MnGAC Archiving Imagery Workgroup survey
The MNGAC Archiving Imagery Workgroup is currently investigating best practices for archiving aerial imagery data. Part of this work is to gather an inventory of the types of imagery resources available across the state that would be suitable for archiving.

For our purposes, we are considering digitized aerial photography only at this point. This may be imagery that is scanned photos, georeferenced / georectified image files, or image services. Examples of file formats are TIFF, JPEG, SID, GRID, and their associated spatial info files. We are also interested in index files. We are not collecting information about satellite imagery or LiDAR files at this point.

We are only considering digitized aerial photography at this point. Examples of file formats are TIFF, JPEG, SID, or GRID. This includes:

  • scanned photos
  • georeferenced / georectified image files
  • image services
  • associated spatial information files and index maps

This survey is NOT collecting information about:

  • satellite imagery
  • LiDAR

If your organization has aerial imagery that you would like us to consider for archiving, please fill out the following fields. Please complete the survey multiple times if you have multiple sets of aerial imagery for us to consider. All of the fields are optional.
