How are longitude and latitude measured and how are places located?

Civilian UTM
• The grid is at Zone 14, 357 000, 5 476 000
• The church is at Zone 14, 357 400, 5 476 200

Military Grid
• The church is in grid 9194

Military Grid
• The church is located at 916944.
• However, as grid numbers repeat themselves every 100,000 meters, it is necessary to use a different method.

Military Grid
• Here the church would be in square NT99 and more precisely at point NT9293.

Maps
• illustrate the spatial distribution (i.e., geographic pattern) of almost any kind of phenomena
• Maps provide a wealth of information. The information called spatial data.
• Any object or characteristic that has a location can be considered spatial data.
• The data can be qualitative (buildings, rivers, roads) or quantitative (elevation, air temperature, population density).

• Attempt to preserve one or more of the following:
• Area• shape• Direction• Bearing• Distance• Scale

Map Scale
• Expressed as a linear scale, a statement, or a fraction:
• E.g.:
• 1:1,000,000 [1cm on map=1,000,000 cm on earth]
• 1: 100,000
• 1: 25,000
