When selecting city points within a country polygon, which spatial query should be used starting with a selected country polygon?

The correct choice involves using a spatial query that identifies city points located within the defined boundaries of the selected country polygon. This query effectively retrieves all city features that are spatially related to the country, particularly those that intersect with it.

Using a query that selects city points that intersect with the country polygon ensures that you are focusing on the relevant data—specifically, the points that fall within the area of interest described by the polygon. This is crucial in many spatial analysis situations, where understanding the relationship between different geospatial features is necessary for tasks such as urban planning, resource management, or demographic studies.

In this case, the spatial relationship defined is one of intersection, which is the ideal choice when you're starting with a specific polygon (in this case, the country) and want to determine which points (the cities) are related to that polygon.
