Q

LEARNING OUTCOME: Define and distinguish “Cloud”.

A

“The cloud” refers to servers that are accessed over the Internet, and the software and databases that run on those servers. Cloud servers are located in data centers all over the world. By using cloud computing, users and companies do not have to manage physical servers themselves or run software applications on their own machines.

Q

LEARNING OUTCOME: Define and distinguish “serverless architecture”.

A

“Serverless architecture is an approach to software design that allows developers to build and run services without having to manage the underlying infrastructure. Developers can write and deploy code, while a cloud provider provisions servers to run their applications, databases, and storage systems at any scale.”

Q

LEARNING OUTCOME: Define and distinguish “Virtualization”.

A

Virtualization is a process that allows for more efficient utilization of physical computer hardware and is the foundation of cloud computing.

Virtualization uses software to create an abstraction layer over computer hardware that allows the hardware elements of a single computer—processors, memory, storage and more—to be divided into multiple virtual computers, commonly called virtual machines (VMs).

Q

LEARNING OUTCOME: Define and distinguish “VDI”.

A

Virtual desktop infrastructure (VDI) is the hosting of desktop environments on a central server. It is a form of desktop virtualization, as the specific desktop images run within virtual machines (VMs) and are delivered to end clients over a network. Those endpoints may be PCs or other devices, like tablets or thin client terminals.

Q

LEARNING OUTCOME: Define and distinguish “AGO”.

A

“ArcGIS Online is a software-as-a-service (SaaS) offering of Web GIS. ArcGIS Online is hosted on the Amazon Web Services (AWS) cloud and Microsoft Azure cloud platforms and is managed by Esri. There is no hardware infrastructure for an organization to maintain. ArcGIS Online hosts hundreds of millions of content items and registered users. It serves billions of maps per day with high performance, scalability, and availability. With the benefits of cloud computing, ArcGIS Online has been quickly adopted by government and commercial organizations around the world.”

Q

LEARNING OUTCOME: Define and distinguish “ESRI-portal”.

A

“Portal for ArcGIS allows you to more tightly integrate with your GIS server and your network environment. Portal for ArcGIS is a more appropriate choice than ArcGIS Online if any of the following conditions exist:

  • You require full control over the hardware running the portal in order to maintain a particular service level agreement (SLA).
  • You will allow service publishing from the website and your data is prohibited from being physically stored off-premises.
  • Computers in your organization are not connected to the Internet or have an unreliable Internet connection.

Some capabilities such as sharing the security settings of your organizational users and your ArcGIS Server site, are only possible in Portal for ArcGIS”

Q

LEARNING OUTCOME: Define and distinguish “ArcGIS server”.

A

“ArcGIS Server is a back-end server software component of ArcGIS Enterprise that makes your geographic information available to others in your organization and, optionally, anyone with an internet connection. This is accomplished through GIS services, which allow a server computer to receive and process requests for information sent by other devices.”

Q

LEARNING OUTCOME: Discuss the capabilities of ArcGIS Field Maps.

A

“ArcGIS Field Maps allows users to capture accurate data and return it to the office. It provides the following capabilities:

  • Collect and update data using the map or GPS.
  • Download maps to your device and work offline.
  • Collect points, lines, areas, and view related tables.
  • Design easy-to-use smart forms.
  • Attach photos to your features.
  • Use professional-grade GPS receivers.
  • Search for places and features.
  • Support high-accuracy 3D data collection capabilities.”

17
Q

LEARNING OUTCOME: Discuss the capabilities of Survey123 for ArcGIS.

A
  • Design smart surveys with predefined questions that support domains (which appear as the choices in drop-down lists) and feature templates, default values, embedded audio and images, and simple (for example, if the answer to one question is yes, show a related question; otherwise, do not show the related question) and sophisticated rules.
  • Capture field data using an intuitive, formcentric data-gathering solution.
  • Store survey results in hosted feature layers that you can share with organization users.
  • Perform online and offline data collection.

Fu, P. (20220712). Getting to Know Web GIS, 5th Edition. [[VitalSource Bookshelf version]]. Retrieved from vbk://9781589487284

19
Q

LEARNING OUTCOME: List the benefits of Web GIS.

A

“Global reach: You can share your geographic information easily, within your organization and with people all over the world.

Large number of users: You can share your app with dozens, or even millions, of users supported by scalable cloud technology.

Low cost per user: The cost of building one Web GIS app is often lower than building a stand-alone desktop solution and installing it for every user.

Better cross-platform capabilities: Web apps, especially those built with JavaScript, can run on desktop and mobile browsers running a wide range of operating systems, including Windows, Mac OS, and Linux, along with iOS, Android, and Windows Phone.

Easy to use: Web GIS apps typically incorporate simplicity, intuition, and convenience in their design. Public users can use these apps without a technical background (see figure).

Easy to maintain: Web clients can benefit from the latest program and data updates each time they access a web app. The web administrator does not have to update all the clients separately.”

Q

LEARNING OUTCOME: Define and give examples of IaaS.

A

“It allows organizations to purchase resources like networking and storage on-demand instead of having to buy costly hardware. IaaS is highly scalable and offers businesses more flexibility than on-premise solutions.”
