The Correct Option is B
Solution and Explanation
Concept:
A Geographical Information System (GIS) is built from several subsystems, each handling a distinct stage of working with spatial data: capture (input), storage, management, analysis and output.
Step 1:
The data capture subsystem is the very first stage. Its job is to bring spatial and attribute data into the GIS from the real world. This means acquiring data from sources such as field surveys, GPS, maps, remote sensing imagery and existing digital files.
Step 2:
Transformation, storage and retrieval are handled by other subsystems (data management and analysis subsystems). So the capture subsystem is specifically about gathering or acquiring the raw data, not processing or storing it later.
Answer: Option (2) — Acquiring Data.
