Most O-D projects rely on pre-existing geographies. Get a shapefile of your geographies and ZIP them into a compressed folder. Click here to download a demo shapefile of all the ZIP Codes in Madison, which is in the supporting files for this tutorial.
You can use any type of geography in any SRID. Of course, if you’d like to draw your Zones, click “Draw New Zone” instead of uploading a shapefile. To follow along on this tutorial, click “Upload Shapefile” and select your shapefile from the browser.
Once you click “Open,” you will see a module that allows you to match the fields in your shapefile to StreetLight InSight’s fields. Because we are creating an Origin-Destination Matrix that analyzes Area Zones, remember to set the “Pass Through” option to “Always No.” (“Pass through” Zones usually designate road segments. For this Matrix, we’re interested in trips that start and end in Area Zones, not trips that pass through them.)
Once you press “continue” you’ll have a final chance to edit the names or borders of any Zones. To do so, click on the edit pencil icon next to the Zone before you save the Zone Set.
Now you can see your Zone Set saved in your Zone Set library. As long as you haven’t used it yet in a project, you can edit it by clicking the edit icon in the Actions column. You can also view it, duplicate it, download it as a shapefile, and more.
