Chapter 5:
- On premises and hybrid web GIS are two alternative forms of ArcGIS, where the infrastructure used to host ArcGIS Online and its capabilities is owned by the organization using it, rather than Esri’s own hosting
- This has a variety of uses, including for organizations with unreliable internet access, or in the case where enterprise ArcGIS is needed, to access additional functionalities such as geoprocessing and image services, or for sensitive or secure data.
- ArcGIS Enterprise can be deployed either on local or cloud infrastructure, and is designed to integrate with cloud hosts such as AWS or Microsoft Azure
- There are many components to ArcGIS Enterprise, such as the server that hosts it, Portal, Web Explore and Data Store
- Enterprise can host a variety of data types, including specialized feature layers, and allows for interdepartmental operability through use of groups
- By first joining an Enterprise portal, and then sharing layers, you can add data to an ArcGIS enterprise group.
Chapter 6:
- Spatial-temporal data is GIS data collected where both time and location are important factors.
- This includes data like current traffic conditions, changing temperatures, weather or even things such as urban growth or road development
- IoT is the Internet of Things, which is a term describing the distribution of internet connected technologies with sensors, or other data collection means that allow them to interact with the world around them.
- Smart cities are cities that utilize IoT devices to constantly monitor and react to changing conditions, in order to function more efficiently
- ArcGIS GeoEvent Server is used to collect, ingest and process spatial-temporal data for GIS uses, allowing for real time monitoring of events and changes in the world.
- Additionally, GeoEvent server allows you to archive data for future reference or investigation, and allows for real time data delivery
- ArcGIS Online allows you to create maps with real time data layers, and operations dashboards for monitoring data and conditions in real time.
- Actions can also be used to trigger certain in case of certain events, or to active tools such as filtering or graph generation
One possible application of real time maps would be for a shipping company to use it to monitor traffic patterns and accidents, so they could efficiently reroute their drivers to ensure packages arrive on time.
