Inspiration


This map is a followup to Wetlands of the US. The data provided the names of different features of the US. I then created Lakes and Ponds of the US. Nevertheless, the data also provided physical features like summits. This map includes features that are not only classified as summits such as cliffs. The names included were those classified as synonyms of summit. For a more detailed map of US elevation got to US Elevation Contour.

Resources


The data was downloaded from the Geographic Names Information System (GNIS), maintained by USGS. Data cleaning was done with R Project for Statistical Computing. At first I used only the data classified as summits, but then added other features like cliffs. The Shapefiles for political borders in this map were downloaded from Natural Earth. The elevation shapefiles were downloaded from USGS Science Base Science Catalogue.The code was obtained and altered from Chris Williams’s Block.
