NCEDC Web Services
URL change:
The NCEDC's web service interfaces are in transition to a new URL: service.ncedc.org
The following NCEDC web services are moving to a new naming convention:
- ws-sacpz is moving to service.ncedc.org/ncedcws/sacpz/1
- ws-resp is moving to service.ncedc.org/ncedcws/resp/1
- ws-dataless is moving to service.ncedc.org/ncedcws/dataless/1
FDSN web services implementation:
The following web services are effectively deprecated and replaced by their FDSN equivalent:
- ws-dataselect & ws-bulkdataselect are both replaced by fdsnws-dataselect
- ws-station is replaced by fdsnws-station
- ws-event is replaced by fdsnws-event
- ws-availability is replaced by fdsnws-station. Equivalent information is included by specifying includeavailability=true
The ws-sacpz web service (http://service.ncedc.org/ncedcws/sacpz/1) provides access to poles and zeros information in SAC ASCII format. Users can query for channel response by network, station, channel, location and time.
The ws-resp web service (http://service.ncedc.org/ncedcws/resp/1) provides access to channel response information in the SEED RESP format (as used by evalresp). Users can query for channel response by network, station, channel, location and time.
The ws-dataless web service (http://service.ncedc.org/ncedcws/dataless/1) provides access to channel response information in the Dataless SEED format. Users can query for channel response by network, station, channel, location and time.
The ws-station web service (http://www.ncedc.org/ws/station) provides access to station metadata in the NCEDC database. The results are returned in XML format using the
StationXML schema. Users can query for station metadata by network, station,
channel, location, time and other search criteria and request results at multiple
levels (station, channel, response).
The ws-availability web service (http://www.ncedc.org/ws/availability) returns information about what time series data is available at the NCEDC. Users can query for inventory information by network, station, channel, location, time and other search criteria. Data can be returned in three different formats: ws-bulkdataselect input, ws-dataselect query parameters and XML.
The ws-dataselect web service (http://www.ncedc.org/ws/dataselect) returns a single channel of time series data in miniSEED format. With this service you specify network, station, location, channel and a time range and the service returns miniSEED.
ws-dataselect is part of the ICAB system. Data that it extracts from the NCEDC repositories can be passed to other ICAB services or can be returned directly.
The ws-bulkdataselect web service (http://www.ncedc.org/ws/bulkdataselect) returns multiple channels of time series data in miniSEED format for specified time ranges. With this service you specify a list of selections composed of network, station, location, channel, start-time and end-time and the service streams back the selected raw waveform data.
ws-bulkdataselect can handle very large selections and can be easily driven by command line programs such as wget, curl or similiar utilities.
