The code for this task sheet (layerControlLeaflet.html) and previous task sheets can be found on the ISU Geospatial Technology Program GitHub page at: https://github.com/ISUEOGTP/GISTaskSheets.

This task sheet demonstrates how to manage map layers with Leaflet to allow users to toggle map data on and off and switch between basemaps. You will be building a fictitious weather alert map that provides a weather radar layer, sites of interest and alerts.
