Week 6: Exploring and Manipulating Spatial Data
This week's assignment focused on exploring and manipulating spatial data. We created a new geodatabase via our script and then populated it with feature classes created from existing shapefiles. Then we were introduced to cursors. We created a SearchCursor along with a snippet of SQL to find the cities that are county seats in the cities feature class. Finally, we populated a dictionary with city:population key:value pairs derived from our county seat query.
All and all a pretty straightforward lab. The only thing that really hung me up was forgetting to delete the cursor (which locked the gdb and caused me to wonder why my env.overwriteOutput=True wasn't working).
