**Map Projections**
– All world maps are based on various map projections.
– Map projections distort geographic features, distances, and directions.
– Mercator Projection is a well-known projection originally designed for nautical charts.
– Other projections include Mollweide, Cahill Butterfly Map, Polar azimuthal equidistant, and Robinson.
– Different projections balance accuracy and distortion in different ways.
**Thematic Maps**
– Thematic maps focus on specific geographical subjects.
– They can portray physical, social, political, cultural, economic, or agricultural aspects.
– Early world maps depict the world from the Iron Age to the Age of Discovery.
– Old maps provide insights into past knowledge and cultural influences on cartography.
– Maps are a means for scientists to share ideas and knowledge across generations.
**World Map Content**
– A world map covers most or all of Earth’s surface.
– World maps deal with projection issues due to rendering in two dimensions.
– Techniques have been developed to present world maps with diverse goals.
– Creating an accurate world map required global knowledge of Earth’s features.
– Maps generally focus on political, physical, geological, or choropleth features.
