Migrate from the query service to the seismic service

:::info Limited availability The features described in this section are currently only available to selected customers. :::

The guide helps you migrate from the query v0 service to the seismic v1 service. It provides translations for the v0 API methods. The document suggests solutions if there's no direct translation or methods are deprecated.

These concepts have changed in the seismic v1 service:

  • SeismicStore and Seismic objects. The SeismicStore is an object that represents an ingested SEG-Y file but isn't directly available as part of the entitlement. The Seismic object is a cutout of a SeismicStore and composes an entitlement. Queries no longer reference files directly and use either the Seismic or the SeismicStore objects instead.

  • Search, Get, and List queries. The Seismic API v1 combines the Search, Get, and List metadata queries into a single generic Search query. This query accepts a search specification. For example, searching by an identifier or a unique name will show the results of the Get query, and an empty search will behave like the List query.

  • StreamTraces endpoint. The Seismic API v1 combines many trace access endpoints into a single, more flexible com.cognite.seismic.v1.SeismicService.StreamTraces endpoint. By changing the query parameters slightly, you can produce similar results to many of the methods the endpoint replaces.

:::info To learn more about the Seismic API v1, see the documentation. :::

Metadata queries and payload examples

Metadata queries consist of com.cognite.seismic.Query. + MethodName = com.cognite.seismic.Query.MethodName, for example, com.cognite.seismic.Query.GetSurvey. See below for changed and deprecated methods.

Changed methods

GetSurvey

Use com.cognite.seismic.v1.SeismicService.SearchSurveys.

Payload example

v0
com.cognite.seismic.Query/GetSurvey
{
  "survey": {
    "name": "some_name"
  }
}
v1
com.cognite.seismic.v1.SeismicAPI/SearchSurveys
{
  "surveys": {
    "name": "some_name"
  }
}

ListSurveys

Use com.cognite.seismic.v1.SeismicService.SearchSurveys without a surveys search specification.

Payload example

v0
com.cognite.seismic.Query/ListSurveys
{
  "include_metadata": true
}
v1
com.cognite.seismic.v1.SeismicAPI/SearchSurveys
{
  "include_metadata": true
}

ListFiles

Use com.cognite.seismic.v1.SeismicService.SearchFiles without the spec search specification.

SearchSurveys

Use com.cognite.seismic.v1.SeismicService.SearchSurveys.

GetFile

Use com.cognite.seismic.v1.SeismicService.SearchFiles with the spec containing the identifier for the file.

Payload example

v0
com.cognite.seismic.Query/GetFile
{
  "file": {
    "name": "some_name"
  }
}
v1
com.cognite.seismic.v1.SeismicAPI/SearchFiles
{
  "spec": {
    "name": "some_name"
  }
}

GetBinaryHeader

Fetch the original SEG-Y binary headers from com.cognite.seismic.v1.SeismicService.SearchSeismicStores by setting include_headers to true.

Payload example

v0
com.cognite.seismic.Query/GetBinaryHeader

  }
}
v1
com.cognite.seismic.v1.SeismicAPI/SearchSeismicStores
{
  "seismic_store": {
    "name": "some_name"
  },
  "include_headers": true
}

:::info Info Seismic objects also have binary headers. By default, the objects inherit the headers from the original file, but data managers can override them. You can fetch the headers from com.cognite.seismic.v1.SeismicService.SearchSeismics. :::

    "name": "some_name"
  },
  "in_wkt": true
