[Xastir-dev] More Map Questions/Suggestions !

[James A Vincent]

Curt,

Thanks for all your help I have "expanded" a little on my questions.  Your ozi2geo script appears to work with the "ozi" maps I have.  If I find any probs I'll let you know - thanks for writing the script !

Yes, that is exactly what I want. It would be ideal if the LAT/LONG format matched that selected for the Xastir Co-ordiate system.

I'll try these sugestions. One problem is to select the zoom level. Would it be possible to select a zoom level directly rather than having to zoom in +/- 10% increments on a right mouse click.  It always seems to display zoom levels which are not what I want !

 Yes- Tom Russo has been very helpful.  I still haven't managed to discover the relationship between the colour=x and the colour displayed.  Is there a list of colours and their numerical value ?

Fair comment. Sometimes we British don't realise/accept that we are Europeans !
