A grid system on a map is usually square and is represented by drawn lines on the map creating those squares. The purpose of the grid system is to give each point in the map an identifier, an address, by which we can refer to it by. Using the ruler, draw a rectangle on the map around the entire city area. Divide the rectangle into 1-inch grid squares. Beginning at the bottom, measure up 1 inch and draw a parallel line from left to right on the horizontal.
Measure up another inch and draw a parallel line until you have less than 1 inch to the top. Eastings are written before Northings. Thus in a 6 digit grid reference , the Easting component is and the Northing component is , i. A vertical line is a line, parallel to y-axis and goes straight, up and down, in a coordinate plane. Whereas the horizontal line is parallel to x-axis and goes straight, left and right. A vertical shape is a shape with layers stacked on top of each other, with a fixed layer height, for example a round tower where the radius corresponds to the datapoint.
The degree line is a single vertical line called the International Date Line, and it is directly opposite of the Prime Meridian. All rights reserved.

This system is just as useful for people on land when hiking, driving, or surveying an environment. To locate a point on a globe exactly, degrees of latitude and longitude are further subdivided into minutes and seconds. In latitude and longitude measurements, minutes and seconds do not refer to time. Instead, they refer to parts of an angle.
But, like with time, there are 60 minutes in a degree just as there are 60 minutes in an hour. Similarly, there are 60 seconds in a minute of time and 60 seconds in a minute of longitude or latitude. The latitude and longitude readings of a place are called its spherical coordinates. Make three maps of a globe: an orthographic-projection map, a cylindrical-projection map, and an equal-area map. If the latitude and longitude coordinates of a location are known, it can be pinpointed on a map or globe.
Knowing the spherical coordinates of a location is useful for people when hiking, diving, or surveying an environment. Sophisticated navigational aids use latitude and longitude to give directions when driving and flying. The spherical coordinate system is essential for ships at sea that cannot locate their positions using landmarks or coastal navigation aids like buoys or channel markers.
In addition to using latitude and longitude to specify location, marine and air navigators also use the nautical mile as their unit of length or distance.
A nautical mile is approximately one minute of latitude along a line of longitude, a distance of 1. Navigators describe the speed of ships and airplanes in knots. Meteorologists also describe wind speeds in knots. One knot is equal to one nautical mile per hour. This document may be freely reproduced and distributed for non-profit educational purposes.

Locale is the physical setting for relationships between people, such as the South of France or the Smoky Mountains. Finally, a sense of place is the emotions someone attaches to an area based on their experiences.
Place can be applied at any scale and does not necessarily have to be fixed in either time or space. Additionally, due to globalization, place can change over time as its physical setting and cultures are influenced by new ideas or technologies.
Learn more about the physical and human characteristics of place with this curated resource collection. Students discuss the meanings of terms location and place and identify whether descriptions are of location or place.
