Question 11: You are working on an economic development map, using GIS. You identify areas that meet each of the following requirements:

-Less than 5 km from a highway

-Less than 2 km from a railway

-On ground with a slope less than 5 degrees.

What is the name given to the GIS operation of combining all these maps, to identify areas that areas that simultaneously meet all these requirements?

A-

Solar orbit

B-

Remote sensing

C-

Overlay operation

D-

Line operation

Question 12: A "multispectral" image means that the image is:

Question 13: Urban areas typically warmer than rural areas because urban areas typically have…

A-

More trees.

B-

Vertical surfaces, dark surfaces, high heat capacity, and low evaporation.

C-

More vehicles.

D

More people.

E-

A-

Solar orbit

B-

Remote sensing

C-

Overlay operation

D-

Line operation

Explanation / Answer

11-C- Overlay operation ( Here we superimpose the different data sets or maps of different themes)

12-C- An image of different wavelengths ( Multispectal means there are multiple bands of wavelength in which remote sensing data can be acquired)

13-C- More vehicles ( There is an effect called UHI, Urban Heat Island by which an urban area gets warmer than rural area due to heat generated by cars, buses, rails etc)
