In MazamaSpatialUtils: Spatial Data Download and Utility Functions

Summarize values by polygon

Description

Given vectors of longitudes, latitudes and values, this function will summarize given values by spatial polygon using the FUN and return a dataframe with polygon IDs and summary values.

Usage

summarizeByPolygon(
  longitude,
  latitude,
  value,
  SFDF,
  useBuffering = FALSE,
  FUN,
  varName = "summaryValue"
)

Arguments

longitude	vector of longitudes
latitude	vector of latitudes
value	vector of values at the locations of interest
SFDF	simple features data frame with polygons used for aggregating
useBuffering	passed to MazamaSpatialUtils::getSpatialData()
FUN	function to be applied while summarizing (e.g. mean, max, etc.)
varName	variable name assigned to the summary variable

Value

A dataframe with the same rows as 'SFDF' but containing only two columns: 'polygonID' and the summary value.
