More than just points on a map


The latest release of ArcGIS Online is now packed with more functionality than ever including 12 new “Perform Analysis” tools. These new tools  now give you the ability to do things like Finding Hot Spots, Enrich your Layers, Merge Layers  and Overlay Layers. This is just the tip of the iceberg though with more to be released soon.

Let’s have a look at the tools in the Use Proximity toolset:

  •   Create Buffers,
  •   Create Drive-Time Areas and,
  •    Find Nearest.

Before you go and use these tools you need to have some data to work with so select yourself a basemap and choose some point data (or add your own). I thought I’d have a look at analysing dog parks in Brisbane.

The Perform Analysis tools appear in the context menu for your data.

3_Buffer

I had a look at the Buffer tool to identify areas in Brisbane that are within two kilometres of a dog park which can be seen in blue below which was helpful but I wanted a bit more information.

But you can just as easily apply a drive-time or driving distance analysis to the same layer giving you a better understanding of the spatial relationship. Below displays a 5 minute drive-time using the dog parks layer:

You could also use the Find Nearest tool using the same Dog Park layer to find the closest dog park to your home. You can choose between closest Euclidean distance (straight line), driving distance or driving time. Additionally there is functionality help you to identify multiple nearest features. I used drive time to find the closest dog park to our home.

As you can see, ArcGIS Online is able to identify the nearest dog park, as well as find a route using the streets from the basemap.

If you are mindful of the number of credits the analysis is consuming, you can always check how many credits you have used by navigating the Show Credits link beside the Run Analysis button.

As you can see, ArcGIS Online Spatial Analysis tools are a great way to easily conduct analysis without having to purchase the Spatial Analyst Extension and as always can be easily shared throughout your organisation.
