Updating Data

You can update the data of a vector spatial data source or a non-spatial data source. This process allows you to replace the file or web service that provides data to the data source (DS).

1. Open the Update Interface

Select the Update Data function to access the interface where you can:

• upload a new file,

• select an existing file already stored in JMap Cloud,

• or, in the case of a web service, reconfigure the connection query.

If the selected file is not compatible with the existing data source, an error message will appear.

2. View and Edit Information

The interface displays the current properties of the data source:

• Name,

• Coordinate Reference System (CRS) (for spatial DS),

• Description,

• Tags.

You can keep these values as they are or update them as needed.

3. Review and Configure Attributes

The attributes of the new file are shown. You can index specific attributes to facilitate searches. Depending on the file format, some additional parameters must be completed. These are explained in the spatial data file and tabular data file sections.

A new table is created in JMap Cloud with the updated data. The previous table is automatically deleted.

4. Finalize the Update

Click Save. Once the changes are applied, the status of the data source is updated to Ready.

If the CRS of the new file is different from the one configured for the data source, the data will not be displayed on the map when using the View Information function.

5. Impact on Map Layers

The new file may differ from the original in terms of format, CRS, geometries, or attributes. In such cases, you will need to update the configuration of the map layers that use this data source.
