Constructor & Destructor Documentation

rainGrid::rainGrid ( std::vector< std::vector< float > > &  rain_data, TNT::Array2D< int > &  hydroindex, int  imax, int  jmax, int  current_rainfall_timestep, int  rf_num  )

inline

Create a raingrid from the rainfall data vector, and the raster or model domain dimensions, for the current timestep only. Specify an interpolation method

Member Function Documentation

void rainGrid::downscaleRainfallData

(

)

Downscales the 2d rainfall array to a resampled, higher resolution array, with the same grid spacing, and dimensions as the model or raste rdomain.

Note

This is actually done by the create() function for now, but it should probably go in its own method.

void rainGrid::interpolateRainfall_RectBivariateSpline

(

rainGrid &

raingrid

)

Create rainGrid from interpolating between sparse points and x, y coord TODO Takes a 2D array of regular gridded rainfall and interpolates it according to a Bivariate Spline. Similar to sciPy's scipy.interpolate.RectBivariateSpline

void rainGrid::interpolateRainfall_RectTrivariateSpline	(	rainGrid &	raingrid,
		const TNT::Array2D< double > &	elevation
	)

Will take a 2D array of regular gridded rainfall and interpolates it based on a TRI-variate spline. I.e. interpolates based on an extra third variable which would be terrain in most cases (see Tait et al 2006, for example)

void rainGrid::ReShapeRainfallData_2DArray

(

)

Takes the rainfall data for a current timestep and reshapes it into a 2D array.

void rainGrid::write_rainGrid_to_raster_file	(	double	xmin,
		double	ymin,
		double	cellsize,
		std::string	RAINGRID_FNAME,
		std::string	RAINGRID_EXTENSION
	)

Writes the 2D upscaled and/or interpolated rainfall grid to a raster output file for checking.

Member Data Documentation

TNT::Array2D<double> rainGrid::rainfallgrid2D

protected

For a single instance of a 2D rainfall grid, matching the dimensions of the model domain.

TNT::Array3D<double> rainGrid::rainfallgrid3D

protected

Experimental - stores grids of rainfall data for every rainfall timestep: Warning - this could be a massive object!
