Historical maps

These are map images preserved from the original CDs. They are shown for historical reference only. They have not been aligned with modern coordinates and are not used to plot bird locations.

Technical details

These five historical base-map image assets were recovered and preserved under accepted task T-10 (corrigendum v0.3). None has been calibrated, georeferenced, or selected as a rendering base map, and no coordinate or occurrence point is plotted on any of them.
