Package: georss-ign-sismologia-client
python-georss-ign-sismologia-clientThis library provides convenient access to theInstituto Geográfico Nacional Sismología (Earthquakes) Feedfeed.Installationpip install georss-ign-sismologia-clientUsageSee below for examples of how this library can be used for particular GeoRSS
feeds. After instantiating a particular class and supply the required
parameters, you can callupdateto retrieve the feed data. The return value
will be a tuple of a status code and the actual data in the form of a list of
feed entries specific to the selected feed.Status CodesUPDATE_OK: Update went fine and data was retrieved. The library may still return empty data, for example because no entries fulfilled the filter criteria.UPDATE_OK_NO_DATA: Update went fine but no data was retrieved, for example because the server indicated that there was not update since the last request.UPDATE_ERROR: Something went wrong during the updateSupported FiltersFilterDescriptionRadiusfilter_radiusRadius in kilometers around the home coordinates in which events from feed are included.Minimum Magnitudefilter_minimum_magnitudeMinimum magnitude as float value. Only events with a magnitude equal or above this value are included.Examplefromgeorss_ign_sismologia_clientimportIgnSismologiaFeed# Home Coordinates: Latitude: 40.38, Longitude: -3.72# Filter radius: 200 km# Filter minimum magnitude: 3.0feed=IgnSismologiaFeed((40.38,-3.72),filter_radius=200,filter_minimum_magnitude=3.0)status,entries=feed.update()Feed entry propertiesEach feed entry is populated with the following properties - subject to
availability in GeoRSS feed:NameDescriptiongeometryAll geometry details of this entry.coordinatesBest coordinates (latitude, longitude) of this entry.external_idExternal id of this entry.titleTitle of this entry with date and time of the event.attributionAttribution of the feed.distance_to_homeDistance in km of this entry to the home coordinates.descriptionTextual description of this entry.publishedPublished date of this entry.magnitudeMagnitude value of this entry.regionRegion in formation of this entry.image_urlImage URL showing a map of the entry.Feed ManagerThe Feed Manager helps managing feed updates over time, by notifying the
consumer of the feed about new feed entries, updates and removed entries
compared to the last feed update.If the current feed update is the first one, then all feed entries will be
reported as new. The feed manager will keep track of all feed entries'
external IDs that it has successfully processed.If the current feed update is not the first one, then the feed manager will
produce three sets:Feed entries that were not in the previous feed update but are in the
current feed update will be reported as new.Feed entries that were in the previous feed update and are still in the
current feed update will be reported as to be updated.Feed entries that were in the previous feed update but are not in the
current feed update will be reported to be removed.If the current update fails, then all feed entries processed in the previous
feed update will be reported to be removed.After a successful update from the feed, the feed manager will provide two
different dates:last_updatewill be the timestamp of the last successful update from the
feed. This date may be useful if the consumer of this library wants to
treat intermittent errors from feed updates differently.last_timestampwill be the latest timestamp extracted from the feed data.
This requires that the underlying feed data actually contains a suitable
date. This date may be useful if the consumer of this library wants to
process feed entries differently if they haven't actually been updated.
