Definition of map: diagrammatic representation of reality on a paper.
elements of a map: scale, direction, title, subtitle, ownership, key map, legend
contents of base map: boundaries
network, topography, landuse, contours, utilities
appropriate scales for various types of plan like regional plan, perspective plan, development plan, local area plan
measurement of sclaes: scale conversion from larger unit to smaller units and vice-versa
Landuse classification, Landuse Landcover (LULC) classification

3. Elements of Map
1. Title, sub-title
2. Direction
3. Scale
5. Key or
Inset Map
6. Prepared by
or ownership
4. Legend
4. Scales
Types Feature
1. Statement of Scale/ Word
scale/ Verbal
e.g. 1cm is equal to 100m
Easy to understand but tough to convert/
judge reality
2. Representative Fraction or
Numeric Scale
• Distance x : y
• Areal x2 : y2
• In Distance scale, units remain same in
numerator ‘x’ and denominator ‘y’
• Easier to read
• Universally accepted
• It changes with a little zoom-in or zoom-
out, a usual error in prints
3. Graphical
• Linear
• Bar
• Usually adopted for small-scale drawings
• Readability remains same even with zoom-
in/out or variation in print scale
• Chances of error are higher while
translating in reality
