Chapter 1 General Flashcards
This publication is intended for the use of all map users, however its primary purpose is to provide instructors in map reading with a comprehensive book of reference. The publication covers only the factual information common to most maps, leaving the full understanding of map reading to be attained by practical instruction and by personal experience. To be truly effective, much of the instruction must be conducted on the ground.
What is the basic requirement of
map reading?
The full understanding of the information shown on the map.
The reading of map information includes the ability to_________.
Locate and to give map references,
the understanding of scales and the use of them for measurements, position findings and the
description and navigation of routes by day or by night.
Mapcraft
The ability to obtain from the map a mental picture of the ground portrayed.
Under this system Canada is divided into numbered
quadrangles each 4° latitude by 8° longitude (16° longitude
north of 80°).
The National Topographical System
In regards to the The National Topographical System figure 1-2:
What is 54?
54 is a primary quadrangle and denotes a map
of the 1:1 000 000 series.
In regards to the The National Topographical System figure 1-2:
What is 54 S W?
54 S W is a quarter of a primary quadrangle
and denotes a map of the 1:500 000 series.
In regards to the The National Topographical System figure 1-2:
What is 54 H
54 H is a lettered quadrangle and denotes a
map of 1:250 000 series. South of 68° maps
are one- sixteenth of a primary quadrangle
and lettered A to P. North of 68° maps are
one-eighth of a primary quadrangle and
lettered A to H.
In regards to the The National Topographical System figure 1-2:
What is 54 A/N.E?
54 A/N.E is a quarter of a lettered
quadrangle-denotes a map of 1:125 000
series.
In regards to the The National Topographical System figure 1-2:
What is 54 A/8A?
54 A/8A is a sixteenth of a lettered
quadrangle and denotes a map of 1:50 000
series.
In regards to the The National Topographical System figure 1-2:
What is 54 A/8a?
54 A/8a, denotes a map of the 1:25 000
series, which is one-eighth the area of a 1:50
000 quadrangle and is identified by a
lowercase letter suffix.
T/F Some 1:50 000 scale maps were produced as two map sheets an East half and a West half
Topographical Map Coverage International.
True
T/F Maps of the World at the scale of 1:1 000 000 are not complete
True
T/F Maps of the World at the scale of 1:1 000 000 are complete
False
T/F From the lines and symbols on a map it is relatively simple to gain a mental picture of
natural detail, such as woods and streams, and man-made objects like roads and buildings.
True
T/F Real mapcraft, however, lies in the ability to visualize the shape of the ground, which is shown on the map by contours and spot heights.
True
T/F The reading of contours and the ability to gain from them a mental picture of the ground
cannot be taught from a textbook.
True
T/F The reading of contours and the ability to gain from them a mental picture of the ground
can be taught from a textbook
False
T/F All maps are not to the same standard of accuracy, reliability or currency
True
T/F All maps are to the same standard of accuracy, reliability or currency
False
The information required to assess a map
a. dates of surveys or of other maps from which the map has be compiled;
b. date and extent of the last revision; and
c. overall map detail.
Topographical maps
Topographical maps are the types of map to present a picture of the ground as it exists.
What do topographical maps contain?
Physical features of the ground and man made features.
They also contain a large number of names, both
specific names of towns, villages and rivers, and also descriptive names of general features such
as railways, fords, post offices, etc.
What scale do topographical maps vary from?
1:25 000 to 1:250 000.
What are the map series commonly used by the CF?
a. Training Area Map (Canada). 1:50 000;
b. Foreign 1:50 000; and
c. Military Town Plan (Canada). 1:25 000.
T/F On topographical maps, vertical information is not normally shown
True
T/F On topographical maps, vertical information is normally shown
False
Maps on Scales Smaller than 1:250 000.
These are used for strategic planning
and by air forces. Map detail is generalized and only principal features are shown.
Relief, if shown, is normally indicated by layer tints (see paragraph 14) or by
other means.

Special Maps
These include maps to illustrate special items of information, for example, road maps, going maps (to show suitability for vehicular cross-country movement), railway maps and skeleton maps (showing only water and relief).
The panorama sketch is a very practical expedient for use in ________________.
In an artillery observation
post (OP) for displaying targets and target data related to the zone it overlooks.
