• MAP, either in graphical format or digital
format , is the end product of surveying/
measurement process
•The spatial information on the map of the
surveyed area is needed for design,
construction as well as monitoring of the built
structures
LECTURE 3

4. 4
MORE on THE USE OF MAP
•RECORD SPATIAL INFORMATION ( COORDINATES OF POINTS)
•TOOL AID FOR NAVIGATION
•TOOL AID FOR PLANNING AND PHYSICAL DEVELOPMENT /
ENGINEERING PROJECT
•SIMPLIFY COMPLEX DATA/INFORMATION, E.G DISTRIBUTION OF
DISEASE
•VISUALISE ENVIRONMENTAL CHANGE
•PATTERN STUDY, EG. POPULATION STUDY,etc

TYPE OF MAP
BASED ON:
SCALE
GRAPHIC
INFORMATION

6. 6
TYPE OF MAP- SCALE
SMALL SCALE: 1:500,000 TO 1: 2 MILION
E.G: WORLD MAP
MEDIUM SCALE: 1:50,000 TO 1: 500,000
EG: TOPOGRAPHICAL MAP
LARGE SCALE : 1:10,000 TO 50,000
EG: TOWN MAP

LARGE SCALE MAP IS ALSO KNOWN AS PLAN

7. 7
TYPE OF MAP - GRAPHIC
GRAPHIC
3D: TOPO MAP, TO REPRESENT THE NATURAL
AND MAN MADE FEATURES
2D: PLANIMETRIC MAP, SHOWN LOCATION EG:
TOWN PLAN, ROAD MAP

8. 8
TYPE OF MAP - INFORMATION
•TEMATIC MAP: SPECIAL PURPOSE MAP EG : TO SHOW
THE DISTRIBUTION OF POPULATION, INCOME,
DISEASE,ETC.
•GEOLOGICAL MAP: TYPES OF SOIL
•HYDROGRAPHICAL MAP/CHART: SEABED, SHIP
ROUTE, ETC
•SURVEY MAP: CADASTRAL PLAN, SITE MAP
