Description

This Standard Choice sets various limits on the Nearby Query functionality, for example, the maximum number of features that users can select to perform a nearby query. Proper limits can prevent performance issues when users select too many GIS objects or meaningless data to perform a nearby query.

Civic Platform has set default limits but you can use this Standard Choice to change the limits according to your agency’s specific requirements.
