addCropArea: addCropArea

In sidjai/biosplit: Model for continental seasonal migration of insects

Description

This function is for adding an additional crop area that was not included in the NASS system. The most obvious use case is for areas just outside of U.S, like in the Ontario province in Canada. Another is for transcontinental migration adding large splotches of Mexico, Carribean and Canada. The function works by looking at a shape file for a grid of points (lat, lon) and using the cropAmt to create an additional area to add to the original file.

Usage

addCropArea(pathIn, shapeAdd, cropAmt, pathOut = "")

Arguments

pathIn	The path of the parsed and projected crop nc file
shapeAdd	Either A shape file from Google Earth (kml) defining the area, or an x,y matrix defining the added points.
cropAmt	The amount of crop in that area which is either constant or the length of the input shape file
pathOut	The path out of the final nc file

Value

The final raster and the new nc file if pathOut is specified.
