1. by Eugene Rose M. Magtoto

2. Is a
diagrammatic
representation
of an area of
land or sea
showing
physical
features,
cities, roads,
etc.
MAP WHAT IS MAP?

3. Is the area
near or
surrounding
a particular
place.
VICINITY WHAT ABOUT VICINITY?

4. Person using maps, such as technicians and
engineers, should be familiar with map types and
symbols used in map work.This report will give an
overview of the classification and types of maps,
with some examples. In this report, it is not
intended to make you an expert in the construction
or use of maps, but to give you a background and a
working acquaintance with various kinds of maps.

5. There are MAPS that are required for DIFFERENT
purposes.

6. • Large areas
and
consequently
must be scale
to small.
• Shows
important
town and
cities, streams
and bodies of
water, political
boundaries,
and relief.
Classification
of Maps
1. GEOGRAPHICAL MAPS

7. • Complete
description of
certain areas.
• Shows the
larger scale of
the
geographical
positions of the
natural and
constructed
features of the
earth.
Classification
of Maps
2. TOPOGRAPHIC MAPS

8. • Working maps
for engineer
projects .
• Design for
specific
purposes to aid
construction.
• Provides
accurate
horizontal and
vertical control
data and show
objects on the
site.
Classification
of Maps
3. ENGINEERING MAPS

9. • Represents
features on the
earth’s surface
from aerial
photographs.
• Perspective
photographs
that are obtain
by stereoscopic
instruments.
Classification
of Maps
4. PHOTOGRAMMATIC MAPS

10. • Very accurate
control maps
for cities and
towns.
• They are used
to control city
development
and operation.
Classification
of Maps
5. CADASTRAL MAPS

11. • Deals with
information
concerning
mainly, bodies
of water, such
as shorelines,
sounding
depths,
navigation
aids, and water
control.
Classification
of Maps
6. HYDROGRAPHIC MAPS

12. • Nautical maps
or charts shows
aids to water
navigation,
such as buoys,
beacons,
lighthouses,
lanes of traffic,
shoals, and
radio compass
stations.
Classification
of Maps
7. NAUTICAL MAPS

13. • Aeronautical
maps or charts
gave
prominent
landmarks of
the terrain.
• Accentuate the
relief by layer
tints, hachures,
and contours
as aids to air
navigation.
Classification
of Maps
8. AERONAUTICAL MAPS

14. • Contains
information of
military
importance in
the area
represented.
Classification
of Maps
9. MILITARY MAPS

15. There are MAPS that are required for DRAWING
purposes.

16. Are distinguished
by the presence of
the “contour lines”
running through
out the map.
“Contour” is a
theoretical line on
a map joining
points of equal
elevation on the
surface of the land
above or below
sea level.
TOPOGRAPHIC
DRAWING WHAT IS IT?

17. They are used to
represent
characteristics on
earth’s surface,
to resemble
somewhat the
features or
objects
represented as
they would
appear in plan or
in elevation.
TOPOGRAPHIC
SYMBOLS WHAT IS IT?

18. 1. CULTURE, or CONSTRUCTED FEATURES
2. RELIEF
3. WATER FEATURES
4. VEGETATION

23. Now that we’ve learned a few and classifications
of the MAPS. What does it apply to our subject?
How do these things can be of advantage to our
studies?

24. There are MAPS that are required for PLOTTING
purposes.

25. A map plotted
from a plane
survey and
having the third
dimension
omitted is called
“plat or land
map.” Or simply
a plot of land.
PLAT WHAT IS PLAT?

26. 1. Plat of a Survey
2. Industrial Plats
3. Plats of Subdivisions
4. Plat showing a sewer plan
5. Plat showing Horizontal Control

27. The plat of a
survey should
give all the
information
necessary for the
legal decryption
of a parcel of
land.
Types of
PLATS 1. PLAT of a SURVEY

28. It represents also a
plant-valuation
map, a type of plat
often required. the
map might
included pipe
lines, fire
hydrants, location
and description of
buildings, railroads
and switch points.
Types of
PLATS 2. INDUSTRIAL PLATS

29. Are filled with
country recorder
for record and
must be
complete in their
information
concerning the
location and size
of the various
lots and parcels
composing the
subdivisions.
Types of
PLATS 3. Plats of Subdivision

30. Shows the general
treatment
involving sewer
lines. Contour lines
are often included
on sewer plan.To
show the entire
sewer plan would
be impractical
because to fit the
page size of a text,
details would be
so small as to be
unreadable.
Types of
PLATS 4. Plat showing a Sewer Plan

31. Horizontal
Control is a
system that
provides points
of reference for
surveys.These
accurately
located controls
can be thousands
of feet apart, but
serve to place all
intervening
points in context.
Types of
PLATS
5. Plat showing Horizontal
Control
