# Fathom data

[Fathom](https://www.fathom.global/) provide flood hazard maps with global coverage. These maps can be retrieved and viewed directly in the Map view by linking your Fathom account to Flood Modeller in the [Application Settings](/v1/docs/application-settings).

Don't have a Fathom account?If you do not have a Fathom account, fill in the following form and the Fathom team will get in touch: [https://www.fathom.global/fathom-jacobs-licence/](https://www.fathom.global/fathom-jacobs-licence/)

The map tile retrieved is based on extent of map window when you open the tool.
