This will discuss the point cloud to DEM accuracy specifications

@andycarter-pe So is the approach we used for Balmorhea the same as the ASPRS?

[dhardestylewis]

@andycarter-pe is our figure same as ANPS for this dataset?

[dhardestylewis]

• [ ] this is ANPS, so change terrain_aggregator DB of Balmorhea's LPC resolution from .7m to .35m

Based on this spec, was it accurate to set the "Lidar resolution" to 70cm?
