# MapSet (Multiple maps)
Localization explanation in MapSet
To localize a user on a specific mapSet, provide the MapSet Code where the user is located. Retrieve the mapSetID by logging into the Developer Portal or using our REST API
In the Map Localization Manager in Unity SDK, select Localization Type as "Mapset" and then past your mapSetID
### Add MapSet Mesh in Unity to visualize your Mesh
Download the combined Mesh from the developer portal and add it in Unity SDK to visualize your maps
### Update MapSet Code in Runtime
To dynamically change the mapOrMapsetCode at runtime in your existing script, you can create a UI input field or a method that updates the mapOrMapsetCode in the MapLocalizationManager. Below is an example script showcasing how to do this via a simple button press or direct method call.
```csharp
using MultiSet;
using UnityEngine;
using UnityEngine.UI;
public class MapSetCodeUpdater : MonoBehaviour
{
// Reference to the Map Localization Manager
private MapLocalizationManager mapLocalizationManager;
// Input field to get the new Map ID from the user
[SerializeField]
private InputField mapCodeInputField;
void Start()
{
// Find the Map Localization Manager component in the scene
mapLocalizationManager = FindObjectOfType();
if (mapLocalizationManager == null)
{
Debug.LogError("MapLocalizationManager not found! Please ensure it is added to the scene.");
}
if (mapCodeInputField == null)
{
Debug.LogError("InputField reference is missing! Please assign it in the inspector.");
}
mapLocalizationManager.localizationType = LocalizationType.Mapset;
}
// Method to update the Map ID
public void UpdateMapId()
{
if (mapLocalizationManager != null && mapCodeInputField != null)
{
string newMapCode = mapCodeInputField.text;
if (!string.IsNullOrWhiteSpace(newMapCode))
{
mapLocalizationManager.mapOrMapsetCode = newMapCode;
Debug.Log($"Map Code updated to: {newMapCode}");
}
else
{
Debug.LogWarning("Map Code cannot be empty! Please enter a valid Code.");
}
}
}
}
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.multiset.ai/unity-sdk/ar-foundation/on-cloud-localization/mapset-multiple-maps.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
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.
