automate_gis_python

Goal:

• Automating repetivte workflow tasks as my time as a GIS Data Analyst.
  • Apply Buffers and clips ot data as it comes in
  • Using network analyst to expand ways to find critcal service areas.

Before Time to Complete Analyis: Per State 30 hours each time a new model and map needed to be made as a manual process. After Time to Compelte Analysis: Programatically - 2 Hours to Run on Computer with similar large datasets with no

Logic Design:

• 1. Select Analysis --> 2. Loop through Buffer and Clip Analysis --> 3. Network Analyst for Service Area and Nearest Faclity

1. Using select_analysis in arcpy utilizing SQL within the python script to extract counties and specific attributes.

• can be easily edited to use a lookup list or dictonary whenever the data becomes larger.

2.1 Create Lists and Loops for Clip and Buffer

• One example of lists and loops used in the script
• Double for loop to clip each feature to each countya nd rename with clip + int

2.2 Setting up Features for Network Analyst Function

• Clipping hospitals, roads, and abulance dispatch points for a specfic county layer

3. Building and solving Network

• 1 manual stpe of creating the road network a short coming of ArcGIS
• Created service areas based on 2000 meter increments
• Created Closet Hospital routes using length
