The MGRSPoint class can not be resolved . I am using the import statement
import com.bbn.openmap.proj.*
which will include the package the MGRSPoint class is in, which is
com.bbn.openmap.proj.coords,
but then I make an instance of the MGRSPoint class the class can not be
resolved. I am trying to create an instance of the MGRSPoint class
passing a LatLonPoint as a parameter in the constructor, but as stated
previously the MGRSPoint class can not be resolved. Does anyone know
how to resolved this orhas ever used the MGRSPoint class and can shed
some light on how to get this to work?
Below is the class code and highlighed is where the MGRSPoint class can
not be recolved occurs.
Thanks
Steve
