Wait, are we sure the insurance company can even read the Lidar data? Better stick with something more user-friendly, like the USGS 30-meter DEM.

Good point, the insurance company might not be able to work with Lidar data. USGS 30-meter DEM is a safer choice.

I'm torn between the Lidar and the 30-meter stereo imagery. Both could work, but I think the Lidar might give us the edge in terms of accuracy.

The Lidar 5-meter DEM is definitely the way to go for precise flood zone mapping.

Haha, the SRTM 90-meter DEM? That's like trying to map a river with a basketball court! Definitely not the way to go here.

That sounds like a good choice too, it should give us the detail we need for the flood zone map.

Lidar 5-meter DEM for sure! The higher resolution will give much more detailed and accurate flood zones.
