Map is a drawn or printed representation of the physical features of the Earth.
It is the best tool to show, understand and analyse the features of an area. Cartography is the art and science of making maps. This module highlights many information on maps, types and their uses.
Topics:
1. Mapping Concepts
2. Analysis with paper based Maps
3. Limitations of Paper based Maps
4. Computer Aided Cartography History and Development
5. GIS Definition
6. Advantage of Digital Maps
A map projection is a systematic transformation of the latitudes and longitudes of locations from the surface of a sphere or an ellipsoid into locations on a plane. Maps cannot be created without map projections.

A map projection is a systematic transformation of the latitudes and longitudes of locations from the surface of a sphere or an ellipsoid into locations on a plane. Maps cannot be created without map projections.
A coordinate system is a reference system used to represent the locations of geographic features, imagery, and observations, within a common geographic framework.
Coordinate systems enable geographic datasets to use common locations for integration.
Map projection is a systematic drawing of parallel of latitudes and meridians of longitude on a plane surface for the whole earth or a part of it on a certain scale so that any point on the earth surface may correspond to that on the drawing.
Maps cannot be created without map projections. All map projections necessarily distort the surface in some fashion.
Depending on the purpose of the map, some distortions are acceptable and others are not; therefore, different map projections exist in order to preserve some properties of the sphere-like body at the expense of other properties.
There is no limit to the number of possible map projections.
One of most important topics in ArcGIS and GIS, is coordinate system, the slides will cover this topic in order to understand the difference between various coordinate systems.
Photograph taken from an aircraft commonly termed as aerial photograph have come to play and ever increasing role in the execution in cartographic mapping in various scales and in evaluation of natural resources of a region. Uses of aerial photographs in other fields are also manifold; in fact the scope seems limitless.
Cartography is the art, science and technology of map making.
Maps are used as research tools and as sources of information.
Maps have existed since the time of the Egyptian, Mesopotamian and Chinese civilizations, with the latter maps dating back to 6000 years.

The Map, Map Reading and Principles of Geography - World TourismCris dela Peña
Maps are the basic tools of the travel professional. Without them, it is next to impossible to locate cities or countries one may have never heard about. Bienvenido G. Claravall.
Message me if you want to have a copy of this presentation. Thanks.
This is the Presentation I gave at Nerd Nite Miami.
It's a very broad overview of the rationality movement. It talks very briefly about how we can learn to use our minds better by understanding their limitations and the ways they evolved.

1 How does a topographic map show the shape of the land sur.pdfcbholla1
1. How does a topographic map show the shape of the land surface? For example, how do
topographic maps indicate steeper slopes? How are gentler slopes portrayed? How can you
identify
stream or river valleys on maps?
2. What are contour lines? What is an index contour?
3. Define contour interval.
4. What does a fractional scale of 1:48,000 mean?
5. What is a bar scale and how is it used?
6. The basic unit of latitude and longitude is the degree. How is the degree subdivided?
7. Latitude is measured in degrees N or S of what line? What is the range of possible values (in
degrees) for latitude?
8. Longitude is measured in degrees W or E of what line? Where is that line located? What is the
range
of possible values (in degrees) for longitude?
Introduction Topograpbic maps illustrate scale, width, length, and height of landforms. Geologic
maps show the distribution of different rock units and geologic features, such as faults, at the
surface of the Earth. In this lab you will become familiar with both types of maps which are
important tools for anyone studying the earth or its resources. Learning Outcomes - Explain how
contours are used to show elevation information and landforms on a map. (questions 13) -
Understand and explain different types of map scale, such as fractional scale and bar scale.
(questions 4-5) - Explain how latitude and longitude are used to describe location. (questions 6-8)
- Draw and use contours to visualize spatial data (such as spot elevations). (question 9) - Find the
latitude and longitude of a location on a map. (questions 10, 17, 18) - Read elevation data and
interpret contours on a topographic map.(questions 11, 12, 19) - Calculate elevation change and
gradient (slope) from topographic maps.(questions 13, 21) - Read distances on a map using a
ruler and bar scale.(questions 14-16; 20) - Interpret ages of rock units on a geologic map
(questions 22-23) - Identify geologic structures on a geologic map (questions 24-27) - Draw a
geologic cross section using locations of contacts and angles of dip on a geologic map (questions
28-30) - Identify types of folds or faults on a geologic cross section (questions 28-30) Map
Coordinate Systems A coordinate system allows us to describe the location of any point on the
surface of the Earth. Lines of latitude (also known as parallels) are the horizontal lines that circle
the globe. These lines are known as parallels because the run in the same direction as (are
parallel to) the Equator. The Equator is the imaginary line located at 0 latitude and is halfway
between the North Pole and the South Pole, which are 180 apart. This means the South Pole is 90
S and the North Pole is 90N. Lines that run from the North Pole to the South Pole are lines of
longitude (also known as meridians). The line at 0 longitude is the prime meridian and runs
through the Royal Observatory in Greenwich, England. Meridians are counted east and west from
the prime meridian up to a maximum of 180 longitude at the.
Different types of Important projection systems & Coordinate systems.Every country would like to represent it's self in true shape, if shape changes then size , area also changes so that leads to distortions on the global properties of a map like Distance,direction,shape ,Area. so no country or continent will never like to represent themselves distorted , so hundreds of projections were developed by counties across the world.
Gives details about maps, projections,their uses and also about data presentation. Made for students for 11th and 12th standard. Also helpful for competitive examinations. This file is made from NCERT books of class 11th and 12th books titled "Practical work in Geography"
