[postgis-users] Old question resurfacing

[Gerry Creager - NOAA Affiliate]

At least preliminarily, I can post-process, so speed of db adds isn't too
troubling. Maintaining accurate representation of the bin-volume data is,
however, important.

Typical rotation is 1-3 RPM, and a complete volume scan takes ~11 min in
clear air (where you best see biologicals if so inclined) or ~5 min in one
of the storm data collection modes. These are for common WSR88D, stationary
radars. SMARTR's and others we have here that are mobile present a whole
host of other options/data eval and speed problems.

Current radar data are nominally considered to have a horizontal resolution
of ~250 m, ignoring distortion or keyholing due to range.Typically 16
elevations are scanned, once or or twice in storm mode and a few less
elevations in clear air mode.

Now, the interesting thing that's on the horizon is Phased Array Radar.
When that happens, more data, more resolution, and faster updates.

That feed on their velocity;
And little whorls have lesser whorls,
And so on to viscosity.”
