Assignment 4

1. Leaflet Map with Markers

The map below displays the various locations I visited during my field trips while studying at Korea University.
To create this map, I made a CSV file containing the longitude and latitude of each location.
I added custom book icons that represented each site.
Additionally, I included a control that allows users to select from one of five base maps: OSM, Aerial, TopoMap, Terrain, and MainRoad.
To provide more information about each location, I added pop-ups that display the name of the site and its type.
Finally, to ensure optimal functionality, I applied a cluster function to the map.

2. Leaflet Choropleth Map

The interactive map shows the proportion of Black K-12 students in each Iowa county,
with pop-ups displaying county names and corresponding percentages.
The legend is located on the bottom right of the map for reference.
Additionally, a toggle button has been added to the top left of the map to indicate the location of Iowa State University.
(The toggle button was added as an application of the knowledge gained from lectures and personal study.)
