Five Years of Drought Web Map

A 30KM hexagonal net was cast over the Untied States, aggregating all instances of drought within each zone. At broader scales, a bi-variate set of points shows proportional time spent in drought, while color characterizes the cumulative intensity of that drought. At finer scales, the point symbols are replaced with direct labels of drought proportion.<div><br /></div><div>Source historic drought data: <a href='http://droughtmonitor.unl.edu/' style='line-height: 1.75667;' target='_blank' rel='nofollow ugc noopener noreferrer'>http://droughtmonitor.unl.edu/</a></div><div>Derived hexagonal aggregation feature service: <a href='http://nation.maps.arcgis.com/home/item.html?id=07041e4b5d9943bca5c06c6e125cda59' style='line-height: 1.75667;' target='_blank' rel='nofollow ugc noopener noreferrer'>http://nation.maps.arcgis.com/home/item.html?id=07041e4b5d9943bca5c06c6e125cda59</a></div><div>This web map is used as an interactive component of this Cascade story map: <a href='https://nation.maps.arcgis.com/apps/Cascade/index.html?appid=a9d345446d1a48a2918ff95b51f5841c' style='line-height: 1.75667;' target='_blank' rel='nofollow ugc noopener noreferrer'>https://nation.maps.arcgis.com/apps/Cascade/index.html?appid=a9d345446d1a48a2918ff95b51f5841c</a></div><div><br /></div>
