# Map View Coordinate Picking

Once a borehole has coordinates and a coordinate system, GeoDin can display it on a map and let you adjust the location interactively. The map view also supports the reverse workflow - clicking on the map to capture coordinates into a new or existing object.

For configuring the coordinate system itself (EPSG codes, the `G1_EPSG.GSD` dictionary, and in-mask transformations), see [Coordinate Systems and EPSG](/maps/coordinate-systems-and-epsg.md).

## Displaying a borehole on the map

Once coordinates and a coordinate system are entered, a borehole can be displayed on a map via the **map preview** button in the right-hand ribbon.

## Picking coordinates by clicking

The map view supports picking coordinates by clicking. The **Draw** tool lets users click on the map to capture local easting / northing values back into the coordinate fields. This is useful for establishing **tentative borehole locations** before precise survey data is available.

The **Cross-section** method also includes a top-down map view for spatially selecting boreholes - use drag-rectangle selection to pull all objects in an area into the cross-section workflow.

# 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. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.geodin.com/maps/map-view-coordinate-picking.md?ask=<question>&goal=<endgoal>
```

`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.
