bboxToVector: Convert and validate bbox objects or strings into standard...

In MazamaScience/MazamaSatelliteUtils: Utilities for Working with Model and Satellite Data as Rasters

Description

Accepts a variety of bbox formats, validates that they are numerically sane and returns a vector of floats in c(lonLo, lonLo, latLo, latHi) order. Input can be a vector of floats in c(lonLo, lonHi, latLo, latHi) order or the return value from sp::bbox() or raster::extent().

Usage

bboxToVector(bbox = NULL)

Arguments

bbox	Bounding box for the region of interest.

Value

a vector of floats in c(lonLo, lonHi, latLo, latHi) order.

Examples

library(MazamaSpatialUtils)
library(MazamaSatelliteUtils)

setSpatialDataDir("~/Data/Spatial")
setSatelliteDataDir("~/Data/Satellite")

loadSpatialData("USCensusStates")

oregon <- subset(USCensusStates, stateCode == "OR")
bbox <- sp::bbox(oregon)

scanFile <- goesaodc_downloadScanFiles(
  satID = "G16", 
  datetime = "2019-09-06 18:00", 
  timezone = "UTC"
)

scanRaster <- goesaodc_createScanRaster(
  filename = scanFile,
  cellSize = 0.1,
  dqfLevel = 2
)

extent <- raster::extent(scanRaster)
