The dashboards in the plan and project editors show metric values of the plan scenarios or project scenarios, respectively. In the data manager, you can configure metrics and define how they are calculated in plans. In plans, metrics are calculated based on your proposed development (zoning plan) or proposed land-use regulation (land-use plan). In projects, you must input the metric values manually.
ArcGIS Urban comes with two versions of metrics: old and new. Compared to the old metrics, the new metrics offer more capabilities, such as additional operators (multiply and divide), measurement metrics (for example parcel area and building footprint area), and the option to choose on which resolution to calculate a metric. In plans, it is recommended to use the new metrics. The old metrics will be deprecated and eventually removed in the future. You can decide per plan if you want to use the old or the new metrics. See Switch between old and new metrics to learn more. You can also convert the old metrics to the new metrics. See Convert old to new metrics to learn more.
Note:
While you can use the new metrics in plans, projects still use the old metrics.
Use the Metrics (new) option in the Dashboard section of the data manager to define and edit the new metrics and the Metrics option to configure the old metrics. Use the Existing metric values option to import existing metric values for old and new metrics.
See Work with the dashboard in plans and Work with the dashboard in projects to learn more about analyzing metrics in the dashboard.

Understanding types of metrics
Urban includes different types of metrics. You can identify the type of a metric by the icon to the left of the metric name. The following types exist:
- Measurement —A built-in metric that represents a measurement. For example, space area or building height. Use it as an input to calculate new metrics with operators or to show the measurement itself on the dashboard.
- Space use type parameter —A metric that allows you to add a parameter for each space use type. Use it as an input to calculate new metrics with operators.
- Variable —A number that you can use as an input to calculate new metrics with operators.
- Operators—Operators that allow you to calculate metrics based on existing ones. The following operators are available:
- Add
- Subtract
- Multiply
- Divide
- Round
- Compound metric —A built-in metric that is made up of multiple metrics. When you add a compound metric to the graph, multiple metrics, connected with an operator, are added.
See Add a metric to learn more details about the different metrics that are available in Urban.
Understanding metric resolution and aggregation
The metric Resolution determines the level at which the metric is calculated. You can identify the metric resolution by the icon to the right of the metric name when exploring the metric graph. The following resolutions exist, ordered from higher to lower resolution:
- Space —The metric is calculated for each building space, surface, and ground.
- Building —The metric is calculated for each building.
- Parcel —The metric is calculated for each parcel.
- Study area or selection —The metric is calculated for the parcel selection or for the study area, if no parcel is selected.
See Configure a metric to learn more about metric resolution.

See Understanding types of metrics to learn more about what types of metrics are available inUrban.
- Open the metrics (new) page.
- From the drop-down menus in the header, click the metric you want to add to the graph. The following metrics are available:
- Spaces—Built-in metrics of building spaces, surfaces, and ground:
- Space area —Total area of each building space and surface.
- Net space area —Net area of each building space and surface. The net area is the total area multiplied by the net area factor of the space-use type.
- Dwelling units —Number of dwelling units in each space. See Validate using the building regulation side panel to learn how the number of dwelling units is calculated per space-use type within a building. This number is evenly distributed to the spaces of the same space-use type in the building.
- Space use type parameter —A metric that allows you to add a parameter to each space-use type to be used in further calculation.
- Buildings—Built-in metrics of buildings:
- Building footprint area —Total footprint area of each building.
- Building gross floor area —Gross floor area (GFA) of each building. Only spaces that count toward GFA/FAR are included. See Edit building spaces to learn how you can include or exclude a space from GFA in the plan editor.
- Building height —Height of each building.
- Building number of floors —Number of floors in each building.
- Building substructure depth —Substructure (below ground) depth of each building.
- Building substructure floors —Number of substructure (below ground) floors in each building.

Configure a metric
You can configure the following metric types:
- Operators
- Space use type parameters
- Variables
To configure a metric, complete the following steps:
- Open the metrics (new) page.
- Click the metric in the graph that you want to configure.
The metric configuration side panel appears.
- Optionally, provide a name and description.
Metrics without a name cannot be shown on the dashboard and cannot have existing metric values.
- Continue with the type-specific metric configurations:
- Configure an operator metric.
- Configure a space use type parameter metric.
- Configure a variable metric.
Tip:
You can also configure space use type parameters in the space use type dialog box. See Manage space-use types to learn more.
Configure an operator metric
To configure an operator metric, complete the following steps:
- Click a metric in the graph to open the metric configuration side panel and configure a name and a description.
- Configure the operator metric inputs. You can select the inputs in the metric configuration side panel or connect the metrics in the metric graph:
- Select metric inputs in the configuration side panel—In the Calculation section, select one or multiple metrics from the Select metric drop-down lists to add them as inputs to the calculation.
- Connect the metrics in the metric graph—In the metric graph, browse to the metric you want to use as an input. Hover over the metric output circle next to the resolution icon. Click and drag the pointer to the metric input circle next to the operator icon of the target metric.
Note:
- The number of required and allowed inputs depends on the operator you selected:
- Round—Requires exactly one input.
- Subtract and Divide require exactly two inputs.
- Add and Multiply can have one or more inputs.
- For subtractions and divisions, the order of the inputs influences the calculation:
- Subtract—The lower metric (subtrahend) is subtracted from the upper metric (minuend).
- Divide—The upper metric (dividend) is divided by the lower metric (divisor).
- For the Round operator, configure the Rounding method:
- Nearest—The metric value is rounded to the nearest whole number.
- Up—The metric value is rounded up to the next larger whole number.
- Down—The metric value is rounded down to the next smaller whole number.
- Optionally, provide a unit for the Unit parameter. You can choose one of the predefined units or create your own:
- Predefined unit—Select a unit from the drop-down list.
- Custom unit—Select Custom in the drop-down list. Below the drop-down menu, click the Add unit dividend button to select and add a unit dividend and click the Add unit divisor button to select and add a unit divisor. For example, to create the unit "volume per day", add "volume" as a dividend, and "day" as a divisor.
Note:
- The unit of an operator metric must be compatible with the units of its inputs. For example, when using the Add operator, all inputs must have the same unit. If the units don't match, the calculation is not possible and an error message appears.
- You cannot change the unit of a metric that has existing metric values.
- The Round operator only supports the following units: number, days, and angle.
- Configure the metric Resolution. The metric resolution determines the level at which the metric is calculated. Choose one of the following resolutions, ordered from higher to lower resolution:
- Space —The metric is calculated for each building space, surface, and ground.
- Building —The metric is calculated for each building.
- Parcel —The metric is calculated for each parcel.
- Study area or selection —The metric is calculated for the parcel selection or for the study area, if no parcel is selected.
When choosing a metric resolution, consider the following:- The metric cannot be used at resolutions higher than its own. For example, a metric calculated at the building resolution cannot be used as an input for a metric calculated at the space resolution. If the resolutions don't match, the calculation is not possible and an error message appears.
- The metric can be used at lower resolutions, if aggregation is enabled (set to Sum). Learn more about aggregation in the next step.
- The optimal resolution depends on the use case:
- Use the highest possible resolution to keep the metric calculation as granular as possible.
- When you round a metric, there are cases in which choosing the highest possible resolution is not recommended. For example, it is better to round population at the building level rather than the spaces level, because people can live on multiple spaces (floors).
- Only building spaces are aggregated to the building resolution; surfaces and ground are not.
- Configure the metric Aggregation method. The aggregation determines whether the metric can be aggregated to lower resolutions in the graph and dashboard. Choose one of the following aggregation methods:
- Sum—The metric values are summed to lower resolutions.
- None—The metric values cannot be aggregated to lower resolutions.
When choosing an aggregation method, consider the following:- Metrics in which the aggregation method is set to None cannot be used as inputs to lower-resolution metrics. For example, a metric calculated at the building resolution with aggregation disabled cannot be used as an input for a metric calculated at the parcel resolution. If the resolution and aggregation settings don't match, the calculation is not possible and an error message appears.
- Values of metrics in which aggregation is set to None and the aggregation is higher than Parcel cannot be displayed on the plan editor dashboard, since this requires aggregation to either parcels or the study area. In this case, a warning appears in the dashboard.
- Metrics in which aggregation is set to None cannot have existing metric values.
- Setting the aggregation method to None is only recommended in a few cases. For example, when you calculate a ratio, such as the floor area ratio (FAR). If you calculate FAR (gross floor area divided by parcel area), it is recommended that you set the aggregation to None, because summing FAR of multiple parcels would lead to incorrect results.
Note:
There are a few measurement metrics (building height, building number of floors, building substructure depth, and building substructure floors) that use the aggregation method Maximum. This aggregation method cannot be changed and is currently not available in other metrics.
Configure a space use type parameter metric
To configure a space use type parameter metric, complete the following steps:
- Click a metric in the graph to open the metric configuration side panel and configure a name and a description.
- In the Space use type parameters section, click Add and select the space-use type you want to add a parameter to.
The space-use type is added to the table.
- Click the Edit button and add a space-use type parameter.
To remove a space-use type from the table, click the Delete button .
- Optionally, provide a unit for the Unit parameter. You can choose one of the predefined units or create your own:
- Predefined unit—Select a unit from the drop-down list.
- Custom unit—Select Custom in the drop-down list. Below the drop-down menu, click the Add unit dividend button to select and add a unit dividend and click the Add unit divisor button to select and add a unit divisor. For example, to create the unit "volume per day", add "volume" as a dividend, and "day" as a divisor.
Note:
If you change the unit, the values of already configured space-use type parameters might change. Ensure the values are still correct.
Configure a variable metric
To configure a variable metric, complete the following steps:
- Click a metric in the graph to open the metric configuration side panel and configure a name and a description.
- Use the Value input field to configure a variable value.
- Optionally, provide a unit for the Unit parameter. You can choose one of the predefined units or create your own:
- Predefined unit—Select a unit from the drop-down list.
- Custom unit—Select Custom in the drop-down list. Below the drop-down menu, click the Add unit dividend button to select and add a unit dividend and click the Add unit divisor button to select and add a unit divisor. For example, to create the unit "volume per day", add "volume" as a dividend, and "day" as a divisor.
Note:
If you change the unit, the variable value might change. Ensure the value is still correct.
Delete metrics
To delete one or multiple metrics, complete the following steps. You cannot delete metrics that have existing metric values. Delete the existing metric values first in this case.
- Open the metrics (new) page.
- Delete one or multiple metrics.
- Delete a single metric—Select the metric and click the Delete button at the bottom of the metric configuration side panel.
- Delete multiple metrics (Shift selection)—Select multiple metrics by pressing the Shift key while clicking the metric. Then click the Delete button at the lower right or press the Delete key.
- Delete multiple metrics (rectangle selection)—Select multiple metrics by pressing the Alt key and drawing a selection box around metrics. Then click the Delete button at the lower right or press the Delete key.
All selected metrics and their connections are deleted. Metrics that have existing metric values remain on the graph. Delete the existing metric values first. Then delete the metric.
Convert old to new metrics
To convert your old metrics to new metrics, complete the following steps:
Note:
- You can only convert your old metrics, if your new metric graph is empty. Consider deleting all new metrics first. See Delete metrics to learn how to delete new metrics.
- Projects are still using old metrics for now. Continue to use the old metrics graph for projects, even if you converted the old metrics graph.
- To use new metrics in your plans, you must enable them in the plan dashboard. See Edit the dashboard to learn more.
- Open the metrics (new) page.
The New metrics dialog box automatically appears if you have old metrics defined and the new metric graph is empty.
- Click OK to convert your old metrics.
The converted metric graph appears.
Note:
- The converted metrics graph includes more metrics than the old graph, because old metric connections are converted to new metrics. If there was no optional chart label defined on the old metric connection, the newly introduced metric is missing a name. Consider adding a name to the metric to show it on the dashboard or add existing metric values.
- New metrics don't support optional chart labels anymore and in some cases are dropped during conversion. This can influence the new metrics dashboard. Consider reviewing the dashboard after converting metrics if you were using optional chart labels.
- Metrics are rounded differently in the new graph compared to the old graph. This can lead to slightly different metric values. The old metrics were rounding metric values per space-use type per parcel. Converted new metrics are by default rounding per space.
- The layout of the old metrics graph is not preserved.
Metrics (old)
In the data manager you can define and edit old metrics.
Note:
ArcGIS Urban comes with two versions of metrics: old and new. Compared to the old metrics, the new metrics offer more capabilities, such as additional operators (multiply and divide), measurement metrics (for example parcel area and building footprint area), and the option to choose on which resolution to calculate a metric. In plans, it is recommended to use the new metrics, since the old metrics will be deprecated in the future. See Metrics (new) to learn more.Explore metrics

- Metrics where aggregation is disabled
- In the Item step, search for the ArcGIS Online layer that contains the existing metric values. Click the layer and click Next to continue.
- You can import existing metric values from point, polygon, and polyline feature layers.
- The point features representing the existing metric values are converted to the coordinate system of the urban model if the coordinate systems don't match.
- In the Sublayer step, select a sublayer, and click Next to continue.
- In the Fields step, use the Fields in source drop-down menu to configure the source field that contains the existing metric values.
- Optionally, use the Units in source drop-down menu to configure the units in the existing data source.
- If you are importing values from a hosted feature layer that does not contain point features, choose how line features or polygon features with existing values will be converted to point features.
- Centroids—Import points as centroids of the input geometry. If the centroid is outside the geometry, a reasonable point inside the geometry is used instead.
- Equally distanced points—Distribute the source value to equidistant points along a grid. No point is created if its value is 0.
- In the Fields step, click Next.
- In the Validation step, review invalid features in the Errors table if errors are detected. Correct the errors in the source data and click Refresh. If all features are valid, click Next or wait for five seconds to start the import.
- In the Import step, all features are imported. Click Close to close the dialog box.
Note:
In the Validation step, the number of features validated in the data source is shown, whereas in the Import step, the number of features imported to the urban database is displayed. The numbers can differ if you import existing metric values using the Equally distanced points import option from a hosted feature layer containing line features or polygon features.
Note:
- For metrics that are configured to be rounded to whole numbers, existing metric values are rounded per data point. See the Configure a metric section above to learn more about metric rounding.
- Existing metric values of aggregated metrics cannot be calculated from the existing metric values of the source metrics involved. Add dedicated existing metric values for aggregated metrics.
