The importance of map

This article is talking about the importance of maps. It tells us the history and usage of map. After reading the map, you will learn how important the maps is in our daily life. It brings us much convenience.

1. The importance of map
Human use map already has a very long history. But until modern times , the
map was printed as a document . Map was drew on the paper or other
material sheepskin upper roads, settlements and natural elements , etc. - so ,
so people describe the real world by using maps .
With the development of maps, humans learned to use a wide variety and
creative way to express the real world. Cartography has also accumulated
many methods of describing elements for classifying elements, identity
recognition, the shape of the Earth's surface in the flow of resources and
goods.
With the popularity of computers and geographic information systems (GIS)
technology, the map has now become very familiar prints and maps can be
interactively visualized displayed on the computer .
GIS Further strengthen the interaction between humans and maps . In GIS,
You can easily identify the information that expression on the map , you can
also easily select query and analysis by location.
Map has a variety of ways to express the unique features of the real world .

2. Maps can also identify something in a certain position. On the map , you point
to any location , you are able to know the name of the place or object as well
as other relevant property information. Maps can indicate your location. If you
enter a map in real time Global Positioning System (GPS) data, you can see
where you are and how fast to travel and destinations where your journey .
Map allows you spatial distribution , relationships and trends that can not be
finished by other ways . By comparing urban demographer maps and city
maps in the past, it turns out that can support public decision-making .
Epidemiologists can find out the rare disease by associating with
environmental factors surrounding.
Maps can integrate data from different sources to the same geographic
reference coordinate system. Municipal street maps can be layout and
combine to adjust the municipal building structures ; agricultural scientists can
combine the weather satellite image maps and farm to increase crop yields.
Maps can be merged or superimposed data to analyze spatial problems .
Government can find a suitable waste disposal sites by combining multi-
layered data.
Maps can be used to determine the best route between the two places .
Through the map , parcel courier companies to find the most effective

3. transport path ; public transportation designer can design the optimal bus
routes
Maps can be used to simulate the future. Public utility service companies can
simulate how kind of effect it will be when add the new facilities, and
determine whether you need to invest based on this effect. Municipal planners
can also simulate some serious accidents , such as leaks and other toxic
substances , and thus draw the appropriate solution.
The development of GIS technology has broaden people's eyes on the map .
By comparing purely static entity with the past , and now the map has become
a geographic information dynamically primary means of expression. The map
is a method of graphical representation. For achieving better results of
information representation, the map must have a strong visual appeal . In
addition, a lot of experience in graphic design , such as layout , scale, color
balance, symbols, and layout are all being applied to map production.
Maps can be understood as the media of between " geographic information "
and " understanding of human information ". Map borrows recognizable
human-specific spatial pattern perception, provide visual information about the
circumstances of geographic objects and locations.
Map is the abstract of geographic information. The users of the map is

4. different, so they get the definition of the map is different. For the specific
purpose of use , the performance of the map information is particular. Maps
simplified the complex internal structure hidden data. Also, you can describe
the data on the map - such as showing the name, categories, types, labels
and other information.
The purpose of data modeling is a way to create a design which contains a
wealth of information and aesthetic characteristics of map data structure.
Understanding the way of maps express information is the prerequisite to
create the "right " data model.
In a word, map is essential to us in our daily life.
