GIS Section 5.3 Flashcards
What’s the difference between the internet and the web?
- internet links computers to other computers (internetworking)
- web is software that lets users access or contribute content to the internet
ie. the internet connects computers, the web connects people
How is WebGIS nested in GIS?
GIS > Distributed GIS > Internet GIS > WebGIS
When is a system called Internet GIS?
when it uses internet services, not just web services
When is a system called webGIS?
when it only uses web services, not internet services
Which is more common between WebGIS and InternetGIS? Why?
Web GIS
- it is more attractive to people (easy to use?)
What is webGIS?
a GIS system that uses web technology to communicate among different components of a system ( a kind of distributed GIS)
What part of webGIS is changing how we do business?
- development of small sensors that provide real-time spatial data (Spatial Internet of Things!)
What is a recent change in how we do networking?
shift from functionality to interoperability
What is interoperability?
bridge between locations, platforms, operating systems, object systems, programming languages
What are some parts of WebGIS architecture?
Users interact with applications <-> services on the Web (also interact with other applications) <-> Data
How is real-time mapping (IoT) tagged?
based on time and space
What is the Sensor Things Standard?
open standard for IoT devices that enables interoperability, allows different networks of sensors to coordinate (ex. COVID-19 tracking)
What are Spatial Data Infrastructures (SDIs)
- many pieces of internet infrastructure independent of individual organizations
- cooperative linkages
- Open Geospatial Consortium (OGC) approach
What is XML?
eXtensible Markup Language - non-proprietary, interoperable language
What is CORBA?
Common Object Request Broker Architecture
