Step-by-Step Tutorial for AGOL Web Maps
This is an introductory tutorial how to create web maps and scenes in Esri ArcGIS Online (AGOL).
ArcGIS Online is Esri’s cloud-based platform for collaborating, sharing and connecting with geographic data.
In this ArcGIS Online tutorial, we guide you from start to finish to create and share web maps online.
As AGOL is easy to pick up and learn, we suggest you to experiment for yourself with this feature-rich platform.
Step 1 Log into your ArcGIS Online account
If you want to create an interactive web map with ArcGIS Online, you will need to create an account. Once your account has been approved, you can start interacting with the tools to build web maps, scenes and apps in ArcGIS Online.
After a bit of wait, you’ll have to log into your ArcGIS Online.
Step 2 Create a Web Map
The next step is to start creating a web map, web scene or app. But what’s the difference between them?
WEB MAP: A web map is a simple 2D viewer for geographic data. This 2D data could be vectors such as points, lines or polygons. And it can even include tables or rasters.
WEB SCENES: A web scene is a type of 3D viewer. Generally, the two types of scenes are local and global. For local scenes, the study area is small like a neighborhood. But for global scenes, the study area is much larger like a continent or ocean.
Let’s start by creating a simple web map. But you can apply the same steps below to web scenes.
Step 3 Add Title and Tags
The simplest option is to create a basic web map. If you select this option, you will have to provide a title and tags.
Once you’ve provided this, suddenly an empty web map appears in your browser. This is the interface for how to create your web map. In the screenshot below, we list some of the important tools to get started.
Step 4 Change the Basemap
The default base map is the “Topographic Basemap”. But you can change the base map by selecting the drop down. For example, there are basemaps for “World Imagery”, “Terrain”, “Streets” and “Oceans”.
In this example, we select the “Dark Gray Canvas” basemap.
Step 5 Add Data to your Web Map
Instead of a plain web map with only a base map, we should add data to it. And one of the reasons why ArcGIS Online is so good is because users can access and add an incredible amount of data to their web maps.
When you click the “Add Button”, there are select several options to add data.
SEARCH FOR LAYERS: When you search for layers, this is the massive cloud database as part of ArcGIS Online. You can find anything in here which includes authoritative and non-authoritative (so be careful). As of now, there are more than 500,000 layers.
ADD LAYER FROM WEB: This option is how to reference web services online. This usually is in the form of REST services, that you have to point to.
ADD LAYER FROM FILE: If you have your own data on your personal computer, then you can add data as a zipped shape file, CSV, TXT, GPX or GeoJSON.
USE MAP NOTES: This is how to mark up the web map with basic shapes. For example, AGOL has map note templates for infrastructure, civic events and citizen requests.
In our map, we have added earthquake events using the “Search for Layers”. Earthquake events are highlighted as orange points.
Step 6 Share your web map
Finally, you can share your web map. Once you click the share button, you can alter who can view the map. If you want the whole world to see, then you can select the check box for everyone.
Alternatively, you can share the map with a simple link. But if you want to embed your web map to a website, it provides code how to do so. Keep in mind that people can only access you map if you make it public.
Try it yourself
It’s time to sculpt some web maps of your own.
As you can see in this tutorial, you can work comfortably and create web maps with ease using AGOL.
In this tutorial, we changed the base map, added data stored in the cloud and shared it as a public map.
Now, you can experiment for yourself with interactive 3D web scenes or customized apps.
