Wagner Week 4

Chapter 5 was about caching and on-premises Web GIS. I learned about the need for on-premises and hybrid Web GIS, Arc GIS enterprise components and deployment, and portal collaboration. ArcGIS Enterprise is a variation of ArcGIS online that has four components: a portal for ArcGIS, an ArcGIS server, ArcGIS Web adapter, and ArcGIS Data Store. Portal collaboration is interesting and seems very effective for organizations to work together. I then read about raster tile, vector tile, map image layers, feature tiles, and publishing strategy. 

Chapter 6 was about spatiotemporal data and real-time GIS. Real-time GIS is used for objects and events that move, appear, and change through time. Spatiotemporal data can be categorized into: moving, discrete, stationary, and change. The time value of the data can either be a point in time or a duration of time. ArcGIS  Velocity and ArcGIS GeoEvent Server can connect to many kinds of streaming data, perform continuous data processing and analysis, and send updates and alerts when specific conditions occur in real time. This is amazing to me and I can think of so many applications that could use these. It then went more in depth about ArcGIS velocity and GeoEvent Server and then ArcGIS  Mission. 

I could create an application to show the population change of Delaware over time. I could get the data for the population over time and animate the data with a time slider then create a web app.
