10C3 More on toposheets
Due to lot of requests, I’m updating my geoblog. Many of you have asked me to publish more toposheets. Here I am!
Let us look at this toposheet. Double click on this toposheet. You will see the enlarged topomap. Let us look at the Northern part of the toposheeet- see various features. Can you see QC,- What is it?
QC means that there is end of numbering of northing or easting i.e 0-99 on a toposheet it is written after every 100km. Here it is the end of northings.
Look at the town Panthawada- It has a police station (PS), Post Office (PO), well connected roads. a temple, perennial wells, etc.
Now let us to to the north-east of the map. What do you see over there? -
OPEN SCRUB- What does it mean? It indicates desert or semidesert condition. The occupation in this area would be sheep or goat rearing.
You will also see Lime Kiln- It is a furnace for baking limestone.Its presence shows the trade possibilities and the people working in it.
Let us study 6 figure grid reference. Look at the triangulated height of 224. Let us first find out four figure grid reference. Let us see the eastings first. We locate it in easting 82. Let us see the northings. It is in northing 94. So four figure grid reference of the triangulated height is 8294. Now how do you find four figure grid refernce. We have already found out the four figure grid refernce. (8294) Let us divide that square (8294) into 10 equal squares as it is I have done in the toposheet. Look at it closely. For every 2 cms, you mark one square. So you will have 10 equal squares. For 6 figure grid reference, first 3 figures are of eastings and the second part of the 6 figure reference is of northings. We have already know easting is 82. Let us now find out the third figure from those small squares. Its in first square. So first three figures are 821 and the second part is 941. So six figure grid reference is 821941 or 822941. Did you get it? I hope so anyway.
Can you see the broken ground? (I have marked in the toposheet) What is a broken ground? They are generally found along the banks of a river. Broken ground is caused by erosion during rain when the river is in flood. It usually happens in the area devoid of vegetation.
Ok, I will upload more toposheets tomorrow. Do mail me or scrap me. It will be my honour to help you. For further clarifications, send me a message- brhector21@gmail.com

MANUFACTURING INDUSTRIES-SHORT NOTE
The location of the industries is largely governed by two sets of factors and they are:
1. Geographical Factors
2. Non-Geographical Factors
Geographical Factors : The main geographical factors include raw material, power, labour, transport, market, cheap land and labour.
i. Raw Materials:
a. To minimize costs the industries using heavy or weight-losing raw materials are located in the regions where raw materials are located.
b. For example
i. Sugar mills in India are located in sugarcane growing areas,
ii. Pulp industry, copper smelting and pig iron industries are located near their raw materials,
iii. Iron and steel industries are located near iron ore and coal.
ii. Power:
a. Some manufacturing industries are located near sources of power because they require huge amount of electricity,
b. For example
i. Aluminium and synthetic nitrogen manufacturing industries.
iii. Market:
a. Nearness to markets provides easy outlets for manufactured products.
b. For example -i. Heavy machine, tools, chemicals industries are located near the high demand areas.
ii. Cotton textile industry is generally located in large urban centre;
iii. Petroleum refineries are also located near the markets.
iv. Transport:
a. All major industries are located on the trunk rail routes due to easy accessibility from these nodal points.
b. For example: i. Industries are concentrated in Mumbai, Chennai, Delhi and Kolkata.
v. Labour:
a. Industries require skilled labour. Quantity and quality of labour decides the location of industries.
vi. Historical Factors:
a. Older industrial areas are now the main industrial nodes of India.
b. For example
i. Mumbai, Kolkata and Chennai have large concentration of industries due to colonial past.
vii. Industrial Policy:
NON-GEOGRAPHICAL FACTORS
The non-geographical factors include capital, industrial policy, industrial inertia, banking facilities, insurance and political stability.
1. Capital: The capital intensive industries require huge capital, these industries are mostly located near the cities.
2. Industrial Policy: The ultimate decision on location of industries depend on the industrial policy of the government.
b. For example - i. Iron and steel industry in Bhilai and Rourkela were located to develop backward tribal areas of the country.
3. Industrial Inertia: The industries are most likely to develop at the place of their original establishment.
4. Banking Facilities: The areas having better banking facilities are better suited to establishment of industries.
5. Insurance: Insurance of the industries and the labour are the also important factors affecting the location of industries.
6. Political Stability: Industries are set up in the areas of political stability.
- India ranks ninth in the world crude steel production.
- India ranks first in the production of sponge iron.
- Steel Authority of India (SAIL) handles marketing strategies for Public sector and TISCO markets its products through Tata Steel.
- China is the largest producer and consumer of Steel.
- The major iron and steel plants are:

- Aluminium Smelting:
- Aluminium is used in the manufacture of aircrafts, wires, utensils, surgical instruments and electrical appliances. Aluminium has become important because:
- It is light
- It is resistant to corrosion
- It is a good conductor of heat and light
- It is malleable
- It becomes strong when mixed with other metals
There are 8 Aluminium Smelting plants in the country. Regular supply of electricity and raw material are the basis for location of this industry.
Q. Name the raw material essential for iron and steel industry.
Ans. Iron and steel industry needs iron ore, coking coal, limestone, dolomite, manganeseand fire clay. All these raw materials are gross (weight losing); therefore, the iron and steel plants are located near the source of raw materials.
Why most of the iron and steel plants of India are located in the peninsular plateau?
Ans. Iron and steel industry’s location is influenced by:
1. Gross Raw material: It requires iron ore, coal, limestone and manganese as a raw material. These are weight-losing (Gross) raw material therefore these industries are located near the source of raw material.
2. Assembly Cost: Iron and steel plants are located at place where assembly cost of the raw material is lowest. Some steel plants are located near coal fields or near iron ore producing areas.
3. Transport: All the plants are located on trunk rail routes which connects them to large urban markets. These conditions are favourably found in the peninsular plateaus.
(b) Chemical Industry:
- It is a combination of organic substances like petrochemicals and inorganic substances like sulphuric acid, nitric acid, alkalies, soda ash etc.
- Contributes 3% of GDP.
- India ranks third in Asia and twelfth in the world in terms of size.

o India exports to USA, Canada, Russia, United Arab Republic, UK and Australia.
c.SUGAR INDUSTRY
- India accounts for about one-fourth of the world sugarcane. India is the world largest producer of sugarcane and sugar.LocationUttar Pradesh and Bihar in north India and in south India Maharashtra and Tamil Nadu are the chief producers. Sugar industries are mainly located near the sugar cane producing areas because:
1. Sugar Industry is based on sugarcane, which is a weight-losing raw material.
Sugarcane cannot be stored for long as the loss of sucrose content is inevitable. - India stands first in the production of Gur and Khandsari.
- India stands second in the production of Sugar.
- There are 460 sugar mills in the country.
- This industry is seasonal in nature.
- Problems faced by this industry are:
- Seasonal nature
- Old and inefficient methods of production
- Transport delays
- Less demand for baggase.
- Q. Why sugar industries in India are located within the cane producing regions?
- Ans. Sugar industries are located in cane producing regions because i.
- Sugarcane is a bulky crop therefore it is difficult to transport.
- ii. Sugarcane is a weight-losing crop.
- iii. The sucrose content in sugarcane begins to dry during its transport after its harvest.
- iv. Better recovery of sugar is dependent upon its being crushed within 24 hours of its harvesting.
- v. The ratio of sugar to sugarcane varies between 9 to 12 per cent depending on its variety.
Knowledge based Industry:
- This electronic industry produces many equipment required by the telecommunication industry.
- Bangalore has emerged as the electronic hub of the country.
- Q. What is the major impact of Information Technology (IT) in India’s economy?
Importance of Manufacturing Manufacturing industries are the backbone of development in general and economic development in particular. Efficiency and competitiveness are the two factors that should be taken care of in manufacturing sector. Agriculture and industry go hand in hand and are supplementary to each other.
