This project is the culminating work of a graduate-level Urban Planning capstone developed at Columbia University's Graduate School of Architecture, Planning and Preservation. The project visualizes projected population density in West Africa using climate migration models developed by researchers at Columbia University's Center for International Earth Science Information Network (CIESIN), in partnership with The World Bank.
The current version displays the LLLH262 population model, a 'best case' scenario, as well as Hotspots at the 15 by 15 kilometer cell level, in five year increments from 2015 to 2050.
Hover over a cell to display additional information for each 225-square kilometer area in the sidebar. Use the slider to move through the timeline, and toggle Hotspots and 3D projections by clicking the buttons. You may pan and zoom using your mouse or touchpad, and rotate the map view by holding right-click and dragging the mouse.

This Hotspot data reflects degree of certainty based on the overlapping data from a series of independent climate models, including the LLH262. The higher the score, the more models indicate similar patterns in a given cell. The lower the value, the less corresponding overlap there is, thus the less certainty.
