New: ArcGIS 10 tutorials

This page provides a set of various ArcGIS tutorials used to perform a number of common tasks in ArcGIS. Find the tutorial that you would like to work through by clicking the links below. These are Esri tutorials

To work through the ArcGIS Desktop tutorials, you need to install the tutorial data from the ArcGIS Desktop Tutorial Data setup, which is part of the ArcGIS Desktop installation download or media. If the tutorial data has been installed on your system, look for it in C:\arcgis\ArcTutor (the default installation location). In many cases, you will need write access to that location to perform the tutorial.

The ArcGIS Server Installation does not include tutorial data. Most of the ArcGIS Server tutorials are written in a generic way so that you can follow the steps using your own datasets.

These tutorials are published by ESRI:

Database servers:

This tutorial shows you how to use ArcGIS Desktop to use database servers (instances of SQL Server Express) and the geodatabases you create on the database servers to store, access, and edit GIS data. An ArcEditor or ArcInfo license is required to complete the tutorial.

Image classification methods in the remote sensing

Digital image classification assigns pixels to classes. Each pixel is treated as a set of values in several spectral bands, derived from the brightness of the same area on the earth's surface. By comparing pixels to one another, and to pixels of known identity, it is possible to assemble groups of similar pixels into classes that are associated with the informational categories of interest to clients. Because these classes form regions on an image, after classification, the digital image is presented as a mosaic of uniform parcels, each identified by a color or symbol. These classes are, in theory, homogeneous-- pixels within classes are spectrally more similar to one another than they are to pixels in other classes. In practice, of course, each class will display some variation, because category exhibits natural variation. Image classification forms one of the most important tools for examination of digital images--sometimes to produce a final product, other times as one of several analytical procedures applied to derive information from an image.

Image classification requires the analyst to matchinformational classes to spectral classes. Informational classes are the categories of interest to the ultimate users of the data. Informational classes are (for example) the different kinds of forest, or the different kinds of land use that convey information to planners, managers, and scientists who will use information derived from remotely sensed data. These classes convey the information that we wish to derive from the data--they are the object of our analysis. Unfortunately, remotely sensed images do not directly convey informational classes-- we can derive them only indirectly, using the brightnesses that compose each image. For example, the image cannot directly show geological units, but rather only the differences in topography, vegetation, soil color, shadow, and other factors that lead the analyst to conclude that certain geological conditions exist in specific areas.

In contrast, Spectral classes are groups of pixels that are uniform with respect to brightnesses in their several spectral channels. The analyst defines spectral classes within remotely sensed data; then must define links between spectral classes on the image and informational classes that are of interest to the client. In this manner, image classification proceeds by matching spectral categories to informational categories. If the match can be made with confidence, then the information is likely to be reliable. If spectral and informational categories do not correspond, then the image is unlikely to be a useful source for that particular application.

Informational classes are typically composed of numerous spectral subclasses--spectrally distinct groups of pixels that together may be assembled to form an informational class. In digital classification, we must often treat spectral subclasses as distinct units during classification, but then display several spectral classes under a single symbol for the final image or map to be used by planners or administrators (who are, after all, interested only in the informational categories, not the intermediate steps required to generate them).

Overview of Process of Supervised Image Classification

1. select prospective training areas (training data polygons)
2. evaluate the training areas on the basis of
   • visible features
   • normalilty
   • separability
   • partitioning
3. make decisions on which training areas to use
4. classify the scene
5. evaluate the accuracy using an error (contingency) matrix

Unsupervised classification can be defined as the identification of natural groups, or structures, within multispectral data. The notion of the existence of natural, inherent groupings of spectral values within a scene may not be intuitively obvious, but it can be demonstrated that remotely sensed images are usually composed of spectral classes that internally are reasonably uniform in respect to brightnesses in several spectral channels. Unsupervised classification is the definition, identification, labeling, and mapping of these natural classes.

What is ArcGIS Server on Amazon Web Services?

ArcGIS Server on Amazon Web Services allows you to deploy ArcGIS Server on the Amazon Elastic Compute Cloud (EC2). ArcGIS Server runs on Amazon's hardware and is administered through web services.

Advantages of deploying your server on Amazon EC2 include the following:

• No installation required—You don't have to install ArcGIS Server yourself. Instead, you use a downloadable utility, ArcGIS Server Cloud Builder on Amazon Web Services, to create your ArcGIS Server site on Amazon EC2. Once you create your site, you can immediately connect to it and begin publishing services from ArcMap.
• Scalable on demand—You can configure your site so that additional GIS servers are added in response to certain triggers, such as CPU usage. New servers can be created in a matter of minutes, allowing your site to gracefully respond to abrupt spikes in traffic. When you no longer need the instances, you can destroy them and incur no further charges for them.
• No hardware infrastructure to maintain—Deploying ArcGIS Server on Amazon Web Services requires no special hardware; you just have to be able to connect to the Internet. After creating your site, you can gain fine-grained management of your server through the AWS Management Console, a web application provided by Amazon. You can log in to your server through Windows Remote Desktop Connection to fine-tune your data, services, and applications.
  Deploying your server in a cloud environment allows you to use as many or as few computing resources as necessary without committing to a long-term purchase of hardware or other IT infrastructure.

About this help

This help system focuses on how to deploy ArcGIS Server and use enterprise geodatabases on Amazon EC2. It also includes special topics about maintaining and scaling your deployment on EC2.

If you need general information about ArcGIS Server or enterprise geodatabases, you should visit the ArcGIS Help. The ArcGIS Help describes how to publish services, configure security users and roles, create web applications, build geodatabases, and so on.

Links to the ArcGIS Help are provided throughout this help system where appropriate.

What is Cloud Computing

It's virtual

Imagine racks of servers, humming along in a data center. Together, these servers become a massive pool of resources. Divide this "pool" into multiple virtual servers, and you create a "cloud."

It can be secure

For the utmost security, create a private cloud on dedicated hardware. But always remember to put appropriate security measures in place, no matter which cloud you choose.

It's flexible and scalable

Since virtual servers aren't physical, they are super flexible, giving you what you need at the moment. Spin up a server in minutes, and take it down just as easily.

It can be affordable

You'll get the greatest cost savings in the public cloud, where your virtual servers run on physical servers that you share with other customers.

It's open (or closed)

In the open cloud, you can easily move your cloud around—without being locked into one provider or a closed, proprietary technology.

It can be secure and affordable

A hybrid cloud gives you the benefits of both public and private clouds. For example, you can put public-facing components in a public cloud, while storing customer-sensitive data in a private cloud.

Why Use Cloud GIS?

When you run GIS software and use GIS services in the cloud, you, or more likely your organization and your customers, may realize many of the same benefits other software and services users discover when they start their work in cloud. 

Common benefits include

No more software updates

In the cloud, the end-user is most likely using the latest, greatest version of the software or service. They don’t have to worry about installing or configuring software updates and can take advantage of new features right away, as they become available.

Convenient access to services

The organization is able to make its online services available to customers 24/7 (always on). This means that the business of the organization continues beyond the regular work day - letting customers use the software and services when they need it, at any time, from anywhere in the world.

Pay only for what you use

Using cloud services means that both the customer and the organization can take advantage of more flexible business models, which make it easier to budget for services rendered and, in the long term, may lower the overall cost of ownership. The cloud also makes computing extremely scalable, allowing you to quickly increase capacity during peaks of high demand and then scale back down when demand returns to normal levels.

Cloud GIS includes all of these benefits, in addition to making it easier to test and deploy GIS applications, which can improve your organization’s responsiveness and competitiveness. You may also find that Cloud GIS provides you with a more collaborative environment, particularly for your mobile workers and customers or if you have multiple offices located in different cities around the world.

Public and Private Clouds

Typically, cloud computing platforms can be public or private. In the public cloud, the infrastructure and applications are owned by the cloud vendor and essentially leased to the cloud consumer. A private cloud operates behind an organization’s firewall and is maintained within the parameters of the host organization, although the infrastructure and applications can still be owned by a cloud provider. Private clouds are becoming increasingly more popular.

 Many believe that the “sweet spot” for cost optimization in the cloud relies on a delicate balance of public and private clouds – often referred to as a hybrid solution. For cloud GIS users, this means taking advantage of GIS software and services within on-demand infrastructures, taking full advantage of both on-premise and off-premise, depending on the business needs or restrictions of the organization.

Topics in Cloud GIS

Imagine that all the GIS tools, imagery, basemaps, and databases you need to do your work are organized for you somewhere out there on the web. You can access those resources at any time, from your desk at work, from home, while you’re traveling; your data storage capacity increases automatically as you need it; and you can share your work instantly with colleagues or customers across the globe.

This is idea behind Cloud GIS – seamless access to GIS capabilities from anywhere.

What Is Cloud GIS?

Cloud GIS is the combination of running GIS software and services on cloud infrastructure and accessing GIS capabilities using the web.

Cloud computing offers an alternative to traditional methods of delivering and consuming GIS software and services to your customers.

Instead of running GIS on your own compute systems and operations, with Cloud GIS, your software and services reside on infrastructure – commonly (but not always) maintained off premises by a third party vendor – and made available through web technologies.

For a more detailed definition of cloud computing, see The National Institute of Standards and Technology (NIST).

NOTE:

Why am I asked for a password when I try to add an ArcIMS Internet MapService to ArcMap?

All of the data and services provided by PASDA are free and open to the public; nothing requires a password. If your computer is on a network that includes a Proxy Server, you may be prompted for a password due to your network settings. You should check with your network administrator to confirm whether you have a proxy or not. If you do have a Proxy Server the easiest way to resolve this issue is to add your Proxy Server information to ArcCatalog. In ArcCatalog select Tools - Options - Proxy Server and enter the information supplied by your network administrator. Once that is done you should not be prompted for a password when connecting to PASDA services. If you are using ArcGIS 9.2, you can provide the Proxy Server information in ArcCatalog by selecting Tools - Options - Connections. You may also need to make changes to your Internet Settings in the Windows Control Panel. Consult with your network administrator to help with your particular configuration.
