Map of usa with longitude and latitude lines. Interactive world map scavenger hunt this activity allows students to answer questions as they explore the interactive map of the world. In order to define where we are on the surface of this sphere we use a system of coordinates called latitude and longitude. Ignore the satellite pointing angles until you are familiar with finding your latitude longitude location. He has more than 20 years experience in data analysis bi databases programming and development mostly on microsoft technologies.
Latitude and longitude are at the core of map reading in that they are the imaginary lines which lay on the surface of the earth to form a matrix of coordinates. Though these lines may appear to have varying curvature the lines are actually circular in nature with different radii and are parallel to one another. Longitude shown as a vertical line is the angular distance in degrees minutes and seconds of a point. Or centre the map around lat long.
Lines of latitude are often referred to as parallels. Latitude shown as a horizontal line is the angular distance in degrees minutes and seconds of a point north or south of the equator. This map displays the geographical coordinates the latitude and the longitude of the world. He has a bsc in computer engineering.
The most common latitude and longitude map is a 124000 scale and the actual map size is about 22 inches by 27 inches. Longitude l lines of longitude appear vertical with varying curvature in this projection but are actually halves of great ellipses with identical radii at a given latitude. If you want dish pointing select the satellite and click the map afterwards. The earth is almost a perfect sphere.
