Question

What is a Query in spatial data analysis?

Hint:

Queries help filter data to answer specific spatial or attribute questions.

Answer 1

In GIS and spatial data analysis, a Query is a request or operation to extract specific information from a dataset based on defined criteria.
Queries help users search, filter, and retrieve data that meets particular conditions — for example, selecting all parcels larger than 1 hectare or roads within 500 meters of a river.
Queries can be attribute-based (using database fields) or spatial (based on location or spatial relationships).
They are essential for data exploration, analysis, and decision-making because they allow analysts to isolate relevant subsets of large datasets.
Therefore, a Query is an essential tool for extracting meaningful information from GIS data.
