Introduction to ArcGIS Online
ArcGIS Online is a cloud-based mapping and analysis solution. ArcGIS Online holds a collection of geographic information, and can be used to make maps and 3D scenes.
You can access ArcGIS Online here.
Upon entering the site with full access, a number of tabs will appear on the top and on the right-hand side. Click on each and see what they do.
You can also access the different products:
Map Viewer Classic
Find Map Viewer Classic and click on it.
A new tab should open. First let’s look changing the basemap and adding data to the map.
Change the basemap to Light Gray Canvas.
Click on Add then Browse Living Atlas Layers.
Then choose ArcGIS Online. This will access to all publicly shared data layers.
Search for the thameseels then click Add.
Add the tribs data as well.
Rearrange the layers.
Click on the three dots next to the tribs layer, click Rename and rename it to Rivers. Click ok.
Rename the thameseels_barriers to Barriers.
Hover over the Barriers layer and click on Change style.
Choose the attribute Surveyed.
Also change the style of the Rivers layer.
Click on Symbols then choose a blueish colour and make the line slightly thicker.
Using the three dots next to the Barriers layer, click on Configure Pop-up.
Change the Pop-up title, then configure the attributes displayed by ticking or unticking them.
Click on a barrier location and the pop will show with the details.
Save the map under Save as.
Let’s now look at Map Viewer.
In Contents, open the map you have just made in Map Viewer by clicking on the three dots next to it.
You should see the map you made appear.
Click Layers then Add Layers.
From ArcGIS Online search for thameseels and find the layer called RT. Add to the map. The layer showing the River Thames should appear.
Click on Edit layer style -> Style options -> Symbol style and change the colour of the fill and outline. Click Done.
Drag the RT layer to the bottom and rename it to River Thames.
Go to Basemap and remove the World Light Gray Reference layer.
If you click on the World Light Gray Canvas Base, you can play around with its properties.
Go back to Layers then click Labels and format the label field and style. The labels for each river should appear.
Save the map.
Web Mapping Application
Let’s create a web mapping application using the map created above.
Click on the map under the Content tab and click Create web app then WebApp Builder.
Give your app a title then click OK. Your map should appear.
Under the Theme tab you can pick a theme, change the style and layout of the app. Pick your prefered theme and colour.
Under the Map tab you can change the map extent, scale and so on.
Under the Widget tab you can add widgets to access the layers, legend, basemaps etc.
Let’s add the Basemap Gallery widget.
With a click and hold you can change the order of the widgets.
Let’s now add the Filter widget to be able to filter the barrier data.
Add the first expression for Feature. This will allow you to filter the data based on barrier type.
Add another expression for Pass, and choose Values filtered by all other expressions for both. This will allow the data to be filtered based Feature and then Pass, or Pass and then Feature. Also tick the box next to Zoom to the remaining features when the layer’s filter is applied and Zoom to the initial map extent when layer’s filters are all off.
Let’s try out the filter. Choose Eel pass.
The app will then filter the data in the background and will only give the option to look at those barriers that have eel pass.
The filter will work the other way around as well.
Depending on your data need, you can add more widgets. You can also edit the info under the Attribute tab.
Once you are happy, Click Save and then Launch.
Your app should appear in a new tab.
