pix.id.find: Match Longitude and Latitude of clusters to pixel IDs in grid

In obrady/SpatialDengue: Fits and simulates a spatial model of the vector-borne disease dengue

Description

This function takes latitude and longitude of identified cases and matched them to a specific identifier from the unipix dataframe

Usage

pix.id.find(longlat, unipix)

Arguments

longlat	A two element vector of Longitude followed by Latitude
unipix	A universal lookup table detailing all pixels within the grid. Must contain a pixel ID in the first column and the fields "x" (Longitude) and "y" (Latitude)

Details

uses pixel stepwise distance (Longitude + Latitude) to identify nearest pixel to the given LatLong.

Examples

data(sgdat)
data(sgpop)
unipix <- make.unipix(sgpop)
pix.id.find(c(sgdat$Longitude[1], sgdat$Latitude[1]), unipix)
