Learn how to add layers and conduct simple manipulations in ArcMap (ArcGIS Desktop) and ArcGIS Online

Preparing the shapefiles

In this section, we will add the same layers we included in the ArcGIS online exercise into ArcMap.

To do so, we will download the shapefiles from the Las Vegas GeoCommons site (not the API!) as ZIP files, unzip them, and import them into ArcMap.


Start by going to the Las Vegas GeoCommons website. You can browse data by category (for example, Education or Existing Infrastructure); or you can simply search for the data by keyword.

Type "fire" in the search box, and select "fire hydrants" from the drop-down menu.

In the next screen, click on the Fire Hydrants link.

Go to Download and select Shapefile

The ZIP file will start downloading. Direct the download to a folder you will remember because we will return to this folder with each download and each shapefile retrieval. 

Use the file explorer to navigate to the folder and unzip the file by right-clicking on the file and selecting Extract all... and clicking Extract.


Now it's time to open ArcMap!

Establish a connection to the folder in which you saved the unzipped shapefile.

Go to the Catalog window, and click on the folder with a plus sign  to connect to a folder. Navigate to the folder in which you saved the unzipped shapefile. Click OK.

The folder will now appear in the catalog window under Folder Connection. 

Click on the plus sign to reveal the folder content until you see the Fire_Hydrants.shp file

Drag and drop the Fire_Hydrants.shp file into the Table of Contents window. Your screen will now look like this:

... which really doesn't look like much. Let's add a basemap for easier navigation. 

Click on the Add Data button and select Add Basemap

Select Light Gray Canvas and click Add. Ignore (for now) the transformation window. 

Move the map and zoom in until you find the CSN Charleston Campus (South of Charleston Blvd between Jones & Torrey Pines). You may have to turn off the Fire Hydrant layer to see better - just uncheck the box next to Fire Hydrants in the Table of Contents window. 

If you turned off the layer, turn it back on. Your map will now look like this:

Add the rest of the layers by following the same process. Although the colors and symbols of your map may vary, your map will look something like this:
