Python APIs for Horizon Data

horizonData = HorizonData("F:\\Data\\Segy\\Attributes\\bighorizon.xhz")

horizonDataCollection = HorizonDataCollection("F:\\Data\\Horzs\\Hith.dat")

Reading a collection using a given Ascii Mapping XML string (string divided into lines for easier reading):

XMLString='<Mapping>

  <FileDescriptor>

    <LineDescription delimiter="whitespace &amp; tab" endTag=""

      hasStartEndTag="false" noOfLinesToSkip="0" startTag=""/>

    <DefaultHeaderColumns>

      <Column name="INLINE" nameLocked="false" number="0"/>

      <Column name="XLINE" nameLocked="false" number="1"/>

    </DefaultHeaderColumns>

    <DefaultTimeColumn>

      <Column constantValue="0" isConstant="false" name="Time"

        nameLocked="false" number="2"/>

    </DefaultTimeColumn>

    <AttributeColumns/>

  </FileDescriptor>

</Mapping>'

horizonDataCollection = HorizonDataCollection("F:\\Data\\Horzs\\Hith.dat", XMLString)

chooser = HorizonDataChooser()

horizonDataCollection = chooser.getSelectedData()

NOTE: The chooser will always return a HorizonDataCollection.

horizonDataKeyNames = horizonData.getKeyNames();

horizonDataCollectionKeyNames = horizonDataCollection.getKeyNames();

Using this information, you can access specific key range information by using the following method:

dataInlineMin = horizonData.getKeyMinimum("INLINE")

dataInlineMax = horizonData.getKeyMaximum("INLINE")

dataCollectionInlineMin = horizonDataCollection.getKeyMinimum("INLINE")

dataCollectionInlineMax = horizonDataCollection.getKeyMaximum("INLINE")

horizons = horizonDataCollection.getAllHorizonData()

Retrieving a specific horizon data by name:

horizon = horizonDataCollection.getHorizonData("Hith")
