Vector/Raster Data Files

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.

Files can be uploaded during the SDS creation process or uploaded in advance to JMap Cloud’s storage area. For more information, refer to the Uploading Files section.

Multiple Files and Continuous Maps

An SDS can include several vector or raster data files to form a seamless map. For instance, in CAD workflows, it is common to divide a territory into rectangular tiles. When all these files are read together, JMap Cloud can reconstruct a continuous map—as long as they share the same data structure (geometry, layers, and attribute types). In such cases, all files must be packaged into a single .zip archive.

Creating an SDS from Vector Files

1. Upload the files to JMap Cloud

2. Metadata analysis

3. Validation and configuration of SDS parameters

4. Once completed, the data and its configuration are stored in JMap Cloud’s databases.

Creating an SDS from Raster Files

1. Upload the raster file to JMap Cloud

2. The system analyzes and validates its characteristics

3. During SDS creation, the following processes are automatically applied:

   • Reprojection to EPSG:3857 coordinate system

   • Conversion to the optimized COG (Cloud Optimized GeoTIFF) format

   • Creation of a multi-resolution image pyramid for efficient display

The final image is optimized for fast navigation and stored in JMap Cloud.

Creating a SDS from files

Creating an SDS from Files

1. Go to the Data Sources tab and click Create a data source.

2. Select Vector/Raster data file.

3. Choose between:

   • New File: to upload a file from your device.

   • Existing File: to select a file already uploaded to JMap Cloud. See Uploading Files for more information.

For vector datasets, you must combine all associated files into a single .zip file before uploading.

For raster datasets, compression is not required unless you are uploading multiple files to create a mosaic—in which case they must also be combined into a .zip archive.

Configuring SDS Parameters

• If uploading a new file, JMap Cloud automatically analyzes the file’s metadata (format, type, coordinate system, geographic extent, etc.) before displaying the configuration window.

• If selecting an existing file, the analysis (and conversion, in the case of raster files) has already been completed, and the configuration window is shown immediately.

The configuration parameters vary depending on the data type and format. See the File Settings section for detailed information.

You can also add a description and tags to help filter and organize your data sources. To create new tags, simply enter text in the Tags field.

Finalizing the SDS

Click Create to finalize the SDS. It will appear in the data source table. Its status will show as In Preparation during processing, then Ready once the creation is complete.

Files uploaded during SDS creation are listed in the Files tab. These files are automatically deleted from JMap Cloud after 10 days.

File settings

The table shows the general settings to configure when creating a DS from vector/raster data files.

Name	Give the DS a name. There are no restrictions for the name of resources (DS, projects, map layers) in JMap Cloud.
Layer	Vector data only. This setting is specific to files that contain multiple data layers (GML, DWG, GeoJSON, etc.). Select the layer from which you are creating the SDS.
CRS	If JMap Cloud has correctly identified the CRS, this field cannot be modified. Otherwise, select the data projection system.
X	Vector data only. This setting is specific to CSV format files. Select the field (numeric values) that contains the latitude coordinates.
Y	Vector data only. This setting is specific to CSV format files. Select the field (numeric values) that contains the longitude coordinates.
Unique identifier	Optional. Vector data only. Select the field that contains the unique identifier of each map element. 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 (DS, projects, layers).

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