Creating a Map and Adding Map Notes

• • Go to arcgis.com and click Sign in. You will see the window on the right, click on "Enterprise Login"

  • You will be asked to Enter your ArcGIS organization's URL. Type clemson in the box and click Continue.

  • Click on the blue box that says "Clemson University"

  • Log in using your standard Clemson username and password.

  • Once you are signed in, go to Map at the top of the page. The page will open to a default map showing North America.

2. Creating a new map

When this new map opens, you will notice it is not empty. A basemap is shown, which is a foundational layer which can be displayed with a variety of other data. These have different styles, such as political maps, streets maps, aerial and satellite imagery, or thematic maps.

• • In the upper left section, click the Basemap button and select a new basemap. Try a few different styles, such as Imagery with Labels, Dark Gray Canvas, and Streets.

Practice zooming in and out using the roller button in your mouse. Zoom in to a particular location to examine the level of detail available in each basemap.

We will change the plain symbology of the campus parking lots to one where each type (Resident, Commuter, Employee, etc) has a unique color.

• • In the Contents section, hover your mouse over the ParkingLots_CU_2016_example layer. click the Change Style symbol below the layer's name.

The default is to show only the location and use the same symbol. In this case, it's a gray polygon.

• • Under Select a drawing style, click Options.

• Click the gray box next to the word Symbols.

• Click a new color for the parking lots, then click OK. Notice the change in the map. Click OK again.

  • Under Choose an attribute to show, click Type. Then click Options under Types (Unique Symbols).

• Click the word Symbols and select the second color ramp from the top left corner and click OK.

• Adjust the Transparency slider to your desired level.

• Click OK and Done to close the window.

As you can see, setting up the symbology is quite easy to do but can be totally customized as you desire. Let's help identify particular parking lots by labeling them with their names, such as E-11, C-2, etc.

• Hover your mouse over the ParkingLots_CU_2016_example layer and click the three dots for More Options.

• Click on Create Labels. You can adjust the font size and text color, such as dark gray text with 11 point size. Click OK when finished.

Your map has come a long way in a short time!

7. Adding your own Map Notes

Map Notes are an easy feature to make annotations. You may want to highlight a feature, note a place for observing in the field, or to compare against another map layer. You can add on-the-fly data by adding Map Notes. Imagine, in our case, that we want to find potential locations to build a small dog park on campus that is open to students and the community alike. We will propose a site by dropping a pin on the map as a Map Note.

Click on the Add button -> Add Map Notes.

Name: Dog Park Candidate

Template: Map Notes

You will see the Add Features panel.

• • Click on the Stickpin to add a new point. Call it Dog Park Location.

  • Click on Freehand Area and draw in a boundary for your dog park. Make it as large or small as you like. Type a title, such as Dog Park Boundary

  • When finished, click the Edit button to leave the edit mode.

8. Perform a GIS analysis: Calculate Drive-time Areas

There are many potential analyses that can be performed in ArcGIS Online. Let's try an example which demonstrate the capabilities of GIS to solve spatial problems. We will do a drive-time analysis to show the area which can be accessed within a particular driving time of a location. This uses a special network dataset which includes roads and travel times, then solves to find areas which can reach our destination within a specified time.

For our drive-time analysis, let's continue with our dog park we just created. We know students and employees will propbably use it, but many community members may travel to campus to use it as well. We want to know what area would be served with both a 10 and 20 minute drive from campus to estimate what areas are most likely to reach it.

• • On the top of the screen, click the Analysis button. Click Use Proximity and click Create Drive-Time Areas.

  • Fill in the following information:

    • 1. Make sure the point layer is set to the Dog Park Candidate (Points).

    • 2. In the box for times, type 10 20. Make sure the options are set to Driving Time and Minutes.

• Click on the Show credits. Notice that this analysis will take 1 credit from your account (you have 1,000 credits to begin with!)

• Click Run Analysis and after a minute or so the new layers will be added to the map. Zoom out to see the result.

What towns/cities are contained by a 10 minute drive time? What cities are served within a 20 minute drive time?

What area (sq. mi.) is served within a 20 minute drive time? (Hint: look at the attributes!)
