Aero App users will receive an Invalid File message when attempting to load a dataset that is missing the corresponding SIG file. Missing SIG files will be highlighted on the Data Status page with a NO SIGNATURE message next to the dataset in question.
SIG files are unique to the corresponding dataset. Aero App uses the SIG file to verify the authenticity of the data file being loaded into the Active or Standby cycles.
Troubleshooting:
- Verify that the dataset being loaded contains both the data file and the SIG file with matching file names and cycle dates.
- Data may get lost, or become altered when transferred via external hard drives, or USB drives to personal devices. We recommend users download the required datasets from a different data source such as from Aero App Downloads.
Recommendations:
- Users can download data directly to Aero App by going to App Mgmt > Data > Download > AWS Fast Cloud Downloading > Sign in using GEOAxIS Disadvantage User or Aero User Database credentials.
- Users can have an Aero Data Server active and updated with the latest data cycle. Users can save their GEOAxIS Disadvantage User or Aero User Database credentials in the Auto Update section under Settings, allowing the data cycles to automatically update from AWS. Users will connect Aero App to the Aero Data Server and download data directly to the application.
