    Hi, In direct graphic, to plot semi of points that is georeferenced I use the following: MAPSET to specify the projection in which the points coordinates are. PLOTS to plot each point(s) I like to know if this is possible to do the same thing using a graphic Object ('IDLgrPlot') ? if yes, how ? I'm struggly with this problem for days now, without any succes. Thanks in advance. Cheers. Antoine C.

    The object of choice for map line drawing is 'IDLgrPolyline' and the IDL helper functions that are designed to aid in the transform of lat/lon line data from your map's coordinate system and projection rules to the pixel cartesian coordinate system are MAP_PROJ_INIT and MAP_PROJ_FORWARD. The Online Help for MAP_PROJ_FORWARD provides an example, from which you should be able to extrapolate for your own data. James Jones ITT Technical Support
