interpolateByArea: interpolate a variable from one set of shapes to another

In terminological/arear: Geospatial Convenience Functions and a Supply Demand Catchment Area Generator

interpolate a variable from one set of shapes to another

Description

interpolate a variable from one set of shapes to another

Usage

interpolateByArea(
  inputDf,
  inputShape,
  by,
  interpolateVar,
  outputShape,
  inputVars = inputDf %>% dplyr::groups(),
  outputVars = outputShape %>% dplyr::groups(),
  aggregateFn = sum
)

Arguments

inputDf	- in input data frame containing the variable(s) of interest to interpolate. Stratification of the variable can be achieved by grouping
inputShape	- an input sf map,
by	- the columns to use to join the inputDf to the map provided in inputShape. This is in the format of a dplyr join specification.
interpolateVar	- the column that we want to do areal interpolation on,
outputShape	- an output map which may be grouped by the desired output,
inputVars	- a list of columns from the inputDf (as a dplyr::vars(...) list) that define the stratification of inputDf and are desired in the output. Defaults to the grouping of inputDf
outputVars	- a list of columns from the outputShape (as a dplyr::vars(...) list) that we want preserved in output, or defined as a grouping of outputShape
aggregateFn	- a function that will be applied to area weighted components of interpolateVar - defaults to sum

Value

a dataframe containing the grouping columns, the outputIdVar and the interpolated value of interpolateVar
