You can create data sources (DS) from five types of support:

• Vector or raster data files: Various formats are supported (SHP, CSV, GML, GeoJSON, FileGeoDB, GeoPackage, DWG, TAB, GeoTIFF)

• Non-spatial tabular data files

• WMS/WMTS services

• Vector tile services

• Feature services

The Data sources tab allows you to create and manage the data sources you will use in your projects.

This section displays a table listing the data sources you own, as well as those you have permission to access. For more details on access and resource management, see the section.

Each data source appears as a row in the table. The columns provide the following information:

• Name of the data source

• Source type

• Status

• CRS (Coordinate Reference System)

Creating a Data Source

To create a new data source, click the Create a data source button. A dropdown menu will allow you to select the source type:

• Vector/Raster data file

• Tabular data file (non-spatial)

• WMS/WMTS service

• Vector tile service

The following steps will vary depending on the selected source type.

The first step in the map‑publishing workflow is to connect JMap Cloud to your data by creating data sources (DS).

A data source is any service or file that provides information to JMap Cloud, including:

• Spatial data (vector or raster)

• Non‑spatial tabular data

JMap Cloud supports several types of data sources:

You can update the data of a vector/raster spatial data source or a non-spatial data source. This process allows you to replace the file 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.

To delete a data source:

1. Select the Delete option from the DS menu.

2. A confirmation message will appear, listing any map layers or project tables that use this data source.

3. Click OK to confirm and delete the data source.

Web Map Service (WMS) and Web Map Tile Service (WMTS) are two standards defined by the Open Geospatial Consortium (OGC). They specify how applications should send requests to obtain maps from compatible servers.

WMS servers use the HTTP protocol to return map images in common raster formats such as PNG, JPEG, or GIF.

Server capabilities are described in an XML document that outlines the supported request types, available layers, supported projections, and other metadata.

WMTS servers, on the other hand, deliver maps as predefined tiles, enabling faster and more efficient rendering, particularly for large-scale navigation.

JMap Cloud can query servers that comply with either the WMS or WMTS standard to create spatial data sources, allowing you to integrate external map layers into your projects.

The settings you need to complete are as follows:

You can access several functions from a data source's menu : view its information, edit its configuration, update the data, manage permissions, or delete the source.

The following sections provide detailed descriptions of each function.

The table presents the different statuses that can have a spatial data source.

JMap Cloud allows you to create data sources (DS) from CSV files containing tabular data without spatial components. These datasets can later be linked to spatial data if needed.

Displaying Data Source Information

To view the information for a data source (DS), open the menu associated with the desired DS and select View Information. The interface consists of two tabs: Information and Attributes.

Information Tab

This tab displays general details about the data source:

• Name and description

• References: projects, layers, and/or tables using this data source

• Associated tags

For spatial DS, an interactive map is displayed:

• A dotted outline indicates the geographic extent of the DS

• The base map is provided by OpenStreetMap

• Digital Elevation Models (DEM) from GeoTIFF files are shown in grayscale

Additional technical information is also displayed:

• DS identifier (click to copy to clipboard)

• Unique identifier within JMap Cloud

• Coordinate Reference System (CRS)

• Total number of elements in the DS

For tabular DS, a navigable data table is shown, along with:

• The number of loaded rows

• The total number of records in the table

Attributes Tab

This tab lists all attributes (or fields) of the DS. For each attribute, three sections are available:

• Settings: title, data type, and indexing status for quick search

• Statistics: value statistics (depending on the attribute type)

• Value Domain: displays the current domain (if any), or allows you to create one

Value Domain

A value domain defines the valid set (finite or infinite) of values that an attribute can take—typically for text or numeric fields.

To create a value domain:

1. Click Create Value Domain. The Value and Label columns appear. All values present in the data are automatically added.

2. Click + to add a row.

3. Enter the value and its label.

4. Click to save or to cancel.

You can:

• Remove a value that is not present in the data by clicking the icon

• Delete the entire domain by clicking Delete Value Domain

Editing Parameter Values

You can modify some parameters:

1. If you have edit permissions for the DS, when you hover over the Description, Labels, and Unique identifier (SDS) parameters, the icon appears, allowing you to edit the parameter.

2. Also, if you have edit permissions, you can edit attribute/field titles, index them (by checking the box Indexed), and create, modify, or delete a value domain for text or quantitative attributes.

3. Press or to save or discard changes.

Editing Parameters

If you have editing permissions on the DS, you can modify certain parameters directly in the interface:

• Hovering over the Description, Tags, or Unique Identifier (for spatial DS) displays the icon, allowing you to make edits

• You can also:

  • Edit attribute titles

Click to save or to cancel your changes.

JMap Cloud allows you to create spatial data sources (SDS) from various vector and raster file formats: CSV, KML, DXF, DWG, SHP, TAB, GeoPackage, FileGeoDatabase, GeoJSON, and GeoTIFF.

Creating a Spatial Data Source from Files

Creating an SDS is done in several stages:

1. Selecting the file

You can upload files to JMap Cloud to use them later when creating data sources. The Files tab, located in the Data Sources section, provides tools to upload and manage your files.

The content of uploaded files is stored in JMap Cloud’s databases. However, files listed in the Files table are automatically deleted after 10 days.

Files Tab

This tab displays a table of all the files you’ve uploaded. A button is available to let you upload new files.

The table includes the following information for each file:

As the owner of a data source (DS), you can grant access permissions to other users within your organization.

Permissions can be assigned to:

• Members with the Editor or Viewer role;

• Groups;

• API keys.

Each role has different levels of access.

Granting Permissions

Permissions follow a hierarchical structure:

• Owner includes both Edit and View permissions;

• Edit automatically includes View;

• Viewer role-based permissions are at the base of the hierarchy and always include View.

Steps to grant permissions:

1. Click the icon next to a DS, then select Permissions. The permissions management interface will open, displaying:

   • the name of the DS;

   • the list of members, groups, and API keys with their current permissions.

2. To add a new user:

Modifying or Removing Permissions

You can at any time:

• change existing permissions;

• add new users;

• remove all permissions from one or more members, groups, or API keys.

Steps to manage permissions:

1. Click , then select Permissions to open the configuration interface.

2. Check or uncheck the relevant boxes to update permissions.

To remove all permissions:

• Start by unchecking the highest-level permission (e.g., Owner). The next level (e.g., Edit) becomes the highest active permission.

• For Viewer-type permissions, you must first uncheck the specific sub-permissions before removing the general View right.

To delete members, groups, or API keys from the permissions list:

• Check the box next to each name;

• Click the icon to remove them from the list.
