One important component in this process was the use of the Google Map Maker data to clearly map the transport networks, allowing emergency managers to plan and implement relief assistance. For example, they could avoid roads that are marked on the maps as likely to be flooded by comparing satellite flood layers with road layers.

We've been pleased to hear positive feedback directly about this combination of imagery with Map Maker data directly from those in the field -- as one simply stated, "Thumbs up!"
