# Merging Maps Manually
Use this option when your maps do not have sufficient overlap for auto alignment and you are unable to visit the actual location to perform mobile-based merging.
Manual alignment lets you select two maps and merge them using visual geometry hints, think of it like assembling Lego pieces using individual 3D scans. You visually position and orient each map relative to the other based on recognizable spatial features in the 3D point clouds.

## 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://multiset.gitbook.io/multiset/basics/mapset-multiple-maps/merging-maps-manually.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.
