I'm in the middle of initially deploying ArcGIS Urban and have been reviewing the Dashboard metrics graph and the space types metrics tab.
Although I basically understand the logic, it would be easier to fully understand if there was some documentation that simply described the overall logic and that for each metric too.
In addition, it would be VERY helpful to have a master list of the out-of-the-box factors used (CO2, water, etc.) from the primary source (net gsf, pop, jobs, etc.) AND the source of those factors. I need to validate the source of those factors and the source helps understand appropriateness for our city. See screenshots for examples.
If there is some documentation on the metrics logic and sources, that would be helpful. 🙂
Thank you,
Some 080423 Follow Up Questions and Comments and Resources from Response to an earlier Question:
089423 Follow-Up: Question on logic of Daily Trip Metric: In the "Metrics" tab of any of the Space Use Types, the calculation of Daily Trips (see screenshot) looks like it double counts, as it adds trips from net area to those of pop, households, and jobs. since pop, HH, and jobs are estimated from net area, this looks like double counting. Since pop and HH are generated from net area and represent the same source --residential development -- it looks like this formula partial double double counts.
I'm thinking I'm simply not understanding the logic, but the info in the metric tab shows Daily Trips = that from net area + pop + hh + jobs. Please explain, briefly, how this metric does not double count.
080423: I was directed to this recording of a webinar on metrics made earlier this year (available here), which does a great job of explaining the metrics logic and states that the metrics are NATIONAL averages from the American Planning Association, although no citation is provided. I goggled and BingChatted for it, but found nothing. Any chance the Esri Team could add the citation to the AGU documentation?
ALSO (080423 followup): Copying Response to an earlier Question on Metrics & Existing Conditions Data that addressed the topic of documentation, and may be useful to others:
This documentation topic covers configuring metrics including importing existing metric values on the Urban Model level. Existing metric values can be imported for any metric.
Whenever you create a plan, the metrics and existing metric values available on the Urban Model at creation time, are copied to that plan. For projects, only the metrics are copied.
The metrics (plans & projects) and the existing metric values (plans) can also be configured and edited on each plan and project individually. Any edits on metrics and existing metric values on the plan and project level don't impact the metrics and existing metric values configuration on the Urban Model level. There are also dedicated documentation pages for working with metrics on the plan and project level:
