FarmData | R Documentation |
This list object contains four matrices covering adjusted yield, wind speed, wind direction and standard deviations of wind directions in Germany.
FarmData
A list
object containing seven matrices, each containing 25 x 25 values at a raster resolution of 200 x 200 m (note that for the larger data set downloadable using AcquireData
, each matrix contains 4400 x 3250 values):
$AdjustedYield
: Yield is average annual energy production (AEP). According to FGW technical guidelines, AEP is adjusted due to different location qualities to obtain a better guess at the marketable energy output. Interpret these values directly as 'megawatt hours per year'.
$WindSpeed
: Average wind speeds in meters per second.
$WindDirection
: Average wind directions in degrees (azimuth system).
$SDDirection
: Standard deviations of wind directions in degrees (azimuth system).
$Elevation
: Terrain relief (elevation in meters).
$Slope
: Terrain slope in degrees.
$SlopeDirection
: Direction of hillside in degrees.
If the full mode data set is present, it is loaded into the environment e
. The built-in data set FarmData
contains matrices of dimension 25 x 25, while the full data set e$FarmData
consists of 4400 x 3250 matrices.
