This document summarizes the cartography work done for the May 2016 issue of National Geographic Magazine on Yellowstone National Park and elk migration. It lists the creators of the magazine page maps, a supplement map of elk migration, and interactive maps. It then provides details on the techniques used to create a locator map, base map, animation of elk migration, and multiscale raster processing. Additional contributors to the project are also listed.

48. HOW TO LEVERAGE IN-
HOUSE CARTOGRAPHY
FOR WEB MAPS?

49. — WEB —
D3 - GeoJSON, SVG/Canvas
LEAFLET - Tiles, Vectors
Pre-rendered map data, in raster & SVG
HTML/CSS/Javascript
MAPBOX - Vector Tiles of OSM & own data
CARTO(DB) - Similar, better data processing
GOOGLE MAPS - Limited customization, can overlay data
DESKTOP - COMMAND LINE - SERVER SIDE SOFTWARE
arcgis, qgis, gdal, ogr2ogr, mapnik
mapublisher, geographic imager, node, python…

60. LOCATOR MAP
Data: Generalized North America boundaries,
borders, elk range data; conic projec%on
Format: Shapefile to GeoJSON to TopoJSON.
Tech: Javascript / D3 / Canvas

61. BASE MAP
Data: Snowfall, NDVI, Na%onal
Hydrography Dataset, Admin
boundaries, Gov't parks boundaries;
Yellowstone Equal Area Projec%on
Format: GeoTIFF to re%na %lesets
(jpeg)

62. ANIMATION MIGRATION
Data: Processed GPS tracks from hundreds of tagged
elk
Format: Shapefile ➡ GeoJSON ➡ Generalized
temporal JSON of GeoJSON
Tech: Canvas, Leaflet, D3 (browser: graph), proj4js, D3
(Node), Lodash (Node), Bluebird, MomentJS, Gulp

63. MULTISCALE PROJECTION AGNOSTIC RASTER
PROCESSING
Data: GeoTIFF files represen%ng the same
geographic area at different scales
Format: Structured folders of geo%ff to WMS %le
sets + metadata for proj4leaflet to consume
Tech: Bluebird, Node GDAL, ImageMagick,
GDAL2Tiles (modified), proj4leaflet, proj4js,
