Section Seven - The ArcGIS Help Menu

In order to become a GIS pro, utilizing the built-in help is essential. When ArcGIS is installed on a computer, the local help is also installed. Found in the Help menu in the menu bar, the "ArcGIS Desktop Help" option will open the local help. By opening the books along the left side will get you the help topic you need. If you know the name of the tool or action you are looking for, you can search for it in the Search tab.

Another version of the help menu is available online at… This page is updated when ever it is needed, versus the built in help, which is only updated upon software updates. Notice the tabs across the top:

An explanation of the various extensions in ArcGIS.

ArcGIS, a proprietary software, costs money, unlike a opens source software like QGIS.  And it costs a fair amount of money.  With the exception of K-12 school and humanitarian non-profits, companies need to pay for not only the base software, but also for any upgrades and additional advanced toolboxes.  In order to save costs, companies can elect to purchase the number of base licenses they need to match the number of employees and then just a few copies of the more advanced tools (called extensions to share among everyone.  This sharing process, in ArcGIS, is referred to as enabling extensions.  When an extension is enabled on one machine by a single technician on a shared company network, that extension cannot be used by any other technician on the same network until it is disabled by the first technician.  Think about it like a public library - Instead of purchasing tons of copies of one particular best-seller, they purchase a limited number of copies, then lend them out free of charge to their registered users. While the book is checked out, no one else can read it, as it is not physically available to any other reader while in possession of the first reader.  ArcGIS extensions work the same way - limited count extensions are only available to a few technicians at a time to check out (enable) and cannot be used by another technician until it is checked back in (disabled).

Enabling Extensions in ArcGIS
If an extension is available to a user but is simply not enabled, a warning message informing the user is presented.  When compared to the error message which appears when a tool is not paid for (below), this one looks quite a bit more scary when it actually means "need to check the box".
  1. open the Customize menu
  2. click on “Extensions” to launch the dialog box
  1. place a check mark in the box to the left of the extension name
  2. close the Extensions dialog box

If the extension is not available (not paid for or all the copies are checked out), instead of a check mark appearing in the box, a pop-up will appear stating “ The extension could not be activated. There is no license name currently available”

HOWEVER ArcGIS Pro authorizes extensions with the .prvc license file instead of using the extensions functionality. This is why it's important to authorize your ArcGIS Pro student software as Single Use with the .prvc file and NOT just signing in (which includes basic operations, no extensions)


When you visit the online help, you will notice it is set up a lot like this wiki (the other way around, really). That was an intentional effort to help make the transition from GIS 101 to utilizing the GIS help seamless.

When it comes to learning to use the software beyond this class, the ArcGIS help menu is the best resource out there (beyond taking more GIS classes, but even then, you’ll use the help menu). I, and every GIS technician/analyst I know, use the help on a very regular basis, if not daily. From looking up tools to remember which tool does what to finding the proper Python syntax when writing custom tools, ESRI has done a really good job with the help menu. Throughout the wiki, you will find links to ArcGIS help articles for various tools and processes. Clicking through the link and skimming the article is considered mandatory in this class, since the overall goal is to prepare you to be an independent GIS user. Learning to read help articles is fundamental to the process of developing good software skills.
