In RgoogleMaps: Overlays on Static Maps

plots on map tiles by "stitching" them together

Description

Counterpart to PlotOnStaticMap for map tiles

Usage

PlotOnMapTiles(mt, lat, lon, center, size = c(768, 


    768), add = FALSE, FUN = points, mar = c(0, 0, 


    0, 0), verbose = 0, ...)

Arguments

mt	list returned by GetMapTiles
lat	latitude values to be overlaid, if any
lon	longitude values to be overlaid, if any
center	optional center
size	size (in pixels) of "stitched" map
add	start a new plot or add to an existing
FUN	plotting function to use for overlay; typical choices would be points and lines

  lon = c(-74.012318,-74.015794,-73.998284);


  center = c(mean(lat), mean(lon));


  zoom <- min(MaxZoom(range(lat), range(lon)));


  bb=qbbox(lat,lon)


  


  manhattan_osm = GetMapTiles(latR =bb$latR , lonR=bb$lonR,zoom=zoom,verbose=1)


  PlotOnMapTiles(manhattan_osm,lat=lat,lon=lon,pch=20,col=c('red', 'blue', 'green'),cex=2)


  


  manhattan_goo = GetMapTiles(latR =bb$latR , lonR=bb$lonR,zoom=zoom,


                   tileDir= TRUE, type="google" )


  PlotOnMapTiles(manhattan_goo,lat=lat,lon=lon,pch=20,col=c('red', 'blue', 'green'),cex=2)
