[Qgis-user] Looking for a suggestion on a vector format

[Nicolas Cadieux]

Hi, 
The standard file format in QGIS is the shape file (.shp) but it is and old format.  That will give you the better compatibility with other projects and all the QGIS plugins. 
I think going with spatialite vector file is probably the best option short of using an actual database.  Spatialite files are a single file (not 3 to 6 as in .shp).  But I expect some plugins will not be compatible.  In that case, you can always export stuff to a shape file. Both these file types can be reproject in any coordinate systems.  They are standardized and open. 
Stay away from dwg /dxf as they are mainly useful for engineers to lazy to learn GIS!  They are excellent for drawing in  AutoCAD but useless (IMHO) in the GIS world.

    All, 
      Before I go too far down the wrong path perhaps you can help me
    with a suggestion on a vector format to use for a project of mine: 
    
    
    I'm to looking to basically re-create various Instrument Approach
    Procedure plates (see here 
    for an example for San Francisco International - SFO ) from a
    database via a perl script and display a number of them as vector
    overlays in an existing QGIS project 
    
    What would be a good format to use for this purpose?  
    
    I'm imagining something like a QGIS project file, but I want it to
    contain to contain all of the various bits of information internally
    (coordinates, names, styling, icons etc.) and not have to query
    anything external so each file is a stand-alone unit.  
    
    Ideally all of the coordinates would be real world lon/lat so no
    transformation would be required.  Bonus points if the format is
    openly standardized and easy to work with 
    
    DWG/DXF?  SVG? 
    
    Thanks, 
      Jesse
