Hello! I am trying to export a geotiff file from an online map source. The map is a raster format and with digitizer tool I am trying to export the features selected after a contour vector. Everything works, but after some time shows me Geotiff file error and the message "Error writing scanline". What should I do?

    What version of Global Mapper are you using? There were some builds a while back that had that error, but the latest should work fine.

    Thanks,

    Well I am using 13 version. And if I try to export the entire map says it-s too large for a normal tiff file and takes a lot.

    How large of an area are you trying to export and at what resolution? If you are getting the error about being too large for a normal TIFF you are trying to export a huge amount of data (more than 4GB or so of uncompressed data). I'm guessing perhaps you really want to use the Export Bounds tab to reduce your area of expoirt and perhaps also adjust the Sample Spacing to get a different resolution than the maximum.

    Thanks,
