Esri Map Service Loading & Error Events in Leaflet.js

Over the summer, we were having a recurring issue where our map services on ArcGIS Server were down.  It seemed to happen at random times.  I even received an e-mail while at a picnic about a service being down.  While this was annoying, more concerning was that my web maps built using Leaflet.js and consuming …

Automating File Transfer from an FTP Site With Python

I wanted to share a project I'm working on as part of my involvement with South Central Task Force GIS Workgroup.  As part of our monthly regional data update process, a file geodatabase is created.  It contains updated versions of various datasets ranging from road centerlines to parks.    The geodatabase is zipped and placed …
