So far we’ve brought in web services from a few different servers in order to get a multidimensional picture of conditions around Mount Rainier. In many cases you might want to add your own data to supplement whatever web services you find. Suppose you’re going to be hiking on a section of the Wonderland Trail, which encircles Mount Rainier. Let’s add this trail to our map by uploading a shapefile to ArcGIS Online. This dataset was adapted from a file geodatabase feature class downloaded from the Washington State Recreation and Conservation Office public download page.
- In arcgis.com, open your Hiking Conditions map from the previous section of the lesson.
- Click Add > Add Layer From File.
- Browse to wonderland.zip and click Import Layer. Notice all the different data formats you can import.
This is just a zipped shapefile. After the layer imports, you’ll be prompted to define the symbol. You can style the layer based on some attribute or just define a single symbol to be used.
- From the Choose an attribute to show dropdown, choose Show location only.
- In the Select a drawing style area, click the Options button and choose to symbolize your trail using a thick brightly colored line. Then click Done.
Your map will look sort of like this, although it will probably have more snow on it.
- Save your web map again.
Your data is saved inside the web map. This works fine for small datasets that need to be used on a limited basis. There may be other situations where you want the data to be available to multiple web maps, or at multiple offices. In this sitation you can publish the data as a service running directly on ArcGIS Online (with no ArcGIS Server needed). We will do this in the next section of the lesson.
