Use the 360 Setup tab to access all of the tools and information you need when setting up an analysis. When thinking about an analysis A Scenario 360 analysis is a means of evaluating an issue or opportunity, including alternative approaches ("scenarios"), community input, outcome analysis, and decisions. In Scenario 360, an analysis provides the overall framework for a project. It includes all of the map data, scenarios, calculations, and indicators for the various alternatives you may consider when evaluating an issue or opportunity., you can think of it as something with inputs, calculations, and outputs - as displayed in the Work Flow view. Follow the steps suggested by the flow chart to set up your analysis.
Data are inputs that consist of map layers and tables.
Assumptions An assumption is a value that is used as input to an analysis and it is often changeable. Assumptions apply to an entire scenario. For example, your assumptions about water consumption per household will impact the indicator for total water consumption for a scenario. Assumptions can also be a way to express subjective inputs, such as how much weighting to give to a particular community value like open space or economic development. Output values that depend on a particular assumption are automatically updated when the assumption is changed and you click the Apply button. are user-defined inputs used in an analysis. They are often changeable.
An analysis contains one or more alternative scenarios An analysis contains one or more scenarios. Each scenario represents a different decision-making alternative. The first scenario in your analysis is called the base scenario. It can represent existing conditions, the primary proposal under evaluation, business as usual, or the first of several alternatives you wish to compare in an analysis.. Scenarios are alternative viewpoints of an analysis. Each scenario in a given analysis has distinct input settings and outputs, but identical calculation rules.
Attributes 1. A piece of information describing a map feature. The attributes of a census tract, for example, might include its area, population, and average per capita income. 2. A characteristic of a geographic feature described by numbers, characters, images, and CAD drawings, typically stored in tabular format and linked to the feature by a user-assigned identifier. For example, the attributes of a well might include depth and gallons per minute. 3. A column in a table. are properties or characteristics of map features. A dynamic attribute A dynamic attribute is an attribute that is automatically updated as changes are made in the analysis. For example, a proposed road layer may contain dynamic attributes for length, pavement type, intersecting slopes, and construction costs. As each new road segment is added or modified, each of these dynamic attributes will be updated automatically. A formula is associated with each dynamic attribute that specifies how the attribute is calculated. is an attribute that is automatically or manually updated as changes are made in the analysis using the unique capabilities of Scenario 360.
Indicators Indicators are the impact or performance measures that help people choose alternatives that best match their objectives or desired outcomes. An indicator is a calculated value that represents the impacts or outcomes of a scenario. Indicator results are automatically recalculated as you experiment with alternatives and the results can be displayed in a chart. Indicators apply to an entire scenario. An indicator might be used to evaluate costs, revenues, average household size, "community benefit", or total daily auto trips. are impact or performance measures. They are calculated output values that can reference data sets anywhere in the scenario. They are used to provide an overall measurement for a scenario (as opposed to an attribute, which provides the individual characteristic of a map feature).
Alerts An alert may be associated with an assumption, a dynamic attribute, or an indicator. An alert is used to monitor values during analysis and report if specific conditions occur. Alerts may be displayed as a chart with (colored) target bars, an alert message, or as a feature symbol on a map. are thresholds, defined by you, that are associated with particular assumptions, dynamic attributes, or indicators. Alerts let you know if a scenario value is outside of a specification.
Charts Values for indicators and assumptions are automatically calculated as you experiment with alternatives and the results can be displayed graphically in a chart. Charts are dynamically linked to assumptions and indicators. As changes are made in the analysis, chart displays will update automatically to reflect analysis results. are a graphical way of looking at indicators and assumptions.
Reports summarize the inputs, calculations, and outputs of one or more scenarios.
You can use the Work Flow, Tree, or Category view when setting up your analysis.
