In this chapter, you learned how to use spatial queries to perform geoprocessing tasks. You also learned how to map and chart the results of your queries using ipyleaflet and data frames. You learned how to modify the maps and queries using interactive widgets in Jupyter. Lastly, you learned about how triggers work, and were shown a quick example of data checking using trigger. 

In the next chapter, you will learn how to perform geoprocessing tasks using QGIS. You will learn how to use toolboxes that are already included in QGIS. You will learn how to write your own toolboxes that you can use and share with other QGIS users, and you will learn how to use QGIS to map the results. The results can be saved as a QGIS project, or as one of many spatial data formats from QGIS.
