Sharing your Map on the Web

You will  need a ESRI Global Account to enable you to login to ArcGIS Online. If you do not already have an ESRI Global Account, go to: and create one.

In the first part of this exercise using ArcGIS Desktop, you will be working with the following spatial datasets:
  1. A polygon shapefile of the your study area, called Watershed
  2. A line shapefile of river network, called River
These shapefiles consist of several files (e.g. river.dbf, river.shp, river.shx).
You need to establish a working folder to do the exercise on. This can be in c:\temp, your student directory, or on a memory stick attached to the machine you are working on.
To open your shapefiles within ARCGIS online, you need to first zip your files and upload it through ARCGIS online service
Go to add>add layer from file>Browse>WATERSHED.

Now let’s suppose you want to Share this map with colleagues online.

I am a member of a number of Groups in ArcGIS Online, and I could choose just to share my map with one or more of those, but instead, let’s share the map to Everyone (public), and that way anyone can see it. I get back a web link for this

And if I put this address into a web browser, my map appears again! Ok, this is pretty cool. I’ve created a map on the web and shared it with others.

STEP 1: We will create a mini project in this course and you would be able to learn about some of ARCGIS cool options. Firstly we will work on preparing  GIS basic coverage for a watershed. You can extract the study area characteristics like area, river slope, min and max elevation etc. Besides you learn some ARCMAP extensions.

STEP2: Creating some kind of hydrology maps like flow direction and flow accumulation. We will also work on river profile and plot main river profile for your study area.

STEP3: Finally Share your maps with colleagues online.

Student Installation of ArcGIS 10.2 for GIS in Water Resources
University of South Carolina (USC)

September 2013

There are five steps to this process (these are for your information only, since ARCGIS is already installed in computer lab):
(6) Activate ARCGIS extentions

Here are the instructions for these steps:

(1)  ESRI Global Account

If you already have a Username and Password for your ESRI Global Account, then skip this step.

If not, go to and choose Create an Account.  You’ll be presented with a large screen with a lot of information that needs to be filled in.  Fill out this screen and choose Create Account at the bottom.  This will establish your User Name and Password for ArcGIS Online and for validating your software.  If you have not yet emailed me your ESRI Global Account username, please do so now.

(2)  Prepare Your Computer

(a)  Check the ESRI System Requirements to make sure your computer has the required hardware and software to support the installation of ArcGIS 
Be careful to ensure that your computer has the right operating system and also the necesssary Service Packs installed for that operating system.  If you’ve had your computer for a long time and not installed any Service Pack updates, your operating system might not be up to date enough to run ArcGIS Desktop.

(b)  If necessary, install the Microsoft .NET Framework.  This is the most important part of installation. Sometimes model gives NET Framework error which you got to install it properly.

(c)  If you already have a previous version of ArcGIS Desktop installed on your computer, you’ll need to Uninstall it before installing the new one.  To do this, Go to Control Panel/Programs and Features and right click on the icon for ArcGIS and follow the Uninstall instructions.

(3)  Obtain an Authorization Number and the Software

You need to get an authorization number to use ARCGIS Desktop software and its extentions.

You will be presented with a choice as to Versions, choose Version 10.2

In the succeeding menu, select “ArcGIS for Desktop” Download (811 MB).   This takes a little while.

You should end up with a single file that looks like this:

(4)  Install the Software and Validate your Authorization Number

Double click on the file ArcGIS_Desktop_102_135756.exe and install it on your computer.    This takes quite a while, so you might want to get a cup of coffee or do something while the installation goes on.

Immediately that your software installation has been completed, you’ll be presented with a ArcGIS Administrator Wizard screen.  Select Advanced (ArcInfo) Single Use  and you’ll see the button, Launch the Authorization Wizard for Single Use Products be activated.

Hit Authorize Now  and enter your Authorization Number

Enter the same Authorization Number to license the extensions to ArcGIS Desktop.  You can license all the extensions if you want to.  We’ll use Spatial Analyst and 3D Analyst etc.  in the class exercises and you may want also to license for example the Geostatistical Analyst. You have to fill in the right hand side box with your Authorization Number by each extension that you want to authorize.   It’s not immediately obvious that this is necessary when the screen appears in front of you.

Finish this process and you are done!

5.  Start Using the Software

Open ArcMap and select the A new empty map option.  If you are using Windows 7 or Windows XP, hit the Start button and you’ll see a series of options for ArcGIS.  Select ArcMap. 
If you are using Windows 8, you’ll see  in your Windows display.  If you don’t see that, then just type “ArcMap..” and you’ll see the program symbol appears.

6. Activate ARCGIS Extensions
After launching the software, you need to properly activate the extensions. Go to Customize/ Customize Mode, and select each extension which you need to work with.

Ok, you are good to go now!
