GeoPlanner and Scenario Planning

2023-04-10

Introduction

ArcGIS GeoPlanner is web-based online GIS platform.
Nearly everything you create in GeoPlanner can be used across ArcGIS products.
Provide service for evidence and performance-based planning and design.

GeoPlanner

Design and sketch

Quickly develop your designs using intuitive free-hand drawing or feature painting tools

GeoPlanner

Evaluate impacts and compare alternatives

Evaluation helps you understand the quality or performance of a plan by comparing it to the criteria modeled in suitability or active scenario layers and indicators.

GeoPlanner

Versatile dashboards

Display indicators and information in gauges, numeric values, and charts so you can quickly visualize and understand the effects of design decisions in real time.

Scenario Methodologies

Scenarios are representations of possible futures for one or more components of a system, particularly, in this assessment, for drivers of change in nature and nature’s benefits, including alternative policy or management options.

Exploratory scenarios

Intervention scenarios: “target-seeking” or “policy-screening”

Retrospective policy evaluation scenarios

Scenario Methodologies

Elements:

Scope: single issue, comprehensive, or problem–oriented (Event-driven)

Outcomes: awareness/knowledge exchange, vision/desired future, policy recommendation
Participation: Inform only/education, seeking feedback /knowledge sharing, joint fact finding/collaborative discovery

About the Scenario/Policy Development Process

different types of scenarios corresponding to the major phases of the policy cycle. The four major phases of the policy cycle: agenda setting, design, implementation, review.

In ‘exploratory scenarios’, the dashed lines represent different plausible futures, often based on storylines.

In ‘target-seeking scenarios’ (also known as ‘normative scenarios’), the diamond represents an agreed-upon future target and the colored dashed lines indicate scenarios that provide alternative pathways for reaching this target. In ‘policy-screening scenarios’ (also known as ‘ex-ante scenarios’), the dashed lines represent various policy options under consideration.

In ‘retrospective policy evaluation’ (also known as ‘ex-post evaluation’), the observed trajectory of a policy implemented in the past (solid black line) is compared to scenarios that would have achieved the intended target (dashed line).

About the Scenario Development Process

A structured way or process of thinking to prepare for a range of plausible futures based on a set of different “uncertainties”

In what ways might the community grow to achieve the desired vision?
