Study Notes
Geographic Coordinates and Reference Lines
- New York City's geographic coordinates: 40.7° N latitude, -74.0° W longitude.
- The heavy red line in geographic maps serves as a primary reference for measuring latitude, known as the Equator.
- The Equator is situated at an angular degree of 0°.
Longitude Reference
- The heavy red line for measuring longitude is called the Prime Meridian.
- The Prime Meridian also has an angular degree of 0°.
Map Data and Assessments
- Satellite imagery is the type of map data utilized in geographic figures.
- Estimated distance between Los Angeles, California, and London, England, is approximately 5,400 miles.
- Estimated distance between Tokyo, Japan, and Lisbon, Portugal, is about 11,000 kilometers.
Distortion in Mapping
- Flat world maps distort the representation of spherical globes, causing measured routes to appear curved, particularly noted in routes from Tokyo to Lisbon.
Remote Sensing and City Populations
- The "Recent Weather Radar Imagery" layer shows remote sensing datasets.
- The largest dots on city population maps represent cities with over 14 million inhabitants, predominantly found in southeastern Asia.
Tsunami Impact
- The Tohoku tsunami waves were highest in Hawaii, indicating significant impact in that region.
- Data showing the most affected city by tsunami waves includes Tohoku, Japan, based on the relevant tsunami data layer.
