Correct option is A
Geographic Information System (GIS) is the
core analytical tool in precision agriculture that handles
spatial data.
It allows for
data storage,
retrieval, and
conversion of various forms of information into
spatial (map-based) data.
GIS enables farmers to analyze field variability and make site-specific decisions on irrigation, fertilization, and crop management.
Explanation:
(a) GIS (Global Information System) –
Correct answer. Specializes in
mapping, storing, and analyzing spatial data used in agriculture.
(b) GPS (Global Positioning System) – Provides
location data, but does not handle spatial data analysis.
(c) DSS (Decision Support System) – Helps in
decision-making using data models but is not specifically designed for spatial data transformation.
(d) VRT (Variable Rate Technology) – Uses data from GIS and GPS to
apply inputs variably, not responsible for data analysis or storage.
