Description

Gets the information about all the satellites known in the Spectator Earth database, and possibly their current positions.

Usage

GetAllSatellites(positions = TRUE)

Arguments

positions

logical indicating if the current position should be included. Default: TRUE

Value

If positions is FALSE, a data frame with following attributes:

id

integer identifier

name

character satellite name

norad_id

integer satellite catalog number

open

logical whether the data produced by the satellite is freely accessible

platform

character platform name

sensor_name

character name of the sensor available on the satellite

sensor_swath

integer swath width of the sensor available on the satellite

sensor_type

character type of the sensor available on the satellite (SAR or Optical)

If positions is TRUE, object of class 'sf' with 'POINT' geometry type, with the same attributes as above.

Examples

if(interactive()){
 library(sf)
 # get all satellites withe their positions
 pos <- GetAllSatellites(positions = TRUE)
 # do some nice graphs
 library(maps)
 map("world", fill = TRUE, col = "lightgrey")
 # show open data satellites in green
 plot(st_geometry(subset(pos, open == TRUE)), add = TRUE, col = "green", pch = 15)
 # show others in red
 plot(st_geometry(subset(pos, open == FALSE)), add = TRUE, col = "red", pch = 16)
 # add labels
 xy <- st_coordinates(pos)
 # shift labels up to be able to read them
 xy[, 2] <- xy[, 2] + 2 
 text(xy, labels = pos$name, cex = 0.5)
