Compare Your Town Alongside The World



I've seen a fair few map comparing websites over the years, map applications that allow yous to compare 1 dry soil alongside some other dry soil or 1 metropolis alongside some other city. BBC DimensionOverlayMaps, MAPfrappe and If It Were My Home? are 4 skillful examples of apps that allow yous to compare 1 place alongside some other on hand of an interactive map.

All 4 of these maps operate past times overlaying the shape of 1 place on hand of some other thus that yous tin brand a straightaway comparing of size. Mapmerizer industrial plant a fiddling differently equally it lets yous compare ii locations side-by-side on ii dissimilar maps. Type inwards the refer of ii towns, cities or countries into Mapmerizer as well as yous tin compare a Google Map of each place juxtaposed side past times side to each other.

One great characteristic of Mapmerizer is that yous tin likewise compare the satellite views of your ii dissimilar locations. For example, when comparing the satellite views of London as well as New York, London seems much greener than the Big Apple, piece inwards New York the population appears to travel to a greater extent than densely concentrated.



The True Size of ... is 1 of the close pop size comparing interactive maps. This map allows yous to overlay the outlines of whatever dry soil (or countries) on hand of some other dry soil on a Google Map. You tin type whatever dry soil or province into the search box to add together its shape to the map. You tin thus drag the shape unopen to the map to compare its size to whatever other dry soil on the map.

The refer 'True Size of ...' is a flake of misnomer equally in that place volition ever travel some distortions when using a ii dimensional map. However The True Size of ... map does purpose the Google Maps API geodesic holding for draggable polygons. This way that when yous drag a dry soil unopen to on the map the polygon shape resizes equally yous motion due north or southward on the map, compensating inwards business office for the distortions inwards Google Maps' Web Mercator projection.


It is real slow to practice a dry soil size comparing map similar The True Size Of using the Google Maps API. Google's Maps API allows yous to define polygon shapes equally both draggable as well as geodesic. This way that if yous add together a dry soil polygon shape to a Google Map the map's users tin drag the shape unopen to the map as well as the size volition modify size depending on the shape's latitude.

In Leaflet.js in that place is no uncomplicated method inwards the platform's JavaScript library for making a polygon shape both draggable as well as responsive to the map projection. However yous tin purpose Webkid's plug-in for Leaflet which allows yous to add together draggable polygons that resize automatically depending on the score of latitude.

Leaflet Truesize includes links to download the plugin as well as an explanation of how it should travel used to practice a size comparing map. It likewise contains an instance map which allows yous to drag Republic of Republic of India as well as United Mexican United States of America on an interactive map thus that yous tin compare their size alongside other countries unopen to the world.
