Every layer on GEO can be downloaded and used outside the platform — in your own modelling tools, GIS software, or spreadsheets. Downloads are available from the Downloads section of any event report.

All MIS-published layers are available for download, including:

Pre-Event Exposure outlook downloads work a little differently — they're portfolio-matched exports rather than raw map layers, and live in the Outlook Downloads panel on the Summary tab rather than this Downloads section. See [Pre-Event Layers & Outlook].

Imagery cannot be downloaded. If you need imagery for a specific use, contact [email protected].

Each layer is available in three formats:

Choose the format that works with the tool you're loading the data into. If you're unsure, shapefile is the most widely supported format for GIS tools.

The file downloads to your computer immediately.

Every downloaded layer includes a created at date — the timestamp of when MIS last updated that layer. When you load the file into another platform or share it with a colleague, the created at date tells you exactly which version of the data you're working with.

This matters for large events where the Claims Layer is updated multiple times. A Claims download from day three will reflect different data than one from day ten. Always check the created at date before running analysis on a downloaded file.

Downloaded layers are commonly used to:

If you're loading a shapefile into external software and find the file is too complex or slow to render, see [Reducing Layer File Size with Mapshaper] for guidance on simplifying the geometry.

Why can't I download imagery?
Imagery is licensed from third-party providers under terms that don't permit redistribution. If you need imagery for a specific investigation or legal purpose, contact [email protected].

I need a layer from an older date — can I get a historic version?
GEO provides the current published version of each layer. If you need a specific historic version of a layer (for example, the Claims Layer as it appeared on a specific date), contact [email protected]. Alternatively the API has access to all historical assessment layers.

The shapefile won't load in my GIS platform. What should I do?
For complex events with large footprints, shapefiles can be too detailed for some platforms to handle. Use the Mapshaper tool to reduce the file size — see [Reducing Layer File Size with Mapshaper].

Can I download layers for historic events?
Yes. The Downloads section is available on all event reports, including historic events in the archive.

Where do I download Pre-Event Exposure data for a developing storm?
That's in the Outlook Downloads panel on the Summary tab, not this Downloads section. See [Pre-Event Layers & Outlook].
