class Segy |
| |
Base class that contains the SEGY header and all the traces
http://seg.org/publications/tech-stand/
Then look at segy rev 0 and rev 1
|
| |
Methods defined here:
- __init__(self, filename=None, drivername='segy_drv_rev1', verbosity=0)
- Open up a segy file for reading using mmap for speed.
filename - name of the segy file to read
drivername - what format of segy does this file need.
FIX: Eventually a value of None should allow you to have this
code identify the version.
verbosity - how much spewage
- getHeader(self)
- getNumberOfTraces(self)
- FIX: deal with variable length traces
- getRawTrace(self, traceNumber)
- Return a block of bytes for a trace including header and data
- getTraceData(self, traceNumber=1)
- return a list of samples
FIX: cope with variable length traces
- getTraceDataSize(self, traceNumber=1)
- FIX: handle variable length traces
- getTraceHdr(self, traceNumber=1)
- getTraceSize(self, traceNumber=1)
- returns the number of bytes for the particular trace
fix: cope with variable length traces
- getTraceStart(self, traceNumber)
- Return the starting offset in a file of a particular trace
FIX: cope with extended text headers and variable length traces
- writeTraceToFile(self, filename='default.dat', traceNumber=1)
- Write out pairs of samplenumber and value to a file

class SegyHdr |
| |
class for reading segy seismic file header
http://seg.org/publications/tech-stand/
Then look at segy rev 0 and rev 1
|
| |
Methods defined here:
- __init__(self, mmapData=None, size=None, filename=None, drv=None)
- Open up a segy file for reading using mmap for speed.
- getBinEntry(self, fieldName)
- Retrieve the value from one of the binary header entries by name
- getEntireRawHdr(self)
- Return a block of memory containing all of the text, binary, and extended headers
- getTextFileBlock(self)
- Return the raw text header block. Could be either ebcdic or ascii
- getTextHeaderField(self, fieldName)
- BROKEN
e.g.:
C2 LINE:5t6 AREA:Goleta
- getTextHeaderLine(self, lineNumber)
- Return the string for the line number
- getTextTranslateValue(self, key, val)
- Lookup in the driver what the translation for a value should be
e.g. 'SampleFormat' of 1 will return:
4-byte IBM floating point
- hasR1TextFileHeader(self)
- Turn True if it has a R1 header with C1..C40 sections as ASCII
- printBinaryHeaders(self, shortList=False, filename=None)
- Dump all header into to stdout
shortList - use the shorter list provided by the driver. most interesting fields
- sqlInsert(self, filename, specificKeys=None, table='segyFile')
- Build an SQL string to INSERT the values for the current file
SEE CREATE...
FIX: CorrelatedTraces and BinGainRecovered are bools, but I treat them as ints
FIX: maybe check self.drv if this function is provided by the driver.
|
class SegyTraceHdr |
| |
Handle one trace in a segy file.
|
| |
Methods defined here:
- __init__(self, segyHdr, startOffset, mmapData=None, drv=None)
- Load up a trace from an mmap'ed data file by jumping to the startOffset
- getHeader(self, fieldName)
- Return the interpreted value for a trace header field
Should know about IBM floats but does not!
- getTextTranslateValue(self, key, val)
- Lookup in the driver what the translation for a value should be
e.g. 'TraceId'
- printHeader(self, shortList=False, filename=None, traceNum=None)
- Dump all trace header info to stdout
shortList - use the driver specified shorter list of more interesting fields
- sqlInsert(self, specificKeys=None, table='segyTrace', traceNumber=-1, fileKey=-1)
- Build an SQL string to INSERT the values for the current trace
SEE CREATE...
FIX: CorrelatedTraces and BinGainRecovered are bools, but I treat them as ints
FIX: maybe check self.drv if this function is provided by the driver.
traceNumber - a trace does not know its number. Set it if you
know it! the traceNumber is which trace position in
the header. Not necessarily shot number!!!
FIX FIX FIX: deal with things that are not integers!!!
