Module 7: Explore/Manipulate Spatial Data

This week we will studied various approaches to exploring and manipulating spatial data. Specifically, we looked at list functions and how they can be used, built-in Python functions, the ArcPy data access module arcpy.da, cursors, and were also introduced to tuples and dictionaries.  This week we explored: 

• how to check for and describe data with arcpy.Describe, 
• how to manipulate list of data by indexing, delete, sort and append
• how to create an empty dictionary {}, and add, change and delete
• how to work with search cursors to iterate over data stored in lists 

We learned the benefit of working with dictionaries to obtain our data for the above script. We also used a search cursor with SQL expression and added those results to an empty dictionary.
