GDACS Map Feed Standards
GDACS uses the RSS format as the main information standard. For maps, the format is extended to allow the linking of individual items with disaster events (alerts or emergencies).
There are currently two options: using the GLIDE number, or using a GDACS specific format. Both can be marked up using the gdacs namespace.
The GLIDE number is a unique disaster identifier, which is composed of a two letter event code, the year, a unique number and, optionally, the ISO3 country code. GLIDE numbers must be obtained from the GLIDE website.
The GLIDE number can be included in the feed as follows:
For compatibility, the gdacs namespace can be omitted.
GDACS specific format
In case a GLIDE number has not been created, an alternative way is to use GDACS specific information. Using the GDACS event type and identifier, maps can be linked to GDACS events. An example is:
The GDACS event id can be retrieved from the RSS feeds, APIs or other interfaces, both manually and programmatically. However, even if the eventid is not defined, including the eventtype will, along with the pubDate, provide valuable information to categorize and process maps from the feed.
