Code, Data and Analysis regarding Crime & Intelligence Analysis, some data may be from my hometown of Indianapolis, and others may be of other publicly available sources.

• /data: Data files such as incidents or extracted data from GIS ready to be moved into other applications such as Excel
• /examples: Example analyses done
• /scripts: Any scripts used, currently there is a Python script for extracting the incident report data from CityProtect
• /shapefiles: Shapefiles used or created in GIS software
• /visuals: Charts and images that may be used in the example analyses files
• impd_analysis.qgz: My QGIS project file used for the stuff in this repo
• Resources.md: Helpful links that I have found that I am saving for anyone else that is curious

As a public citizen, I do not have access to the same level of information as actual city or public safety employees. For public use, IMPD stores crime data in CityProtect. There is a way to download bulk data from CityProtect natevely, however it misses the crucial lat & lng coordinates we need for importing into GIS software. I wrote a custom python script to use the same API the CityProtect app does to display incidents on its map.

• Run the ./scripts/impd_incidents_retrieval.py script. Modify the begin and end dates as needed.

I use QGIS because it is free and open source. Once the data is gathered, do the following:

• Ensure CRS is set to WGS 84 (EPSG:4326)
• Download police beats shapefile from https://data.indy.gov/datasets/indypolicebeats/explore and import
  • Beat ED51 was invalid in QGIS so I followed the guide here to fix it. I have saved the fixed shapefile in ./shapefiles
• Import the .csv from the PY script as a delimited text layer. Use Point Definition for Geometry and use lng as X and lat as Y.
  • The script includes categories so the dots can be recolored according to type, the parentIncidentType seems to be the best for categories.
  • Also, creating a spatial index for the point layer can help with analysis
