Quick-Start Guide

Follow this step-by-step guide for a basic overview of the map functionality. The map can be accessed here.

Selecting Climate Scenario Parameters

First, we need to select a combination of parameters for the desired climate scenario.

Select a Climate Risk Measure: Start by choosing a climate metric of interest from the drop-down menu. These are climate hazards curated by our team that may pose potential risks to infrastructure. Choose a Scenario: Select one of the available climate scenarios (e.g., SSP126 for low emissions, SSP585 for high emissions). Scenarios help you understand potential futures under different climate action pathways. Select a Timescale: Use the timeline slider to choose the time period you are interested in, ranging from the 2020s to the 2100s for all months. This lets you see how climate risks evolve over time for particular months of the year. The example on the right illustrates a scenario where the selected measure is "% Area Covered by Burnt Vegetation"—used as a proxy for wildfire risk—under a moderate emissions projection for August in the 2060s.

Selecting Infrastructure Overlays

Second, we need to select the specific types of infrastructure we are interested in visualizing.

Select Infrastructure Overlays: On the right-hand side, you'll see a layers icon. Hover over it to reveal the available infrastructure overlays. In this example, the available infrastructure includes specific types of power grid data, which provides insight into its exposure under the selected climate scenario.

Download Data

From here, you can explore the map and your particular areas of interest visually to get a sense of asset exposure. You may wish to download the data to do an offline analysis, which can be done easily.

Draw a bounding box: On the right-hand side below the layers icon, there is a small black box icon. Clicking this will allow you to draw a box (or multiple boxes) over your area of interest. Click Download Data: On the control panel, click the Download Data button to download a CSV file. Data will be downloaded based on the layers and control panel values you have selected.

Methodology

This section provides an overview of how the Climate Risk Mapping Application is built and the methodology behind its calculations and data processing.

Data Sources

Climate Risk Lab Wiki tracks a broad source of physical risk datasets.

Below are datasets the Climate Risk Map application uses specifically.

Climate Data Sources

CMIP6 (Coupled Model Intercomparison Project Phase 6): The climate data used in this application is based on projections from CMIP6, an internationally recognized climate modeling initiative. CMIP6 provides multiple scenarios that represent different greenhouse gas emissions pathways, such as SSP126 (low emissions) and SSP585 (high emissions). This data allows for consistent and reliable analysis of future climate conditions.

Physical Asset Data Sources

OpenStreetMap (OSM): The infrastructure data, including power grids, facilities, and other critical infrastructure, is sourced from OpenStreetMap (OSM). OSM is a community-driven geospatial dataset that provides up-to-date, accurate information on physical assets around the world.

Data Processing

The data processing pipeline is divided into several key areas to ensure comprehensive analysis and reliability of results. Each aspect contributes to calculating the overall climate exposure of physical assets. As the project expands, more metrics will be added along with their methodology.

Physical Assets

The infrastructure data, such as power lines and facilities, is collected from OpenStreetMap (OSM). This data is then processed to extract the relevant infrastructure types and prepare them for use in the climate risk model. The infrastructure is cross-referenced to ensure accuracy and completeness, creating a reliable dataset of physical assets.

Infrastructure Validation Pipeline Coming Soon

Climate

Raw climate data is transformed to compute exposure metrics. For example, the percentage of area covered by burnt vegetation is calculated using CMIP6 data with a climatological mean of 10 years. This ensures that the climate data is properly standardized and comparable across different scenarios.

You can review the source code for climate data transformation here.

Exposure Metrics

Exposure metrics are calculated to assess the average climate risk within the boundary of each physical asset. This process involves zonal aggregation, where climate data is aggregated to each infrastructure unit. For instance, for power lines or facilities, the tool computes max exposure to a given risk metric, such as percentage of area covered by burnt vegetation.

You can review the source code for exposure metrics here.

Vulnerability Metrics

Coming Soon

Data Dictionary

The Climate Risk Map generally provides data at the asset level, along with associated properties and climate risk measures (exposure, vulnerability, etc...). Below are the initial fields available for download (subject to change).

osm_id: Integer – Unique identifier for each OpenStreetMap (OSM) object. This ID is crucial for referencing and linking OSM features with external datasets or within the OSM database.

osm_type: String – Indicates the category of the OSM feature. For power-related features, this type is typically “power,” representing different aspects of power infrastructure such as power lines or substations.

tags: JSON – A JSON-like field that stores metadata about the OSM feature. Tags may include identifiers, names, and other relevant information (e.g., {'ref': 'GCOU-CHJO-3', 'name': 'Grand Coulee-Chief Joseph No 3'}), providing important context about the feature.

geometry_wkt: String – The geometry of the OSM feature in Well-Known Text (WKT) format, which describes the shape and position of the feature using coordinates. For power lines, this typically defines a line geometry.

longitude: Float – Represents the east-west geographic centroid coordinate of the OSM feature, specifying its position on the Earth's surface.

latitude: Float – Represents the north-south geographic centroid coordinate of the OSM feature, specifying its position on the Earth's surface.

osm_subtype: String – A more specific type of OSM feature within the power category. For example, “line” could represent a power transmission line.

county_name: String – The name of the county where the OSM feature is located, helping to contextualize the feature’s geographic location at a local level.

city_name: String (optional) – The name of the city where the OSM feature is located, if applicable. This field may sometimes be empty if the feature is not within a defined city boundary.

ssp: Integer – Likely refers to the Shared Socioeconomic Pathway (SSP) scenario used in climate models. For example, an SSP value of 370 may refer to the SSP3-7.0 scenario, which models future socio-economic development and its impact on climate change.

month: Integer – Represents the month of the year in the dataset, where 1 stands for January, 2 for February, and so on. This is important for analyzing seasonal climate data.

decade: Integer – Represents the decade of the data (e.g., 2060), helping to differentiate climate data projected for different time periods.

climate_variable: String – Specifies the particular climate-related metric of interest (e.g., “burntFractionAll”). This indicates the environmental factor being assessed, such as temperature, precipitation, or other relevant variables.

climate_exposure: Float – Provides a numeric value indicating the degree of exposure the OSM feature has to the specified climate variable. For example, a value of 1.445 for "burntFractionAll" would represent 1.445%.
