Creating & Importing Data for ArcGIS

geographic formatting & spatial dataframes

Last time we installed ArcGIS with minimum fuss and began exploring their mapmaking tools, including raster pixel tilings and searching for more pre-uploaded GIS items online.

However, there’s a fairly fundamental rule of data science:

The data you want usually isn’t in the place or shape you want it to be.

This is one reason why I believe data science careers are fairly safe from AI replacement. Machine learning is great at re-treading previously seen pathways, but the first 80% of the data process — ETL, including cleaning and migrations — is variable enough to require human input.

It could also be that the people researching AI algorithms aren’t interested in making themselves obsolete, but I doubt it; the drive to automate and simplify your own workflow is generally too high for such far-flung fears.

Sourcing Proper Data

Let’s explore ArcGIS’ native data creation & import settings before running some more visualizations.

For any meaningful analysis you’d like to do, the data probably isn’t already up on the ArcGIS cloud and neatly formatted for feature layering, though they do have some nice searchable layers already…
