Global Mapper v25.0

Importing, combining and cropping xyz elevation data

Hello,
I am new to global mapper, but am looking for a way to import two xyz files (longitude, latitude, elevation), combine them to one xyz file and then crop it and export only a smaller selection of the combined file. How do I do this? Thankyou.

    1. Load both files into Global Mapper
    2. Export the data to an XYZ file.  On the Export Options dialog, you can choose the bounds for the export by entering coordinates or drawing a box.  
    3. If you need something more than a simple rectangle for your export bounds, then before you start the export, draw a polygon on the map and select it.  When you select the export bounds, you can choose to use the selected polygon as the bounds.
    Details on this topic can be found in the Exporting Data section of the Help file.
