r-spatial
All background maps are blank.
When plotting data on mapview in R, the data points show up, but the background maps do not. I am behind a firewall so I have to use a proxy to get the data. Do I have to set up something similar to be able to load the background maps?
I'm suspecting that the loading of the maps are being stopped by the firewall.
So I end up with a bunch of dots on a blank background.
I'm having the same issue here with both sf and sp object types. However, I can load a map using breweries just fine. So, likely something with how I'm formatting my data...
Example data and code:
#Load packages
library(tidyverse)
library(sf)
#Create example data
latitude = c(44.10606, 44.10668, 43.69781, 43.58378, 43.83922, 43.84134)
longitude = c(-124.0897, -124.0890, -122.0458, -122.7138, -122.5581, -122.5467)
#Make spatial dataframe
data = data.frame(latitude, longitude) %>%
st_as_sf(coords = c('longitude', 'latitude'))
#Generate map (without basemap)
mapview(data)
I am using R v. 4.2.2 in RStudio v. 2022.2.04 on Mac OSX v. 10.15.7. I'm using mapview v. 2.11.0, sf v. 1.0-9, sp v. 1.6-0.
I have found that this just happens within the Rstudio viewer pane and again on a corporate network so it could be something blocking the Viewwer pane from calling urls. A workaround is to click the icon to view the map in a new window which opns it in a browser. from memory the Rstudio Viewer is a type of browser (within a web app which is what Rstudio is)
I found that mapview has a problem loading the background map when the sf points do not have a CRS.
library(sf)
library(mapview)
library(tidyverse)
data(breweries)
mapview(breweries)
# Works fine, plots points with OSM background map
points <- data.frame(pt.names = letters[1:3],
lats = c(34, 35, 36),
longs = c(-110, -111, -112))
points %>%
st_as_sf(coords = c("longs", "lats")) %>%
mapview()
# plots points without background map
points %>%
st_as_sf(coords = c("longs", "lats")) %>%
mapview(crs = 4381)
# Also plots points without background map
points %>%
st_as_sf(coords = c("longs", "lats"),
crs = 4381) %>%
mapview()
# Plots points with background map
So maybe the problem is with the CRS substitution?
