scaleShape: Scales shapefile.

In madorning/energySimMD: Spatial Energy Simulation: Linking Subsurface to Surface Resources

Description

Scales input shapefile to desired area assuming stationary centroid. Units must be the same.

Usage

scaleShape(inShape, newArea)

Arguments

inShape	A shapefile
newArea	A number for the desired area

Details

For more complex shape scaling and transformations, see scaleShapeTransformation

Value
