Question

which technology helps in gathering spatial data for mapping?
a. gis
b. drone technology
c. atmospheric sensors
d. ice drilling
what does remote sensing typically involve?
a. fishing operations
b. physical sampling
c. data collection via satellites or aircraft
d. direct human observation

Explanation:

First Question (Which technology helps in gathering spatial data for mapping?)

• Option a (GIS): Geographic Information Systems (GIS) are used for managing, analyzing, and visualizing spatial data, but not primarily for gathering it.
• Option b (Drone technology): Drones can capture aerial imagery and spatial data for mapping purposes by flying over areas and collecting data.
• Option c (Atmospheric sensors): These are used to measure atmospheric conditions, not spatial data for mapping.
• Option d (Ice drilling): This is used for extracting ice cores, not gathering spatial data for mapping.

So the correct option is b.

• Option a (Fishing operations): Unrelated to remote sensing.
• Option b (Physical sampling): Remote sensing does not involve physical sampling; it's about collecting data from a distance.
• Option c (Data collection via satellites or aircraft): Remote sensing is the process of acquiring data about an object or area without physical contact, often using satellites or aircraft to collect data.
• Option d (Direct human observation): Remote sensing is "remote", so direct human observation is not part of it.

So the correct option is c.

Answer:

b. Drone technology
