The grass.jupyter.InteractiveMap() tool offers basic map visualization features like zooming and layer addition but suffers from suboptimal rendering speed (approximately 7.55 seconds per loop) and cumbersome data integration, particularly with large datasets. Additionally, its reliance on the Pseudo-Mercator projection limits its versatility. This abstract highlights the need for enhancements to improve rendering efficiency, streamline data integration, and broaden projection support for increased usability and functionality.


Main Goals:

  1. Enhance InteractiveMap with interactive data retrieval features, enabling users to query attribute values and draw geometries directly on the map.
  2. Implement support for custom coordinate reference systems (CRS) in InteractiveMap to eliminate the need for layer reprojection and improve visualization speed.
  3. Optimize rendering processes for SeriesMap and TimeseriesMap by parallelizing map rendering using standard Python libraries like multiprocessing.

Stretch Goals:

  1. Improve integration between GRASS and Pandas for smoother data handling and analysis.
  2. Incorporate tile-based rendering to efficiently display extensive datasets without compromising performance.
  3. Integrate a graphical user interface (GUI) within a Jupyter Notebook for enhanced user experience and ease of interaction with InteractiveMap functionalities.
