Thanks Michael, you cleared very well. I thought a shp has a scale because I
read on the shapefile-Wiki-page (http://en.wikipedia.org/wiki/Shapefile) the
following section:
The information contained in the .prj file specifies the:
Name of Geographic coordinate system or Map projection
Datum (geodesy)
Spheroid
Prime meridian
Units used
Parameters necessary to define the map projection, for example:
Latitude of origin
*Scale factor*
I have a big list of maps (worldmap, citymap...) in shp and want to sort
them by scale. Should I display all maps on JMapPane with same size and then
calculate the scale again.
Elly.
