Running Carlson v1.67 on an Allegro CX, converting an ASCII coordinate file to Carlson's CRD format seems to take an inordinate amount of time. It'd be easier (and certainly faster) for me to do this on my PC, but I'm not familiar with the CRD format. Can anyone point me to a format description? I'd rather not have to suss it out myself.

Thanks!

Carlson has a free desktop software, I think it's called xport or something like that. I don't convert on the Allegro very often but it doesn't seem to take that long. You could try upgrading your SurvCE, they have ver 2.58 now.

Jim, I haven't been surveying for roughly two years now but, and correct me if i'm wrong, could you designate an ASCII file for use as a control file and log your data to a new file created for your designed purpose?

Ebarnard67 is right, Carlson X-port will create a crd file from ASCII almost instantly on your pc. I think you should be able to download it free if you're already a Carlson user. .crd is quoted as a binary format file, opened in Notepad it looks like alphabet soup!

Unfortunately, a serial number is required for installation, and although one complimentary serial number is included on the back of the SurvCE manual, I don't have a manual (I bought the DC used).

It's definitely a binary format, though I haven't taken the time to figure it out yet. The encoding isn't obvious, but since the record sizes are pretty small it's probably not too complicated. You need to use a hex editor to many any sense of it; as you noted, a text editor won't correctly render the data.

FWIW, additional copies of Carlson X-Port are available for purchase... you can contact your local Carlson dealer and simply ask for pricing on Carlson part number 6501.699.000.

Otherwise, another option could be to download the "PC Demo" version of SurvCE via www.survce.com and use its File -- Import/Export routine (you'll need to supply your SurvCE serial number to access the proper Download page).

Thanks, Ladd -- that did the trick!
