A quick method for writing out some rows and a subset of columns from a feature class to a CSV. This is particularly well-suited for when you're working in ArcGIS Desktop or Pro and need to quickly export some rows and a subset of columns from a vect

An example of an ETL script that allows you to query a remote spatial data source and join the query result with a CSV. For now, this requires csvs-to-sqlite as ogr2ogr doesn't seem to like working with CSVs with the SQLite dialect for SQL queries. O

Function that takes a list of shapefiles and adds them to a File Geodatabase

Function that takes a directory as a parameter and returns a list of shapefiles. Although this doesn't explicitly involve arcpy, this function could be used for automating an action on all shapefiles in a directory using arcpy. That said, it could be

Sometimes you just need the point coordinates for all the points in a GeoJSON. This function pulls them into an array.

This function takes an input GeoJSON dataset and creates a generates a hex grid from the bounding box of that layer.

Raleigh park Level of Service access points from March 2018. Not up to date, but potentially useful for testing purposes.

Mostly this is an example of what ESRI JSON looks like. It is useful for comparing to GeoJSON and for testing how to pull data from this format into PostGIS or geopandas.

Notes from DataCamp's "Intro to SQL for Data Science" course

A little function for use in ArcGIS to determine in a very particular case if a field is a 0 or a null. Turns null into -1 because shapefiles don't do null values. This is poorly documented...grr.
