almost immediate

Rectify

• A new raster dataset is created and the original file is left unaltered
• Choose many options: such as file format, cell size, resampling technique, and NoData value.
• This is the only option for some files: such as GRID and other files that cannot be updated (e.g. read-only files)

Depending on your workflow, both Update Georeferencing and Rectify have their advantages.
