Fetch the MOM file for an Indoor Map through Platform UI.

A. Application credentials

Access to your data is possible via the platform applications in your Indoor Maps project. Each application can have two sets of OAuth2 credentials, which authorize access. To get the OAuth2 KEY ID and KEY SECRET for the Default Map Collection App, follow these steps:

1. Sign in to the HERE platform using your HERE account.
2. Open the Access Manager from the launcher.
3. Select the Apps tab.
4. Select Show all apps and locate the Default Map Collection App.

1. Create the OAuth2 credentials for this App. You must be an Org Admin with management rights enabled for all apps and resources. Note that you need to download the credentials and store them in a safe place, the platform portal will not allow you to re-download credentials.

The OAuth2 credentials are taken into use as instructed in the section OLP CLI Configuration.

You can also create your own application for this purpose. The application must have a read access to the main maps catalog.

B. Fetch indoor maps from the Versioned Layer using the platform UI

To fetch the MOM file, follow the steps.

1. Sign in to the HERE platform using your HERE account.
2. Navigate to the Data tab from the Launcher as shown in the image.



3. Search for “-maps” or select Indoor maps: Indoor maps catalog.



4. Select the Indoor Map Models versioned layer.



5. Navigate to Inspect tab. Click on the desired Partition ID to download the raw data. Please note, when accessing a single indoor map, you must have the Indoor Map UUID, which you can obtain from the Indoor portal and is also highlighted as a part of partition ID.



Note that the indoor map data is Gzip compressed so you will have to un-compress first.
