scan_to_spatial: convert a polar scan into a spatial object.

In adokter/birdRad: Biological Analysis and Visualization of Weather Radar Data

convert a polar scan into a spatial object.

Description

Georeferences the center of pixels for a scan into a SpatialPointsDataFrame object.

Usage

scan_to_spatial(scan, lat, lon, k = 4/3, re = 6378, rp = 6357)

Arguments

scan	a scan (sweep) of class scan
lat	Geodetic latitude of the radar in degrees. If missing taken from scan.
lon	Geodetic longitude of the radar in degrees. If missing taken from scan.
k	Numeric. Standard refraction coefficient.
re	Numeric. Earth equatorial radius, in km.
rp	Numeric. Earth polar radius, in km.

Details

Beam altitude accounts for the curvature of the earth, using beam_height. Distance from the radar over the earth's surface is calculated using beam_distance.

Value

a SpatialPointsDataFrame

Examples

# load example scan:
data(example_scan)

# convert to a SpatialPointsDataFrame:
scan_to_spatial(example_scan)
