Pacific Disaster Center (PDC)

The Pacific Disaster Center (PDC) tracks a wide range of natural and human made hazards viz. Tropical Cyclone, Earthquake, Flood, Landslides, Wildfire, Drought, Volcanic Eruptions etc to support disaster preparedness, response, and risk reduction efforts.

Collection: `pdc-events`

A STAC collection hold all the PDC events.

Endpoints for Extraction

To get the relevant PDC data, we use the following endpoints:

Get a list of Active Hazards: https://sentry.pdc.org/hp_srv/services/hazards/t/json/get_active_hazards
Get exposure list for each Hazard: https://sentry.pdc.org/hp_srv/services/hazard/{uuid}/exposure
Get exposure details for each exposure: https://sentry.pdc.org/hp_srv/services/hazard/{uuid}/exposure/{timestamp}

Data Schema

The PDCDataSource class when instantiated takes two parameters viz. source_url: str and data: Any.

The data parameter primarily takes a json object of the following format.

{
    "hazards_file_path": str,
    "exposure_timestamp": str,
    "uuid": str,
    "exposure_detail_file_path": str,
    "geojson_file_path": Optional[str]
}

Event Item

A PDC event will always produce an Event STAC Item. Here is a table with the fields that are mapped from the PDC event to the STAC event:

STAC field	PDC Field	Description
id	id	Unique Identifier
geometry	latitude, longitude	Geometric point using latitude and longitude
collection	`pdc-events`
bbox	longitude, latitude, longitude, latitude
datetime	create_Date
title	hazard_Name
description	description
roles	["source", "event"]	Default roles for event item
monty:country_codes	`country` field in the list `totalByCountry`	List of country iso3 are pulled from exposure endpoint by iterating `totalByCountry` field
monty:hazard_codes	type_ID	The hazard codes are generated using the mapping
asset.report	snc_url	Asset with the link to the PDC report

Hazard Item

A PDC event and the timestamp from exposure endpoint will ALWAYS produce one hazard STAC item. Here is a table with the STAC fields that are managed from the PDC event to the STAC hazard.

STAC field	PDC Field	Description
id	id	Unique Identifier
geometry	latitude, longitude	Geometric point using latitude and longitude
collection	`pdc-hazards`
bbox	longitude, latitude, longitude, latitude
datetime	create_Date
title	hazard_Name
description	description
roles	["source", "hazard"]	Default roles for hazard item
monty:country_codes	`country` field in the list `totalByCountry`	List of country iso3 are pulled from exposure endpoint by iterating `totalByCountry` field
monty:hazard_codes	type_ID	The hazard codes are generated using the mapping
asset.report	snc_url	Asset with the link to the PDC report
monty:hazard_detail

Impact item

The PDC events will produce multiple Impact STAC Items when impact related data is available through exposure endpoint.

The following table shows the mapping of PDC impact fields to STAC items.

STAC field	PDC Field	Description
id	id	Unique Identifier
geometry	latitude, longitude	Geometric point using latitude and longitude
collection	`pdc-impacts`
bbox	longitude, latitude, longitude, latitude
datetime	create_Date
title	hazard_Name
description	description
roles	["source", "impact"]	Default roles for impact item
monty:country_codes	`country` field in the list `totalByCountry`	List of country iso3 are pulled from exposure endpoint by iterating `totalByCountry` field
monty:hazard_codes	type_ID	The hazard codes are generated using the mapping
asset.report	snc_url	Asset with the link to the PDC report
[monty:impact_detail]	Impact items using different fields	Several impact items are created based on several fields available from the exposure endpoint
