The Condition of Arizona…

Our Data set

Our Data set

The Arizona Drought Conditions Dataset is a comprehensive collection of data that provides crucial insights into short-term and long-term drought conditions in various counties within the state of Arizona.
The data is sourced from the Arizona Drought Monitoring Technical Committee, which convenes weekly to advise the U.S. Drought Monitor authors on the current drought conditions in Arizona.

First Question

What are the most affected areas in Arizona ??

The Code

# Reactive value to store the selected county
  selected_county <- reactiveVal(NULL)
  
  # Update selected county on map click
  observe({
    click_latlng <- input$map_shape_click
    if (!is.null(click_latlng)) {
      # Create an sf point object with the correct CRS
      click_point <- st_sfc(st_point(c(click_latlng$lng, click_latlng$lat)), crs = st_crs(arizona_counties))
      
      # Find intersection between point and counties
      intersecting_counties <- st_intersection(arizona_counties, click_point)
      
      # Take the first intersecting county (you might want to handle multiple results differently)
      selected_county(intersecting_counties$name)
    }
})
