    Default Importing UKOOA files

    Hi folks,

    Just to ask you if you ever considered the development of a way to import ukooa (seismic navigation files) into Globalmapper...

    I'm not familiar with that format. Do you have any more information on it and/or sample files in the format? For simply text file formats, it's often possible to directly import the data using the File->Open Generic ASCII Data File menu command.

    Let me know if I can be of further assistance.

    Thanks,

    Mike

    Hi Mike,

    First of all, thanks for your reply!!
    I`m including in this reply a brief description of the UKOOA file format:

    UKOOA P1/90 navigation data

    The UKOOA P1/90 format specification can be downloaded from SEG (or from local site). It's a fixed-position format without any <SPACE> or <TAB> separators between fields, so it can be hard to read. However, by inserting appropriate comment field in the header, it can be made much more legible, as this example shows:

    H0100 SURVEY AREA ISFJORDEN, SVALBARD
    H0101 SURVEY DETAILS SVALEX-2005
    H0102 VESSEL DETAILS R.V. HAAKON MOSBY
    H0104 STREAMER DETAILS 240 CH GECO NESSIE-3

    The lines starting with H2600 are just comments. You will notice that:
    Field in UKOOA P1/90 Position, start .. stop
    (leftmost = 1)
    NAME 2 .. 13
    SP = SHOTPOINT 20 .. 25
    LAT(ITUDE) 26 .. 35
    LONG(ITUDE) 36 .. 46
    UTM EAST(ING) 47 .. 55
    UTM NORTH(ING) 56 .. 64
    DEP(TH) (from echosounder) 65 .. 70
    D(AY) OF YEAR 71 .. 73
    TIME 74 .. 79

    Degrees (D), Minutes (M) and Seconds (S) of Latitude/longitude as given as (D)DDMMSS.SS. Notice the longitudes marked like this: 1414 3.08E. Here we have 3.08 seconds, and the leftmost field is simply vacant; the same applies to the Minute and Degree fields, should they only need one digit.

    This image explains better what I mean:

    The format looks pretty simple and very similar to the SEGP1 format that is already supported. I will get support added and point you at a new build when it is ready.

    Thanks,

    Can you send me a sample data file for this data? The cut and paste from your original email appears to have had some spaces removed making it not match the specified format. Also, so you know if there is a common extension used for these files?

    Thanks,

    I have sent you an example file this morning. Please let me know if you need more details.

    Best Regards,

    Juan,

    Thanks for the file. Based on that, I was able to get supported added under the SEGP1/UKOOA format. I have placed a new build at http://www.globalmapper.com/global_mapper9.zip with the change for you to try. Simply download that file and extract the contents into your existing v9.xx installation folder to give it a try. You will likely be prompted to select the format for the file when loading it. Just select 'SEGP1/UKOOA' and the file should load.

    Let me know if I can be of further assistance.

    Thanks,

    Mike

    Fantastic Job!!

    I works pretty well. Thanks a lot for your support....I think some geoscientists will enjoy this new improvement!!

    Just only a last question...Is it possible to display text for the LINENAME and SHOTPOINT loading the file once. In the image I`m attaching I did the job just loading the file twice...

    Many thanks again!!

    I have gone ahead and updated the importer to automatically use the shot point number for the point labels, so now just loading the file should by default get you what you are after. I have placed a new build at http://www.globalmapper.com/global_mapper9.zip with the change for you to try. Simply download that file and extract the contents into your existing v9.xx installation folder to give it a try.

    Let me know if I can be of further assistance.
