goesaodc_createSpatialPoints.Rd
Create a SpatialPointsDataFrame of GOES data including data within the specified bounding box and data quality flag level.
The dqfLevel
parameter can take a value of:
0 -- High quality retrieval flag
1 -- Medium quality retrieval flag
2 -- Low quality retrieval flag
3 -- No retrieval quality flag
The bbox
parameter can be a vector of floats in c(lonLo, lonHi, latLo,
latHi) order or the return value from sp::bbox()
or
raster::extent()
.
goesaodc_createSpatialPoints( nc = NULL, bbox = c(-125, -65, 24, 50), dqfLevel = NULL )
nc | ncdf4 handle. |
---|---|
bbox | Bounding box for the region of interest. |
dqfLevel | Data quality flag level. |
