targetLL {GEOmap} | R Documentation

## Target Lat-Lon

### Description

Get a target Lat-Lon from a set of Lat-Lon pairs

### Usage

    targetLL(sta, rdist = 100)

### Arguments

`sta` | station list (with slots lat lon)
`rdist` | radius in km

### Details

Uses the Median station as the center and returns the lat-lon extents of the target region.

### Value

list(

`A` | matrix with lat-lon pairs (lons=(0,360)
`B` | matrix with lat-lon pairs (lons=(-180, 180))
`mlat` | median latitude
`mlon` | median longitude
`Jlat` | range of lats
`Jlon` | range of lons
`proj` | projection list

### Examples

    sta=list( lat=rnorm(10, mean=60, sd=0.5),
    lon = rnorm(10, mean=60, sd=0.5))

    A = targetLL(sta, rdist = 100)
    print(A)

    sta=list( lat=rnorm(10, mean=-30, sd=0.5),
    lon = rnorm(10, mean=-40, sd=0.5))

    A = targetLL(sta, rdist = 100)
    print(A)
