I dearest the slide command inward these maps inward this Urban Institute interactive. Washington DC - Our Changing City is a written report on the population changes happening inward Washington DC.
The interactive written report includes a serial of maps comparison population as well as demographic changes inward the American working capital missive of the alphabet betwixt 2000 as well as 2010. Each map includes a slide command that allows the user to swipe across the map to compare the differences inward point maps from the twelvemonth 2000 as well as 2010.
I've seen this type of slide command used earlier to compare earlier as well as later photographs. For example, I used a like command to compare aerial imagery from earlier as well as later the 2011 tornado inward Tuscaloosa. However this is the offset fourth dimension I've seen a slide command used to compare 2 dissimilar map layers.
