Non-spatial tabular data files

JMap Cloud creates data sources (DS) from CSV format files of tabular data without a spatial component. Some data can then be associated with spatial data.

Files can be uploaded when creating a data source or uploaded in advance. For more information, see the Uploading Files section.

Creating a DS from tabular data files involves uploading the file to JMap Cloud, analyzing the metadata, and validating and completing the DS parameters. When you complete the data source creation, the data and its configuration are copied to the JMap Cloud databases.

Creating a DS from tabular data files

1. On the Data sources tab, click on Create a data source.

2. Select Tabular data file (non spatial). The selection interface offers two choices: New File, to upload a data file to JMap Cloud and Existing File, to select files that are already on JMap Cloud. See Uploading Files for more information.

3. If you are creating the data source from a new file, in the New File tab select the data file to upload. Only one CSV file in .zip format can be uploaded. If you are creating the data source from files that already exist on JMap Cloud, select them in the Existing File tab.

4. Configure the DS settings. When you select a new file, before displaying the settings configuration window JMap Cloud analyzes the file's metadata in order to identify the format, the type of data it contains and other metadata. When you select an existing file, JMap Cloud has already performed this analysis and the configuration window is displayed directly. The File settings section details settings to configure.

5. Add a description of the DS and tags that may be useful for filtering data sources. You can create new labels by entering the text in the Tags field.

6. Click on Create. The new DS is displayed in the table. Its status is Preparing while the creation is completed. Subsequently the status is Ready.

The files that you upload when creating an DS are displayed in the table in the Files tab. After a period of 10 days the files are automatically deleted from JMap Cloud.

File settings

The table shows the general settings to configure when creating an DS from tabular data files.

Name	Give the SDS a name. There are no restrictions for the name of resources (SDS, projects, map layers) in JMap Cloud.
Description	Optional. You can add a description of the data source.
Unique identifier	Optional. Vector data only. Select the field that contains the unique identifier of each table register. This identifier is necessary when you want to establish links with other data sources.
Attributes	Vector data only. File attributes are presented in a table that contains the attribute name and type as well as a box to check which attributes should be indexed.
Description	Optional. You can add a description of the data source.
Tags	Optional. You can add labels that can be used to sort or filter SDS. Tags are available for use with all resources (SDS, projects, layers).
Fields	The fields in the file are presented in a table that contains the name and data type of each field.

Only indexed attributes can be used in simple searches (searching for features in layers of a project based on attribute values) of the NG map application.
