Geoprocessing with Python

Modeling is a valuable tool for creating a visual guide for sequencing geoprocessing tasks. Laying out step-by-step visuals aids in problem-solving, creates solid code, and results in tools that can help other GIS analysts.  ArcGIS Pro incorporates visualization with ModelBuilder. Even though the geoprocessing sequence can be elaborate, using ModelBuilder provides a clean, organized workspace to visualize the entire process.

We built upon our geoprocessing knowledge by writing our own Python scripts. For our assignment, we needed to create a script that would add XY coordinate points to a point shapefile of Austin area hospitals. Then the updated file needed a 1000 meter buffer with dissolve. Finally, we need the script to return a print message confirming each function was executed. The final outputs are pictured below. 

 

Creating a flowchart in ModelBuilder was a helpful way to visualize each step. The biggest challenge I had this week was copying script from various programs as the different formatting created syntax errors. The copied text was deceptive as it looked correct but was being misread by each program.
