Click to open the search field. 2. Enter the information for the place you are looking for (address, postal code, city, place name, etc.). JMap NG uses the Mapbox Geocoding service to find the place. Matching results appear as you type. 3. Select the desired place by clicking it in the list. The map automatically centers on that place, identified by a marker , and zooms in to show more details. A tooltip displays information about the place.\ **Note:** When you search for a new place, the marker from the previous place disappears.
4. Click to erase the search terms. 5. Click to close the search and remove the information from the last displayed place. ## Map Navigation Tools These tools are available in the JMap NG graphical interface.
IconFunction
Displays the map scale and the cursor coordinates (latitude and longitude). You can change the scale or center the map on precise coordinates.
Displays the initial map extent. If no initial extent has been defined for the project, the map displays the entire planet.
Displays the last position viewed on the map.
Resets the map to its original orientation.
Displays your current position on the map (blinking point). Click again to hide geolocation.
Note: You must allow JMap NG to access your device's location.
The scale indicates the actual distance on the ground corresponding to the line shown on the map. This distance updates automatically when you zoom in or out. The distance unit corresponds to the one selected in the user Profile and Settings panel.
## Navigating with Your Fingers or Mouse You can explore the map interactively. ### With your fingers (touch device) * **Pinch/spread**: Zoom out / zoom in * **Drag**: Move the map * **Two-finger rotation**: Rotate the map * **Two-finger drag up/down**: Tilt the map (3D navigation) ### With your mouse * **Scroll wheel**: Zoom in / zoom out * **Left click + drag**: Move the map * **Ctrl + click + drag**: Rotate and tilt the map ### Controlling Orientation 1. Click to display information about the rotation (in degrees relative to North) and tilt (in degrees relative to the horizontal plane). 2. Click to restore the default orientation (flat view facing North). The icon turns grey and indicates North on the horizontal plane.
## Centering the Map on Coordinates and Changing the Scale You can center the map on a precise coordinate and change the map scale. ### Changing the Scale 1. Click to open the geographic information window. 2. Click **Scale** to open the **Change Map Scale** window. 3. Enter the new scale or adjust it with the arrows. The map scale updates in real time. 4. Click **OK** to close the window and apply the chosen scale. ### Changing the Coordinate System Click **EPSG:4326** or **EPSG:3857** to switch between reference systems: * **EPSG:4326**: Coordinates in Latitude and Longitude (Lat, Lon) * **EPSG:3857**: Coordinates in X (Longitude) and Y (Latitude) in meters (standard system for web mapping applications) The displayed coordinates correspond to the current cursor position and update as you move it.
### Centering on Precise Coordinates 1. Click the displayed coordinates to open the **Recenter Map** window. 2. Enter the desired coordinates or adjust them with the arrows. The map automatically recenters and a point indicates the exact position. 3. Click **OK** to close the window. You can click to return to the previous view. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.jmapcloud.io/en/jmap-ng/jmap-ng-user-guide/introduction/navigating-the-map.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
