Hi

In global mapper (11) are the distances measured using the Measure tool spheriodal or projected distances?

Thanks
David

    David,

    By default the distances are measured along the ellipsoid, but if you right-click in the Measure Tool there is an option to 'Use Grid Distance Rather Than Great Circle Distance' which allows you to switch this.

    Let me know if I can be of further assistance.

    Thanks,

    That is exaclty what I needed thanks

    On a similar theme when I export an XYZ from the 3d path profile then this is also ellipsoidal distances - is there a way of getting this as projected distances

    Thanks

    David,

    If you check the option in the Measure Tool to use grid distances, this should cause other measurements, like those in the path profile dialog (including exports from there) to use grid distances as well.

    Let me know if I can be of further assistance.

    Thanks,
