Map Projections A way of representing the earth’s curved surface on a flat surface of map is known as map projections. A globe represents the most accurate position‚ place of different things present on earth but a globe is not practical for many of the functions for which we require a flat map. Map projections help us to represent most of the earth’s surface at a wide variety of scales‚ on a flat‚ easily transportable surface. A globe is the true representation of distance‚ direction‚ area‚

plane in which the Earth revolves around the Sun). • Right ascension is analogous to longitude and is measured in hours‚ minutes‚ and seconds‚ from the point of vernal equinox. • Declination is analogous to latitude and is measured in degrees from the celestial equator. • Measurements of declination are either positive (north) or negative (south). • Note: 1 hour = 15° of arc (1° arc is equivalent 1° of longitude) and 1 minute = 1/60° of arc. • Example: Proxima Centauri has a declination of -62°40’

Open the flat map explorer. Familiarize yourself with the cursor and how it prints out the longitude and latitude of the active map location. Note that you can vary the central meridian of the map (i.e. change its longitude). Use the “shift map” arrows at the top of the simulator to affect large rapid changes. Use the
