Painting is how you change a scenario’s land uses or building program in UrbanFootprint. You simply choose a new land use, in the form of ‘Building Types’ or ‘Place Types,’ and ‘paint’ the new use on selected parcels or blocks. UrbanFootprint does the work to quickly calculate and report the changes to population, jobs, housing units, and other key statistics.
The scenario creation and painting process facilitates quick development and testing of plan alternatives. The detailed attributes of the Building and Place Types ensure that UrbanFootprint is able ready to generate analytical outcomes for comparing the performance of land use scenarios (see Analyzing Scenarios for more on UrbanFootprint’s analysis modules).
Once you have created a new scenario, follow these steps to start painting:
Step 1 - Enable Build Mode
First, make sure you are in a new scenario instead of the “Base Scenario”.
Second, click on “Build” in the left hand Mode Bar.
Clicking on Build will open the right-hand Build pane and activate the “Painted Canvas” for the scenario. A layer must be activated to select features (geometries) in it.
The Build pane includes:
- Selection: A summary of the currently selected features, including a features count and the sum of developable acres in selected parcels or blocks.
- Type: Menus of available Place or Building Types.
- Paint: Button used to deploy Place or Building Types on to selected geometries. Once one or more features are selected and a Building or Place Type has been selected, click the Paint button to deploy the change.
- Revert: Button used to return selected geometries to the condition of the Base Canvas.
- Undo / Redo: Arrow buttons that undo or redo Paint and Revert actions.
Step 2 - Select features from the Painted Canvas layer
Select features on the Painted Canvas layer of the active scenario using one of two methods (or a combination of both):
Once one or more features are selected, the Build pane will summarize the selection.
Step 3 - Select a Building Type or Place Type
To open a Type palette: Click the Building or Place Type button in the Build pane.
To select a Type, click on it. To view a summary of key attributes for a Type (beyond the dwelling unit and employee densities per acre), click on the expand arrow.
Step 4 - Paint
Painting will be enabled once you have selected one or more features AND selected a Building or Place Type.
The Program section of the Build pane will then display a preview of the queued paint, enumerating the number of dwelling units, population, and employees that will be painted.
To paint, click the blue PAINT button (you can always undo it later).
The Program preview table includes:
- Base: the count of dwelling units, resident population, and employees in the base (existing conditions) canvas for the current selection.
- Net Change: the change (gain or loss) in dwelling units, population, and employment to be applied with the Paint action.
- Future: the resulting count of dwelling units, resident population, and employees that will applied once the Paint action is completed.
- Painted: the count of currently painted dwelling units, resident population, and employees already in the scenario that will be overridden by the current paint.
Revert to Base
The Revert to Base button is used to reset the one or more selections to the original base canvas land use and building program (dwelling units, population, and employment). You simply select the features on the map that you want to revert to the original base condition and click the Revert to Base button. This will reset the features to the original base canvas.
Note that selected features that have not been previously painted will be unaffected by the Revert to Base action - this is why in some cases the count of features shown in the Paint and Revert buttons will be different.
