Cartogram Maps: Data Visualization with Exaggeration
Cartogram maps distorts reality to convey information. It accomplishes this by resizing and exaggerating any variable using a polygons geometry.
Maps & Cartography
What is a Voronoi Diagram?
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.
Choropleth Maps – A Guide to Data Classification
Equal intervals, quantile, natural breaks, pretty breaks- data classification methods generate different choropleth maps. We explain the types of maps here.
Azimuthal Projection: Orthographic, Stereographic and Gnomonic
The azimuthal projection plots the surface of Earth using a flat plane. For example, common azimuthal projections are gnomonic, stereographic & orthographic
Equal Area Projection Maps in Cartography
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.
How Universal Transverse Mercator (UTM) Works
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.
What Is a Map Legend?
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.
10 Climate Change Maps – The Climate Explained
From crop production to melting glaciers, these climate change maps help your grasp a clear understanding of our transforming climate.
Cylindrical Projections in Cartography & Maps
When you place a cylinder around a globe and unravel it, you get the cylindrical projection like the Mercator, Transverse Mercator and Miller projections.
The Geoid – Hypothetical Mean Sea Level
The geoid measures mean sea level and gravity. The GRACE and GOCE satellites are providing the most accurate measurements of the geoid to this date.
