Global Mapper v25.0

Option to open Surpac .str and .dtm files

G'day.

Working in mining I frequently have clients send me .str and .dtm files that they have generated in Surpac which is very common (and expensive!) mining software here in Australia (see https://www.3ds.com/products-services/geovia/products/surpac/ for details).

Given its cost I don't own Surpac but would very much like to be able to open such files in GM (V22.1). Can anyone open these files currently in GM or could these file formats please be added as part of a future version? 

Cheers,
/al

P.S. I tried attaching sample .str and .dtm files to this post, but the interface wouldn't allow me to do for some reason??? I'm happy to email samples to anyone that private messages me...

    Hello,

    I have opened a feature request (GM-12242) so we can look into adding support for those Surpac file types. If you put the sample files in a ZIP archive, you should be able to upload them.

    Cheers,
    Bob

  • Thanks Bob, that would be awesome and would stop me frequently bugging Clients to resend their data as dxf or dwg!

    I have attached a zip file containing small example .str and .dtm files. These should import into any cartesian/grid system but are for a project in Western Australia with datum/projection = GDA94/MGA 51.

  • Just following up on this?

    Still a pain that we can't open Surpac (.str and .dtm) files in Global Mapper... ☹️

    Its inclusion would be greatly appreciated!

  • Any update on this GM HQ?

  • I also work in Mining and encounter Surpac .str and .dtm files all the time, so I would also find this very useful.

  • This would be much appreciated. I am always trying to convince my colleagues that they should purchase GlobalMapper as it is a workhorse and can convert almost any filetype. Sadly surpac files are not in yet!

  • Hi Guys,

    Any update on this?

    It's still painful in the mining world that we can't open Surpac .str and .dtm files in GM...

  • Hi Carrick,

    We have this issue too, but fortunately have an old copy of Surpac floating around the office. Without it though, there is a bit of free (Beta) software called GEM4D https://www.basrock.net/gem4d that you can get where you can save as .dxf which you can then bring into GM.

  • Thanks Nick- will give it a try!

  • Thanks again Nick - yes works like a charm!

    Now my question for BMG is, if this freeware can open Surpac .str and .dtm files how hard can it be to add them to the list of file types for GM?

    I was under the impression (obviously incorrectly) that the problem lay with 3ds.com (the owners of Surpac) and protecting their intellectual property, but it would appear that that is not the case.

    BMG can you please take a look at this feature request (GM-12242) again?

    Ta,

  • You're welcome mate, love a good workaround, but yeah would be fantastic if GM could open these natively.

  • Hi Blue Marble folks,

    Just giving this can another kick...?

    Any news on ability to open Surpac files (.str and .dtm format) in GM?

    Feature request (GM-12242)?
