Tourism Geography and IATA Areas
What it is
Unit II is tourism's spatial toolkit: Earth's movements, IATA areas and codes, time zones and journey-time arithmetic, world and Indian climate and landforms as the resource base of destinations, and the drivers of tourist flows with the laws that limit them.
Core concepts
Earth's movement, latitude and longitude. Earth rotates west to east once in 24 hours, so 360° ÷ 24 = 15° per hour, or 1° per 4 minutes. It revolves around the Sun in about 365¼ days on an axis tilted about 23.5°, giving seasons, solstices (about 21 June and 22 December) and equinoxes (about 21 March and 23 September). Latitude is measured from the Equator, longitude from the Greenwich prime meridian (adopted 1884). Indian Standard Time is fixed on 82°30'E: 82.5 × 4 = 330 minutes, so UTC+5:30.
IATA areas, sub-areas and sub-regions. IATA splits the world into three Traffic Conference areas. Area 1 (TC1) is the Americas, the Caribbean, Greenland and Hawaii, with sub-areas North America, Central America, South America and the Caribbean. Area 2 (TC2) is Europe, Africa and the Middle East, with Iran; its Europe sub-area includes Algeria, Morocco, Tunisia and Turkey; its Middle East sub-area includes Egypt and Sudan, and its Africa sub-area splits into sub-regions such as Eastern and Southern Africa. Area 3 (TC3) is Asia and the Pacific, with sub-areas South Asian Subcontinent (India, Pakistan, Afghanistan and neighbours), South East Asia, South West Pacific and Japan/Korea.
IATA city, airport and airline codes. IATA gives three-letter codes to cities and airports: DEL, BOM (Bombay), MAA (Madras), CCU (Calcutta) and COK (Cochin). A city code can cover several airports: LON covers LHR and LGW and NYC covers JFK and EWR. Airlines get two-character designators, which may include a digit: AI (Air India), 6E (IndiGo), BA and EK. ICAO uses four-letter airport codes (VIDP Delhi, VABB Mumbai, EGLL Heathrow) and three-letter airline codes.
International Date Line, time zones, GMT and DST. The International Date Line follows the 180° meridian but bends around island groups. Crossing it westward adds a day to the date; crossing eastward subtracts one. Offsets run from UTC−12 to UTC+14, with half-hours (India +5:30, Afghanistan +4:30) and quarter-hours (Nepal +5:45). GMT is mean solar time at Greenwich; UTC, its atomic successor, is treated as equal. Daylight Saving Time (clocks one hour ahead in summer) runs in the EU from the last Sunday of March to the last Sunday of October, and in the USA from the second Sunday of March to the first Sunday of November; India does not use it (as of 2026-10).
Local, flying, ground and elapsed time. Local time from longitude: add 4 minutes per degree east of Greenwich and subtract per degree west. Timetables print local times, so convert each to UTC first. Flying time is UTC arrival minus UTC departure for one sector. Ground (grounding) time is the halt at an intermediate airport, read in one zone. Elapsed time is total origin-to-destination time, the sum of all flying and ground times.
World climate and vegetation. North America runs from tundra and taiga through prairies to Mediterranean California. Central America and the Caribbean are tropical, with Atlantic hurricanes from June to November. South America has the Amazon selvas, Llanos savanna, Pampas and the Atacama Desert. Europe has the Mediterranean climate (hot dry summers, wet winters), a west coast warmed by the North Atlantic Drift, and Alpine snow. Africa has Congo rainforest, East African savanna (safaris), the Sahara and Kalahari, and the veld. Asia has the monsoon lands, taiga, steppes and the Gobi; Australia has a desert interior, a tropical north and the Downs.
Elements of weather and climate and tourism. Weather is the short-term state of the atmosphere; climate is the long-term average, conventionally 30 years. Its elements are temperature, pressure, wind, humidity, precipitation, cloud and sunshine. Climate is both resource (sun, snow) and constraint (floods, cyclones, fog), and sets seasonality. Mieczkowski's Tourism Climatic Index (1985) rates climate for sightseeing; Gray (1970) separates sun-lust from wander-lust.
Climate and vegetation of India. IMD seasons are winter (January–February), hot weather (March–May), south-west monsoon (June–September) and post-monsoon (October–December). The monsoon reaches Kerala about 1 June; the Coromandel coast gets most rain in October–December. Mawsynram (Meghalaya) is among the world's wettest places. Tropical evergreen forest needs over 200 cm of rain (Western Ghats, North-East), tropical deciduous forest, the most widespread, 70–200 cm, and thorn forest under 70 cm. Montane and mangrove forests (the Sundarbans) complete the set.
Physical geography of India. The Himalaya has three parallel ranges: Himadri, Himachal and Shiwalik. The Northern Plains show bhabar, terai, bhangar (old alluvium) and khadar (new alluvium). Himalayan rivers are perennial; peninsular rivers are rain-fed. The Mahanadi, Godavari (longest peninsular river), Krishna and Kaveri flow east into deltas; the Narmada and Tapi flow west through rift valleys into estuaries. The Deccan Plateau lies south of the Narmada; Anamudi (2,695 m) tops the Western Ghats. The west coast (Konkan, Malabar) is narrow; the east coast (Northern Circars, Coromandel) is wide. Chilika is the largest brackish lagoon, Wular the largest freshwater lake, Sambhar the largest inland salt lake and Loktak holds the floating Keibul Lamjao park. The Thar is a hot desert; Ladakh and Spiti are cold deserts.
Tourist movement. Demand and origin factors are disposable income, paid leave, education, urbanisation, age, exchange rates and visa rules. Destination and resource factors are attractions, accessibility, accommodation, image, price and safety. Current trends are Asia-Pacific source-market growth, low-cost carriers, mobile booking, wellness and medical travel, and overtourism concerns.
Environment and forest law, EIA, EIS, EMS and carrying capacity. The Environment (Protection) Act 1986, passed after Bhopal, is the umbrella law; its Rules (1986) set standards. The EIA Notification 2006 (replacing 1994) sorts projects into Category A (central) or B (state) and runs screening, scoping, public consultation and appraisal. Coastal Regulation Zone notifications (1991, 2011, 2019) govern beach building. The Environmental Information System (ENVIS) network gathers environmental data. ISO 14001 (first issued 1996) sets an Environmental Management System on Plan-Do-Check-Act lines. Carrying capacity is physical, ecological, social or economic. The Indian Forest Act 1927 creates reserved and protected forests. The Forest (Conservation) Act 1980 requires central approval to divert forest land; in 2023 it was renamed the Van (Sanrakshan Evam Samvardhan) Adhiniyam (as of 2026-10). The Wild Life (Protection) Act 1972 provides national parks and sanctuaries.
Worked example
Flying, ground and elapsed time. On 15 July a traveller flies Mumbai (BOM, UTC+5:30) to Dubai (DXB, UTC+4), then Dubai to New York (JFK, UTC−4 under DST). Departs BOM 04:30, arrives DXB 06:05; departs DXB 08:35, arrives JFK 14:50. All times are local.
Method 1: convert every time to UTC.
| Event | Local time | Offset | UTC |
|---|---|---|---|
| Depart BOM | 04:30, 15 Jul | +5:30 | 23:00, 14 Jul |
| Arrive DXB | 06:05, 15 Jul | +4:00 | 02:05, 15 Jul |
| Depart DXB | 08:35, 15 Jul | +4:00 | 04:35, 15 Jul |
| Arrive JFK | 14:50, 15 Jul | −4:00 | 18:50, 15 Jul |
Sector 1 flying time = 02:05 − 23:00 (previous day) = 3 h 05 min. Ground time at DXB = 08:35 − 06:05 = 2 h 30 min. Sector 2 flying time = 18:50 − 04:35 = 14 h 15 min. Elapsed time = 23:00 on 14 July to 18:50 on 15 July = 19 h 50 min; check: 3:05 + 2:30 + 14:15 = 19:50.
Method 2: work in Mumbai time (IST). Dubai is 1 h 30 min behind, so 06:05 and 08:35 become 07:35 and 10:05 IST. New York is 9 h 30 min behind (5:30 + 4:00), so 14:50 becomes 00:20 IST on 16 July. Sector 1: 04:30 to 07:35 = 3 h 05 min; ground: 07:35 to 10:05 = 2 h 30 min; sector 2: 10:05 to 00:20 = 14 h 15 min; elapsed: 04:30 to 00:20 next day = 19 h 50 min. Both methods agree.
Common traps
- IATA geography: Egypt and Sudan are Middle East and Morocco is Europe (both TC2); Hawaii is TC1; Pakistan is TC3 but Iran TC2.
- City versus airport code: LON is a city, LHR an airport; IATA uses three letters, ICAO four.
- Date Line direction: westward adds a day, eastward subtracts one.
- Subtracting local times directly instead of UTC times; and forgetting that elapsed time includes ground time.
- Applying DST to India, or forgetting it in summer: New York is UTC−5 in winter, UTC−4 in summer.
- Narmada and Tapi form estuaries, not deltas; Wular is freshwater, Chilika brackish and Sambhar saline.
Speed technique
- Write one UTC column first; each sector, halt and journey is then one subtraction.
- 15° = 1 hour and 1° = 4 minutes; east is ahead (add), west is behind (subtract).
- Offset gap: same sign, subtract magnitudes; opposite signs, add them (IST +5:30 and EDT −4 differ by 9 h 30 min).
- IATA in one line: 1 = Americas, 2 = Europe–Africa–Middle East, 3 = Asia–Pacific.

In IATA's traffic-conference geography, Egypt is placed in the:
Show the answer and worked solution
Answer: option A
IATA Area 2 (TC2) covers Europe, Africa and the Middle East, including Iran, and is divided into Europe, Middle East and Africa sub-areas.
Although Egypt is on the African continent, IATA places it, together with Sudan, in the Middle East sub-area; Morocco, Algeria and Tunisia are in the Europe sub-area.
So Egypt sits in the Middle East sub-area of Area 2, option A.
It is 20:00 on 31 December in New York (UTC−5). What is the time in Kolkata (UTC+5:30) at that moment?
Show the answer and worked solution
Answer: option B
Convert to UTC first: 20:00 in New York + 5 h = 01:00 UTC on 1 January, and 01:00 + 5 h 30 min = 06:30 in Kolkata on 1 January.
As a check, the offsets have opposite signs, so the gap is 5:00 + 5:30 = 10 h 30 min, and 20:00 + 10:30 = 30:30, which is 06:30 on the next day.
So it is 06:30 on 1 January in Kolkata, option B.
If a country fixes its standard meridian at 97°30'E, what will its standard time be relative to UTC?
Show the answer and worked solution
Answer: option C
Each degree of longitude equals 4 minutes, so 97°30' = 97.5° gives 97.5 × 4 = 390 minutes = 6 h 30 min ahead of UTC.
Checking by hours, 97.5 ÷ 15 = 6.5 hours, which is again 6 h 30 min, the same way India's 82°30'E gives UTC+5:30.
So the standard time is UTC+6:30, option C.
A traveller flies Kolkata (UTC+5:30) to Bangkok (UTC+7), then Bangkok to Sydney (UTC+10). She departs Kolkata at 00:30 and arrives in Bangkok at 04:45; she departs Bangkok at 07:15 and arrives in Sydney at 18:45, all on the same date and all in local time. What is the total elapsed journey time?
Show the answer and worked solution
Answer: option C
In UTC: depart Kolkata 19:00 (previous day), arrive Bangkok 21:45, depart Bangkok 00:15, arrive Sydney 08:45; so sector 1 = 2 h 45 min, ground time = 2 h 30 min and sector 2 = 8 h 30 min.
Elapsed time = 19:00 to 08:45 next day = 13 h 45 min, and the parts check: 2:45 + 2:30 + 8:30 = 13:45.
In Kolkata time as a second check, Bangkok is 1 h 30 min ahead and Sydney 4 h 30 min ahead, so the journey runs from 00:30 to 14:15, again 13 h 45 min.
So the total elapsed time from Kolkata to Sydney is 13 h 45 min, option C.
A flight leaves Auckland (UTC+12) at 21:00 on 14 May and flies for 9 hours to Honolulu (UTC−10), crossing the International Date Line eastward. What is the local time and day of arrival in Honolulu?
Show the answer and worked solution
Answer: option B
In UTC, departure is 21:00 − 12 h = 09:00 on 14 May, arrival is 09:00 + 9 h = 18:00 on 14 May, and Honolulu local time is 18:00 − 10 h = 08:00 on 14 May.
As a check, arrival in Auckland time is 21:00 + 9 h = 06:00 on 15 May, and Honolulu is 22 hours behind (12 + 10), so 06:00 on 15 May − 22 h = 08:00 on 14 May.
So the flight lands in Honolulu at 08:00 on 14 May, option B.
