Description

Extract radar Cartesian data over a set of points.

Usage

extractRadarGrid(
  url,
  source,
  start_time,
  end_time,
  fields,
  points,
  levels = -1,
  padxyz = c(0, 0, 0),
  fun_sp = "mean",
  time_zone = "Africa/Kigali"
)

Arguments

url	The URL of the server. Ex: "http://192.168.1.10:8080"
source	A partial path of the directory containing the folders dates of the mdv files. Ex: "radarCart/ops", "ctrec" or "radarCart/echo_tops"

fields	Vector of the fields to extract.
points	A data frame of the points to extract. Data frame with column names "id", "longitude" and "latitude"
levels	A vector of the index of altitudes to be extracted in integer, or -1 to extract all available altitude
padxyz	A vector of the padding to use in number of pixels, in order "lon", "lat", "alt"
fun_sp	Character, function to be used for the padding. Options: "mean", "median", "max", "min"
time_zone	the time zone of start_time, end_time and the output QPE. Options: "Africa/Kigali" or "UTC". Default "Africa/Kigali"

Value

A named list

• points: the original points used to extract the data

• date: list of dates of the extracted data

• altitude: list of the altitudes of the extracted data

• data: list of the fields in the form of 3d array.
  Dimension: (length(date) x length(altitude) x length(points))
