I have been teaching GIS at the introductory level for a few years now. Everything I have learned I have taught myself and feel pretty competent for someone without a degree in GIScience, but only with regard to ArcGIS Desktop and ArcGIS Online. My next challenge is to set up one of our school's servers as a source for hosting content as opposed to using our AGOL institutional account. I have installed and authorized Arc Server 10.2.
Initially, I would like to be able to just publish a feature service from desktop to our server and access it through AGOL. Is there a good educational resource, aside from spending over $1,200 at the Virtual Campus, to learn the basics?
