HI,

I have a shapefile with polylines taken from SRTM data and I would like to convert this into a polygon shapefile.

I have GM 12.01, and am sure it is possible but i'm not sure how.

Thanks in advance

    You can select the lines with the Digitizer Tool, then press the toolbar button to convert lines into areas. You should really have closed lines for this to work well otherwise you will get odd areas in some cases. Once you have the areas you can export to an area Shapefile using the File->Export Vector Data menu command.

    Let me know if I can be of further assistance.

    Thanks,

    Thanks for the quick reply especially on a Friday night.

    Most of the lines are closed so thats no problem, when you say the 'toolbar button to convert lines into areas' where and what does this button look like?

    It's just Friday morning here :)

    The button looks like the attached and is also labeled with 'Create Area(s) from Line(s)'. You can also find it on the right-click menu in the Digitizer Tool.

    Let me know if I can be of further assistance.

    Thanks,
