GLIDE

GLIDE is a globally common Unique ID code for disasters and emergencies. It is a unique identifier that is assigned to each disaster event by the Asian Disaster Reduction Center (ADRC).

Collection: glide-events

A STAC collection hold all the GLIDE events. An example of the GLIDE collection is here.

Data

Accessible data is a set of GLIDE entries. Each entry is a disaster event. The event data list is available in the form of a array called "glideset" via the API endpoint https://www.glidenumber.net/glide/jsonglideset.jsp.

Important

Despite what's described in the documentation, the API endpoint https://www.glidenumber.net/glide/jsonglideset.jsp cannot retrieve individual events. It is necessary to add other filter to narrow down the search (e.g. https://www.glidenumber.net/glide/jsonglideset.jsp?level1=ESP&fromyear=2024&toyear=2024&events=FL&number=2024-000199)

Event Item

A GLIDE event and episode will ALWAYS produce an event STAC item as in the example for the flood in Spain.

The event URL of the jsonglideset API endpoint is stored in the links field of the STAC item with the via relation.

Here is a table with the fields that are mapped from the GDACS event to the STAC event:

STAC field GLIDE field Description
id event + number + geocode Unique identifier for the event
geometry longitude + latitude as geojson POINT Geometry of the event (POINT)
collection glide-events The collection for GDACS events
title humaran readable from event, location, year, month, day Name of the event
description comments Description of the event. HTML description should be privileged over plain text description and translated to markdown
datetime year + month + date Date and time of the event converted in UTC ISO 8601 format
monty:country_codes[0] geocode ISO3 code of the country where the event occurred. Keywords shall also contain the human readable country name
monty:country_codes[1..*] geocode List of ISO3 codes of the other countries affected by the event
monty:hazard_codes event List of hazard codes converted following the GLIDE event type to Hazard profile mapping

Hazard Item

A GLIDE event and episode will ALWAYS produce one hazard STAC item as in the example for the flood in Spain.

Here is a table with the STAC fields that are mapped from the GDACS event to the STAC hazard:

STAC field GLIDE field Description
id event + number + geocode Unique identifier for the event
geometry longitude + latitude as geojson POINT Geometry of the event (POINT)
collection glide-events The collection for GDACS events
title humaran readable from event, location, year, month, day Name of the event
description comments Description of the event. HTML description should be privileged over plain text description and translated to markdown
datetime year + month + date Date and time of the event converted in UTC ISO 8601 format
monty:country_codes[0] geocode ISO3 code of the country where the event occurred. Keywords shall also contain the human readable country name
monty:country_codes[1..*] geocode List of ISO3 codes of the other countries affected by the event
monty:hazard_codes event List of hazard codes converted following the GLIDE event type to Hazard profile mapping
asset.report https://www.glidenumber.net/glide/public/search/details.jsp?glide= + docid Asset with the link to the GDACS report
via link in [links] source url Link to the GDACS event details page
monty:hazard_detail ? Detailed description of the hazard (more details in next section)

Hazard Detail

The hazard_detail field is a JSON object that contains the detailed information about the hazard. The object is a mapping of the hazard codes to the detailed information. The detailed information is a JSON object with the following fields:

STAC field GLIDE field Description
clusters event Hazard clusters codes
severity_unit glide GLIDE alert level
severity_value magnitude Magnitude of the event
Mapping from GLIDE event type to Hazard profile

There is not straightforward mapping from the GLIDE event type to the hazard profile. The current mapping only considers setting the clusters field as the following:

GLIDE event type Hazard profile cluster (2025) Hazard Profile codes (2025)
CW (Cold Wave) MH-TEMP MH0502 (Cold Wave)
CE (Complex Emergency) SO-CONFLICT SO0102 (NIAC)
DR (Drought) MH-PRECIP MH0401 (Drought)
EQ (Earthquake) GEO-SEIS GH0101 (Earthquake)
EP (Epidemic) BIO-INFDIS Multiple codes
EC (Extratropical Cyclone) MH-WIND MH0307 (Extra-tropical Cyclone)
FR (Fire) ENV-DEG EN0205 (Wildfires)
FF (Flash Flood) MH-WATER MH0603 (Flash Flooding)
FL (Flood) MH-WATER MH0600 (Flooding chapeau)
HT (Heat Wave) MH-TEMP MH0501 (Heatwave)
IN (Insect Infestation) BIO-INSECT BI0401 (Insect Pest Infestations)
LS (Land Slide) GEO-GROUND GH0300 (Gravitational Mass Movement)

More specific hazard codes can be added to the codes field following the characteristics of the event.
