Shared Overlays (GeoPDFs)

Overview

Shared Overlays or GeoPDF overlays is a world-leading capability within FireMapper that allows you to overlay georeferenced PDFs on top of the map:

These overlays are visible to any user of the Portal Map or in FireMapper Enterprise.

To get started, simply drag and drop a georeferenced PDF into the portal map. If the file is a valid GeoPDF you will see a preview overlay on the map:

../_images/preview.png

Click ‘Start Upload’ and wait until you see “Processing file. You may now close this tab.”. The overlay will take a few minutes to process and you will be alerted via email when it’s ready. To view the overlay, navigate to the “Layers” tab, scroll down to “Shared Overlays” and click the overlay you wish to view.

You can toggle the overlay on and off by clicking the panel. You can also adjust the opacity of the overlay with the slider control (after clicking the spanner icon).

Should you have any issues uploading the GeoPDF, you can contact support@firemapper.app. If you are able to share the GeoPDF file with us, our technical team will help to upload it for you.

GeoTIFF Support

Similar to GeoPDF overlays, you can overlay multiple GeoTIFF files onto Shared Maps in the Portal. These can also be toggled on and off, or deleted via the Portal.

To import a GeoTIFF file onto your map, you can select Edit, followed by the Add File button. Once the file upload has been completed, your GeoTIFF file will be visible as an overlay.

Please note that the file size cannot exceed 1GB.

Notes

  • Multiple overlays can be shown at once.

  • Overlays are not included in Print Previews, or other Exports

  • Overlays are map specific - you will need to upload the PDF to each map that you would like to display it on

  • GeoPDFs may not exceed 20Mb

  • There is a 5 minute processing time-limit for GeoPDFs - you could trigger this if you upload a large area at a high zoom-level

  • The initial preview might look different to the final product - please continue with the upload regardless of the preview
