PyGeoWeaver is a Python package that provides a convenient and user-friendly interface to interact with GeoWeaver, a powerful geospatial data processing application written in Java. With PyGeoWeaver, Jupyter notebook and JupyterLab users can seamlessly integrate and utilize the capabilities of GeoWeaver within their Python workflows.

Installation

To install PyGeoWeaver, ensure you have Python 3.7 or later installed. You can then install PyGeoWeaver using pip:

pip install pygeoweaver

Startup

To start using PyGeoWeaver, you can launch the GeoWeaver graphical user interface by executing the following command in a Jupyter notebook cell:

import geoweaver
geoweaver.start()

Alternatively, you can start GeoWeaver directly from the terminal:

gw start

Options and Help Text

PyGeoWeaver provides several commands to interact with GeoWeaver. Below is a list of available options and their descriptions:

• Launching GeoWeaver GUI: Opens the GeoWeaver interface.

  geoweaver.start()
  

  or

  </code></pre>
  </li>
  </ul>

  <pre><code>
  - **Stopping GeoWeaver**: Stops the GeoWeaver interface.
  ```python
  geoweaver.stop()
  

  or

  gw stop
  

  • Listing Existing Objects: Lists hosts, processes, and workflows.

    geoweaver.list_hosts()
    geoweaver.list_processes()

  • Importing a Workflow: Imports a workflow from a ZIP file.

    geoweaver.import_workflow("<workflow_zip_file_path>")
    

  • Viewing Workflow and Process History: Retrieves the history of a workflow or process run.

    geoweaver.get_workflow_history("<workflow_history_id>")
    geoweaver.get_process_history("<process_history_id>")
    

  • Inspecting Process Source Code: Views the source code of a process.

    geoweaver.detail_process("<process_id>")
