The map above was created from the Mapbox template style "Terrain." A tileset was created by uploading a zipped shapefile of 10 foot contours generated in ArcPro, clipped to a 2500 foot radius of Copperas Creek Falls, and reprojected to the Mapbox web mercator projection. These were styled so that the 100 foot index contours are bolder, and have elevation labels. The elevation data was derived from lidar point cloud data maintained by Kentucky's Elevation Data & Aerial Photography Program (KyFromAbove).
"Falls" features were extracted from a text file downloaded (October 2018) from the Domestic and Antarctic Names (State and Topical Gazetteer) published by
the United States Board on Geographic Names (geonames.usgs.gov), and saved to a .csv file, using Python code.
Geographic points were created from latitude and longitude fields in the text file.
