ArcGIS API for Python / By

Today’s blog post is inspired by a question posed on Esri Communities. The question asks how to export hosted feature layers using only the ArcGIS API for Python, and specifically states not to use ArcPy.

A decade ago I purchased the first edition of Learning Geospatial Analysis with Python by Joel Lawhead. I was fresh from graduating from the MSc in Geocomputation at Maynooth University where our lecturer, Martin Charlton, gave us a term I will always remember, “buttonology”. Buttonology, he described, was the pushing of buttons in ArcGIS (or …

Discuss the Differences Between Geographical Information Systems & Geographical Information Science.

GIS / By

I was digging through some material from my MSc in Geocomputation from Maynooth University and came across this exam question. The MSc was fantastic. We had access to the brains of Chris Brunsdon the late Martin Charlton, two of the three people (Stewart Fotheringham, another stalwart in geospatial statistics was the third) that gave us …
