The Maps Of The Week



Malfideleco was in all probability the most talked virtually map this week. However I retrieve its popularity was to a greater extent than to exercise amongst the involvement inwards the Ashley Madison hack rather than the character of the map. Therefore let's chop-chop motility on to the existent maps of the week.

EcoWest has released ii interactive maps which allow you lot to explore xv years of drought information together with 34 years of atmospheric precipitation data. The Tracking U.S. Drought Severity map visualizes the weekly drought designations from the U.S. Drought Monitor from the start of the 20th Century. Select a appointment from the timeline beneath the map together with you lot tin strength out sentiment a heat-map of the drought weather condition during that week.

The minute map, Rain together with Snow inwards the U.S. Since 1981, shows the full monthly pelting together with snowfall totals across the country. You tin strength out utilisation the timeline beneath the map to pick out a appointment together with sentiment a heat-map of atmospheric precipitation levels for the selected month. This fourth dimension the timeline includes a graph which shows the full rainfall for each calendar month since 1981.


Websites which allow you lot to conduct compare the sizes of ii or to a greater extent than dissimilar countries convey ever been a pop way to utilisation interactive map libraries. OverlayMaps, MAPfrappeMy Life Elsewhere, Mapmerizer and If It Were My Home? are 5 skilful examples of apps which allow you lot to compare 1 place conduct amongst some other on an interactive map.

The True Size of ... is a welcome add-on to this growing listing of province comparing maps. This map allows you lot to overlay the outlines of whatsoever countries on summit of some other province on a Google Map. You tin strength out type whatsoever province or province into the search box to add together its shape to the map. You tin strength out together with hence drag the shape around the map to compare its size to whatsoever other province on the map.

The True Size of ... map makes utilisation of the Google Maps API's geodesic belongings for draggable polygons. This way that when you lot drag a province around on the map the polygon shape resizes equally you lot motility N or southward on the map, compensating inwards role for the distortions inwards Google Maps' Web Mercator projection.


There didn't appear to endure much involvement inwards my ain Shifting Cites map this week. Therefore it is decidedly dodgy that it makes it to this week's Maps of the Week list. I suspect at that topographic point is some course of bias involved.

Since the early on years of the U.S. at that topographic point has been a gradual westward shift inwards the hateful marrow of population. In 1790 the most populated cities inwards the U.S. were all on the East Coast. In the 2010 census seven of the 10 largest cities were located inwards the Sunday Belt percentage of the southward together with west.

Shifting Cities shows the summit 10 most populated U.S. cities for every decade since 1790. The map too shows the hateful marrow of population inwards the USA for each decade.
