Question

Identify the satellites used for mapping of Urban Areas. 
• [A.] GOES 
• [B.] METEOSAT 
• [C.] IKONOS 
• [D.] LANDSAT 
• [E.] PSLV-4 Choose the correct answer from the options given below:

• A. A and B only
• B. B and C only
• C. C and D only
• D. D and E only

Hint:

Important remote sensing satellites:
• IKONOS $\rightarrow$ High-resolution urban mapping
• LANDSAT $\rightarrow$ Land use and environmental studies
• GOES METEOSAT $\rightarrow$ Weather monitoring satellites PSLV is a launch vehicle developed by ISRO.

Answer 1

The Correct Option is C

Concept: Urban area mapping requires satellites capable of capturing high-resolution Earth imagery for:
• Land use mapping,
• Urban growth analysis,
• Infrastructure planning,
• Environmental monitoring,
• GIS applications. Remote sensing satellites with imaging sensors are commonly used for these purposes.

Step 1: Analyze each satellite/system listed in the question.
• A. GOES -- Primarily a meteorological satellite used for weather observation.
• B. METEOSAT -- Weather satellite mainly used for meteorological studies.
• C. IKONOS -- High-resolution Earth observation satellite used for urban mapping and GIS applications. \checkmark
• D. LANDSAT -- Earth observation satellite widely used for land use and urban mapping. \checkmark
• E. PSLV-4 -- A launch vehicle, not a mapping satellite.

Step 2: Identify the correct combination.
The satellites used for urban area mapping are: \[ C \; \text{and} \; D \] Therefore, the correct answer is: \[ {C\; \text{and}\; D\; \text{only}} \]
