Cartographers use lines to show the movement of phenomenon (people, ideas or money) in flow maps. To show the magnitude, they change the width of flow lines
Cartogram maps distorts reality to convey information. It accomplishes this by resizing and exaggerating any variable using a polygons geometry.
In a Voronoi Diagram, when you take a point in any given Thiessen polygon, it indicates that it’s closer to that generating point than to any other.
Equal intervals, quantile, natural breaks, pretty breaks- data classification methods generate different choropleth maps. We explain the types of maps here.
The azimuthal projection plots the surface of Earth using a flat plane. For example, common azimuthal projections are gnomonic, stereographic & orthographic
The equal area projection retains the relative size of area throughout a map. So that means at any given region, it keeps the true size and area of features.
Universal Transverse Mercator (UTM) segments the Earth into 60 zones (each UTM zone is 6°) and projects each zone with an upright cylinder of its own.
A map legend is used to define features in a map. Point, line and polygon symbols in a legend key is the driving-force to understand what is found in a map.
From crop production to melting glaciers, these climate change maps help your grasp a clear understanding of our transforming climate.
When you place a cylinder around a globe and unravel it, you get the cylindrical projection like the Mercator, Transverse Mercator and Miller projections.
