  • Is there a tool that directly exports a .DWG map with coordinates to GEOTIFF?

    DWG files can look very different in Global Mapper compared the same file(s) opened in AutoCAD, especially if it has multiple layouts. If you are happy with your imported file then you can export it to GeoTIFF using Global Mapper.

    If you need to preserve the exact appearance of the original Layout; as seen after plotting, then I would plot the files to PDF with AutoCAD or Civil3D first. Then import the PDF into Global Mapper, choosing Import PDF as raster image. You would need to georeference the image before exporting it to GeoTIFF.
  • Exporting points e.g. Dot -Red as PDf to open in Illustrator.

    I found a simple workaround In Global Mapper.
    Prior to Exporting as PDF:
    1. In Global Mapper - Select all points in a layer.
    2. Use the "Create Range Ring./Ellipses" tool to convert the points to rings or squares and give them dimensions, fill, line colours.
    3. The converted points will present as a new G Mapper and can be renamed accordingly.
    4. Do this for all the point layers you want Illustrator to recognise as separate "like" objects. 
    5. Export as PDF.
    6. Illustrator will then recognise each exported (former) point layer as a diecrete group of "Objects" according to fill, line and can be manipulated accordingly.
    This dispenses with a real constraint.where Illustrator did not discriminate between diffent exported Point layers from G Mapper - even thourh they looked different, and regardless of their appearance as points, they had no fill/stroke attributes that coluld be changed in Illustrator.
    That is now a thing of the past. 
    Hope someone else can find it as usefrul (and calming) as I am.
  • Maybe not a software suggestion, but a billing one

    So disclaimer here, old semi retired curmudgeon here.  Still on V19 but about to go to 22/23.

    Long ago when the earth was still cooling (and Global Mapper reliably showed same), members here got a discount and purchasing was straightforward, and of course, less expensive (I know...see above under 'curmudgeon').

    I tried to renew online.  Price has gone up. OK.  Discount code no longer offered.  Well, OK.    Credit card convenience fee, of 4%.  Hmmm.. That's not really a thing in my province, so I looked up the practice in the US.  It's allowed, but it's the lower of 4% or what the credit card issuer charges.   Last I checked, my credit card charges everyone 2.4%.  Maybe I missed that along the way too.  So I called Visa.  Nope.  2.4% was the answer. 

    Now, 4% doesn't seem like a lot, until you throw in exchange rate and watch the price go north of $700 in my local currency.  Add in retirement budgets, you get the picture. 

    So I contacted Global Mapper.  Nice people, always.  This was no different.  Their approach was to offer alternatives.   I don't need to use a credit card, I can use a wire transfer or a cheque.  Well, cheque might work, let's see about wire.  I can send it for free, but I can't control handling fees after it leaves Canada.  Global Mapper will charge me whatever comes their way.  So I may get a hefty charge in US dollars, or not, no way of knowing.  Or, I can pay $35 US up front as a one time, coverall amount.  $35 USD =   6.3%!

    Now clearly one can argue that after paying $549 for software, $35 is nickels and dimes and that would be exactly right.  My question is, why extract these nickels and dimes from the users?  Most other vendors don't do this.  In fact, in the past year, it's been only this one transaction that I've seen it done.

    I know this is policy from somewhere up the food chain and really want to be fair to the front line staff who try to make it work every day and respond to emails within minutes.  Please don't take this as a poke at you.  I hope to renew.  But first, I think I need to get my BP back into 3 digits.   I'd make some comment about pulling my hair out, but thanks to my pandemic haircutting strategy, that would actually be an improvement....

    Rant off....

  • Local Mine Grid to GDA94-MGA51 Transformation

    Hi Al,

    Sorry for the late reply, I haven't been on the forum for a while. You've probably figured this out by now but if not, I've calculated the rotation and offset using the reference points using AutoCAD. 

    • Rotate 45 degrees clockwise (around the basepoint 0,0,0 if using AutoCAD)
    • x + 515232.1267
    • y + 6696002.975

    I have attached the xform (see zipped folder) so you can load it via Shift - Selected Layer(s) > Specify Coordinate Transformation > Load from File...

    I've tested it on the reference points and the DXF and they line up great.

    I often have to work these things out as the Mine Grid to the Projected Coordinate system has been lost or just isn't known. I also regularly have to work out what coordinate system has been used for data when the info isn't known to the Client.

    Anyway, this is my workflow for calculating the transformation:
    1. Plot 2 or 3 known points in both coordinate system (I draw a line between each of the points to trace a shape. This makes it easier to get your bearing when checking the rotation) 
    2. Make a copy of the Mine Grid shape and paste it onto the Projected shape and align to a common point
    3. Measure the angle difference between the two and make a note of it
    4. Delete the temporary shape
    5. Rotate the Mine Grid reference points around the basepoint 0,0,0 (origin) and enter the rotation angle noted earlier. AutoCAD is weird so 45 clockwise is 315 or -45.
    6. Now draw a rectangle between two common reference points
    7. Measure the width of the rectangle and note the difference in the x (easting)
    8. Measure the height of the rectangle and note the difference in the the y (northing)
    9. You will now have the rotation, and the x and y offsets.

    Good luck my friend

  • Is there a tool that directly exports a .DWG map with coordinates to GEOTIFF?


    After you load your DWG file into Global Mapper, you can export it as GeoTIFF. Is that what you are trying to do? If not, please provide more details.

  • how to create colour intensity image?


    is there anyway to create a coloured intensity image, not the black-white intensity image?

    Thank you
  • What operators do I use in a search string?


    This should work:
    %TEXT_DESCR% like '* hornfels'
    Note that based on your examples, I am assuming that there is always a blank in front of 'hornfels'. If that is not the case, just remove it from the search string.

  • Search Vector Data - Multiple Values

     %attr_1%  >= 1  and  %attr_1%  < 11

  • Out of Memory Error v22.1.1


    I suggest that you contact Blue Marble Support directly via email ( to address this issue. Please include a detailed description of your work flow, with screen captures of any options that are used, and the data set that is failing. Your data set is fairly large, so you probably won't be able to attach it to an email, but the support folks will provide instructions for uploading it. Thanks.

  • Layout orientation / rotation Map Layout Editor

    Is it possible to present a layout in the Map Layout Editor other than North up?

    If so, is there a possibility to Create a Feature Mapbook using the feature orientation?
    (In which case you can than draw and orient plotboxes in the 2d view, and automate importing those views in the Map Layout Editor using Create Feature Mapbook).
