Uploading Files
You can upload files to JMap Cloud to later use them to create spatial data sources. The Files tab in the Spatial data Sources section provides functionality for uploading and managing files.
Data from the files you upload is stored in JMap Cloud databases. Files in the Files table are automatically deleted after a period of 10 days.
Files tab
This tab shows a table of files you have uploaded. A button allows you to upload new files.
The table contains the file name, file data type (vector or raster), format (CSV, KML, DXF, DWG, SHP, TAB, GeoPackage, FileGeoDatabase, GeoJSON, GeoTIFF), size, status and the date of upload. Multiple files can have the same name.
You can select one or more files in the table by checking them and the Delete function becomes available. This allows you to delete multiple files at once.
Uploading a new file
Since a vector spatial dataset typically consists of multiple files, you must combine them into a single file in compressed .zip format.
Compression is not necessary for uploading raster data files, unless you want to upload multiple files that will make up a mosaic, in which case you must combine them into a single .zip format file.
Drag and drop one or more files to upload directly into the board. The upload begins automatically.
OR
Click on Upload file to open the file explorer.
Select the files to upload. The upload begins automatically.
Up to three files are loaded simultaneously.
The maximum file size that can be uploaded is 15 GB.
In both cases, the files are displayed in the table and messages indicate the upload progress.
Status of a file
The status of each file indicates which step of the process was completed by JMap Cloud.
Waiting | The file is waiting to be uploaded. |
Processing | The file is being analyzed. |
Analyzed | The file has been analyzed by JMap Cloud which identifies properties such as file type, CRS, attributes, etc. It is available to create a spatial data source. |
Uploading | The file is being uploaded. A line in the Status column indicates the progress of the upload. A circle in the header bar indicates the progress of the upload as well as the number of files being uploaded. A message indicates whether the uploadt a été effectué avec succès ou s'il y a eu un échec. |
Uploaded | The file has been uploaded. It needs to be analyzed to be available for creating a spatial data source. |
Error | There is an error in the file loading process. |
Managing a file
Like other resources, to manage a file:
Create a spatial data source
Click on Create source. This function is available when the file status is Analyzed. The interface for creating a data source opens.
Enter the information to create the data source. Details are offered in the Data Files section.
Click on Create. The data source is created and displayed in the table on the Data Sources tab.
Pause upload
This function is available when the file is being uploaded or analyzed and allows you to stop the current process.
Display information
Click on Display informations. The interface displays the following information: file name, size, format, status, user ID of the user who uploaded it, date and time of upload and metadata. Metadata includes in addition to the above information, the unique identifier of the file, organization and task; the name of the data layers, the name and type of each attribute, the number of elements.
Delete a file
Click on Delete. A message asks you to validate your choice.
The deleted file disappears from the table. The spatial data source created from the file is not affected.
