I thought USGS 30-meter was decent too, but Lidar seems better.

I'm not entirely sure, but I remember something about stereo imagery being useful too. Maybe the 30-meter DEM from stereo imagery could work?

I think the Lidar 5-meter DEM would provide the most accurate flood zones since it has the highest resolution.

The Lidar DEM is definitely the most accurate option, but it might be overkill for this use case. The 30-meter USGS data could be a good balance of quality and practicality. I'll have to consider the project requirements and budget constraints.

Hmm, this is a tough call. I'm leaning towards the Lidar data since it has the highest resolution, but the SRTM 90-meter DEM could be a good compromise between accuracy and coverage. I'll need to weigh the tradeoffs.

I'm a bit unsure about this one. The Lidar data sounds great, but the 30-meter USGS DEM might be a safer bet since it's a more established dataset. I'll have to think this through carefully.

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.
