Locate
In GIS work, "locating" usually means placing a known position on the map quickly and moving the map view near that position for viewing, checking, and follow-up operations.
The Locate feature in iXGIS is essentially a coordinate positioning tool. It lets you enter longitude and latitude coordinates, or pick a location directly on the map, then pans the map to the target point and displays the address information for that point.
This address information is not entered manually. It is retrieved with reference to the Tianditu reverse geocoding service. Reverse geocoding means converting a longitude and latitude coordinate into a readable address description, such as a city, district, road, and house number, or a location near a road or a certain distance northeast of a POI.
Therefore, the Locate feature in iXGIS does two things:
- Moves the map to a specified coordinate.
- Converts the coordinate into a readable address to help users understand the current location.
