Feature Description

Location analysis is an interactive query based on distance analysis principles, which can calculate the distance from a point to lines or regions. The calculation results will be displayed in both the Location Analysis dialog and the map.

As an interactive query function, location analysis requires the map window to be open before use.

Application Scenarios

During navigation, it's necessary to query the shortest distance from a ship's position to the coast or islands.
