Pacific Palisades

Figure 1: A minimalist map of Pacific Palisades, California, featuring its detailed street network and building footprints, with the Pacific Ocean labeled prominently at the bottom. The design uses a clean blue-and-beige color scheme for clarity and elegance.

How This Graphic Was Made

1. 📦 Load Packages & Setup

# Load necessary packages using pacman for easier dependency management
pacman::p_load(
  sf,          # For handling shapefiles and geospatial data
  osmdata,     # For fetching OpenStreetMap data
  showtext,    # For adding custom Google fonts
  ggtext,      # For enhanced text formatting in plots
  tidyverse,   # For data manipulation and visualization
  sysfonts,     # For working with system fonts
  glue
)

# Add Google Font
# Add the Posterama 1927 font using its full path
font_add(family = "Posterama", regular = "C:/Users/gonza/AppData/Local/Microsoft/Windows/Fonts/Posterama 1927.ttf")
font_add_google("Roboto Condensed")

# Add local font
font_add("Font Awesome 6 Brands", here::here("fonts/otfs/Font Awesome 6 Brands-Regular-400.otf"))

# Enable custom fonts
showtext_auto()
showtext_opts(dpi = 300)

2. 📖 Load Building Footprints

# Load the building footprints from a GeoPackage file
palisades_path <- here::here("Data/Palisades_buildings.gpkg")
buildings <- st_read(palisades_path)

3. 🕵 Filter and Transform PALISADES Data

# Filter for buildings in the PALISADES ZIP Code
palisades <- buildings %>%
  filter(str_detect(SitusZIP, '90272'))

# Reproject PALISADES data to WGS84 (EPSG:4326)
buildings <- st_transform(palisades, crs = 4326)

4. 🤼 Define the Los Angeles Bounding Box

# Define the geographic extent of Los Angeles for the plot
la_bbox <- st_bbox(c(xmin = -118.56, ymin = 34.03, xmax = -118.50, ymax = 34.06), crs = 4326)
la_bb <- st_as_sfc(la_bbox)

5. 🔤 Text

title <- "PACIFIC PALISADES"

subtitle <- "CALIFORNIA, USA"

# Create a social media caption with customized colors and font for consistency in visualization
social <- andresutils::social_caption(font_family = "Roboto Condensed", icon_color = "#1A3D91", font_color = "grey45") 

# Construct the final plot caption by combining TidyTuesday details, data source, and the social caption
cap <- paste0(
  "**Source**: OpenStreetMap | **Graphic**: ", social
)

6. 🗺️ Download OpenStreetMap Data

# Fetch major streets
la_big <- la_bb %>%
  opq() %>%
  add_osm_feature(key = "highway",
                  value = c("motorway", "primary", "secondary", "tertiary", "trunk")) %>%
  osmdata_sf()

# Fetch street connectors (links)
la_links <- la_bb %>%
  opq() %>%
  add_osm_feature(key = "highway",
                  value = c("motorway_link", "primary_link", "secondary_link", 
                            "tertiary_link", "trunk_link")) %>%
  osmdata_sf()

# Fetch minor streets
la_small <- la_bb %>%
  opq() %>%
  add_osm_feature(key = "highway",
                  value = c("residential", "road", "footway")) %>%
  osmdata_sf()

7. 📊 Plot

  coord_sf(xlim = c(-118.56, -118.50), ylim = c(34.03, 34.06)) +

  ) +
  labs(
    title = title,
    subtitle = subtitle,
    caption = cap
  )
