Final Dashboard - Selected City Map phx_dorling.geojson

[AhmedRashwanASU]

Is the Below JSON file is only for Phoenix Map? If YES then where can I get my Selected City Map URL?

github.url <- "https://github.com/DS4PS/cpp-529-fall-2020/raw/main/data/phx_dorling.geojson"

phx <- geojson_read( x=github.url,  what="sp" )

# reproject the map 
phx2 <- spTransform( phx, CRS("+init=epsg:3395") )

# convert the sp map format to 
# an sf (simple features) format:
# ggmap requires the sf format
phx.sf <- st_as_sf( phx2 )

# separate out the data frame from the map
d <- as.data.frame( phx.sf )

Hi Ahmed,

You can create the dorling map for you city based on the work we did in Lab

4. Please find the Lab 4 solutions to check out (link https://www.dropbox.com/s/lblrpwrigea8ljh/lab-04-solutions.rmd?dl=1). You need to read in the census data and spatial features, and then transform the shapefile into the dorling.

Let me know if that helps.

Best,

reproject the map

phx2 <- spTransform( phx, CRS("+init=epsg:3395") )

convert the sp map format to

an sf (simple features) format:

ggmap requires the sf format

phx.sf <- st_as_sf( phx2 )

separate out the data frame from the map

d <- as.data.frame( phx.sf )

Hi Profs , @Anthony-Howell-PhD @lecy

I Have created my Dorling for the selected city, I store it in my local disk as below code, however, the map isn't showing as below, not sure what I'm missing.

# DATA STEPS 

# load Dorling cartogram from github
# map already contains census data and groups from clustering 

library( geojsonio )
library( sp )

WAHS <- geojson_read( "msp_dorling.geojson", what="sp" )

plot( WAHS )

# reproject the map 
WAHS2 <- spTransform( WAHS, CRS("+init=epsg:3395") )

# convert the sp map format to 
# an sf (simple features) format:
# ggmap requires the sf format
WAHS2.sf <- st_as_sf( WAHS2 )

# separate out the data frame from the map
d <- as.data.frame( WAHS2.sf )

However, the map isn't showing as below screen,

Hi Jay, Can you please email me your rmd file and the .geojson file of your selected location? I will take a look. Best,
