  • Poin name not displaying correctly when imported

    Hello,

    What version of Global Mapper are you using?

    Here is something that might help in Global Mapper 20.1:
    1. Double-click on your layer in the Control Center. This will bring up the Vector Options window.
    2. Click the Labels tab
    3. Under "Attribute Label Format Options", remove the check-mark next to "Automatically Format Numeric Attribute Values"
    4. Click OK
    Cheers,
    Bob

  • How to export KMZ with one layer only and transparency supported?

    Hello,

    To export one layer, right-click on the layer in the Control Center and choose Layers | EXPORT - Export Layer(s) to New File...

    To export one zoom level, on the KML/KMZ Options window, remove the check next to "Automatically Grid Export of Large Data Sets...(etc.)"

    To get transparency, specify the PNG format (as you already know) in combination with these other options.

    Cheers,
    Bob

  • Altering elevation values for an ASCII export

    Hello,

    The easiest way to get a good IMPORT command is to have Global Mapper do it for you as follows:
    1. Load your data into Global Mapper
    2. Use the Elevation Options | Alter Elevation Values tab to set the Maximum Valid Elevation and Minimum Valid Elevation
    3. Save a workspace
    4. Open the workspace file in a text editor such as Notepad.
    5. Copy the IMPORT command (you will likely also want the DEFINE_PROJ ... END_DEFINE_PROJ lines also so you will have the correct projection information) to your script file.
    Cheers,

  • How to find minimum/maximum value of an attribute

    gghiggini said:
    Wouldn't be possible to use 

    CALC_ATTR_FORMULA NEW_ATTR="newattr_2" FORMULA="Min(existingattr_1)"

    Hi Giorgio,

    The Max and Min functions used in the CALC_ATTR_FORMULA command do not operate on the entire data set. They return a result from the items in the list. For example, 
    CALC_ATTR_FORMULA NEW_ATTR="newattr_2" FORMULA="Min(existing_1, existing_2, existing_3)"
    will return the minimum value of the three attributes in the list. 

    If you are using the COPY_ATTRS command, MULTI_AREA=MIN or MULTI_AREA=MAX would copy the smallest or largest value of the attribute when multiple features intersect the area being copied.

    Cheers,
    Bob

  • 3D view not displaying coincident linework correctly (offset linework issues)

    Hello,

    I suggest that you contact Blue Marble Support directly via email (geohelp@bluemarblegeo.com) to address this. Please include a detailed description of your work flow, and data (CAD and DSM) that will reproduce the problem.

    Cheers,
    Bob
