In a previous task sheet, Shapefile to GeoJSON: Conversion and Visualization PM 2082-15G you learned how to convert a point data file into a GeoJSON file format and visualize it with geojson.io and GitHub. In this task sheet you will learn how to add a GeoJSON data file to a basic leaflet then filter the data to display.

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