RE: [geonet]: Large ascii data sets with no header or channel names

[David Humphrey]

Unless someone has a way to do this already using existing Oasis facilities, I would write a program (since I'm a programmer).  This is a natural application for a perl or python script.  For one experienced in one of these languages, this is a half-day type of project.  Rather than transforming the header into another header, one might just as well go ahead and import the data directly into a new Oasis database.  That being said, sorry, I don't have any code to offer.  This is a good one to add to the Oasis request list.

Subject: [geonet]: Large ascii data sets with no header or channel names

Does anyone have a GX or suggestion for converting a "typical" "Geoterrex" listing of column names (in a readme.txt) into a Geosoft "i3" import template.  For airborne data sets it can be a very tedious process to create an i3.  My current need is to import a data set with 140 data columns containing no header of column names. 

 

EXAMPLE OF README.TXT

 

PARAMETER     CHARACTERS         CONTENTS

 

   1            1-10       X                              (METRES)
   2           11-20       Y                              (METRES)       
   3           21-30       FIDUCIAL                       (SECONDS)
   4           31-40       FLIGHT NUMBER
   5           41-50       RADAR ALTIMETER                (FEET)
   6           51-60       BAROMETRIC ALTIMETER           (FEET)

(( deleted remaining channels))

 

EXAMPLE OF i3 FILE.

 

/ Wizard Generated Template for .\

[IMPORT ARCHIVE]
FILEHEADER   0
RECORDFORM   DELIM," \t","","","\""
SKIPSTRING "/"
LINENUMBER   4,6,NORMAL
   DATA 0,9,NORMAL,,,,

   DATA 1,10,NORMAL,,,,
   CHAN Y,DOUBLE,NORMAL,10,1,LABEL="Y"
   DATA 2,10,NORMAL,,,,
   CHAN FID,DOUBLE,NORMAL,10,1,LABEL="FIDUCIAL"
   DATA 3,10,NORMAL,,,,
   CHAN FLT,DOUBLE,NORMAL,10,1,LABEL="FLT_NUM"
   DATA 4,10,NORMAL,,,,
   CHAN RAD,DOUBLE,NORMAL,10,1,LABEL="RAD_ALT"
   DATA 5,10,NORMAL,,,,
   CHAN BARO,DOUBLE,NORMAL,10,1,LABEL="BARO_ALT"
