You can author and share web scenes containing the results of your Space Time Pattern Mining analysis. The interactivity of web scenes can be very useful when telling the analysis story and sharing and communicating your findings. The following steps reference a 3D web scene created for the story map Analyzing traffic accidents in space and time.
Share a space-time cube as a web scene
To share a space-time cube as a web scene, complete the following steps:
- After running the Emerging Hot Spot Analysis or Local Outlier Analysis tools (this example will use Emerging Hot Spot Analysis results), insert a New Scene.
- In the Scene view, run the Visualize Space Time Cube in 3D tool (or use the Space Time Cube Explorer Add-in), pointing to your existing .nc cube containing the analysis results on disk.
You may need to increase or clear the Visibility range by right clicking the layer on the Contents pane and selecting Properties which will open the Layer Properties window.
Your 3D results should look something like this:
- Disable Elevation Services by right-clicking the Scene and selecting Properties. Select Elevation Surface and disable any sources by clicking the red X for any active elevation services.
- Right-click the layer in the Contents pane, select Properties and navigate to the Display options. Check on Display 3D symbols in real-world units, the Display field should be set to Hot Spot Analysis bin (COUNT). The Layer 3D to Feature Class tool (step 6) will not work unless the layer is using real-world units.
- Right-click the layer and select Symbology. On the main Symbology pane (with Unique Values in the drop-down on top) click the and select Vary symbology by attribute. Expand Size, if necessary. Uncheck Maintain aspect ratio. The Height and Width options control how tall and how wide each bin is. To optimize visualization of your cube, these values can be adjusted. This example used a Height expression of 330 and a Width expression of 1800, but you can experiment to find optimal settings for your data. (Click to the right of the Height and Width fields in order to enter an expression). These values will be specific to the size of your space-time cube and the number of time slices it represents. You will want to make sure the settings leave a little vertical gap between the space-time bins.
- Run the Layer 3D To Feature Class tool to convert the extruded symbols to a multipatch feature class.
- The next step is to optionally configure the popups. First, create any fields you may want to display in the feature class you just created in step 6 (v3DCrashTrendsFC). For example, Clustering and Significance fields. Next, right-click the feature class you just created and select Configure Pop-ups. In the following, the title has been changed to Bin Data and set to only display the count, clustering and significance fields.
- On the Share tab in the Share As group, click Web Scene (Make sure you are signed in to ArcGIS Online or a portal. If you are not logged in, the Web Scene option will not be available.) This will open the Share Web Scene pane. Enter a name, summary and tags for the web scene and Share. Once the Scene has been successfully shared, click the Manage the web scene link to administer the web scene. It can now be shared with others, used in a Web App or added to a story map. Select Open in Scene Viewer to change the basemap, select either Default or ArcGIS Pro navigation and set the zoom and tilt. You can also configure the layer to include the popups you created.
