SDSS 2022: Session 5: Leveraging KnowWhereGraph for Geospatial Data Acquisition
Channel: Spatial Data Science Symposium
Date: 01/05/2023

Recorded during the Spatial Data Science Symposium (SDSS 2022), September 22-23, 2022, online

Organizers: Thomas Thelen, Zhining Gu & Meilin Shi
September 23

Description: In this tutorial, we present a workflow for using KnowWhereGraph to discover and download geospatial data. The key areas of focus are 
1. Finding data using the Knowledge Explorer 
2. Downloading the data by using the schema to write SPARQL queries 
3. Visualizing the data with geopandas 

The presentation takes the form of a hybrid slide and live presentation. Higher level information such as the KnowWhereGraph overview and session information is done on slides while more interactive segments like exploring data are live. 

The presentation is driven by the use case of wanting to visualize wildfire, road, and features of interest in Santa Barbara County. The Knowledge explorer is used to confirm that KWG has relevant data and to give a general idea on the amount of data that exists. Next, the KWG schema is used to query the database for the fires in a Jupyter notebook. The notebook is then extended to show how we can plot the data with Python.
 
By the end of the session, users will be able to take an idea or question and effectively obtain data for their downstream analysis.
