Incident Analyzer - Attribute interpolation

Dear all,


I'm starting a 14 test days on Incident Analyzer. Is it possible to interpolate the point data using the values of an attribute?


For example I have the value of the speed (mm/h) for each point and would like to interpolate them and have some charts. Is it possible?

Re: Incident Analyzer - Attribute interpolation

It is possible to create a hotspot thematic layer using the Evaluate point size in meters option.


To do this, try the following:


  • Start Incident Analyzer
  • Ensure the Data Sources tab is active tab.
  • Use the Click to Browse of Drop File Here area to define your data source.
  • Click on the Field Setup
  • Use the Theme Field drop-down list to specify the attribute you want to use as input into the hotspot process.
  • Use the Theme Name text box to specify a display name for your hotspot layer.
  • Use the Theme Classification drop-down list to specify a classification type (suggest Quantile 10 Groups as a starting point – this can be modified layer once you have a better idea of what you need).
  • Use the X (Longitude) Field drop-down list to specify the X attribute.
  • Use the Y (Latitude) Field drop-down list to specify the Y attribute.
  • Click on the Use Faster Rendering (less interactivity) check box to enable this option.
  • Click the Apply button – your point should render on screen.
  • Click on the Colors
  • Use the Type drop-down list to specify Custom.
  • Use the From, To, and Path controls to create a color sequence that goes from a light color to a dark color (e.g. Light red to Dark red).
  • Click on the Display Incident Emphasis check box to disable this option.
  • Click on the Evaluate point size in meters check box to enable this option.
  • Click Apply to apply these changes to your view.
  • Finally, use the Point size and Opacity sliders to interactively create your hotspot layer.
  • Once you are happy with your interpolation results, click the Apply button to persist the settings.
  • If you want to have multiple hotspot layers, go to the Chart Configuration tab and add additional themes here.


Note: This option works best when you have a collection of points that do not fall on top of one another spatially.
